Table 1.3 Warnings and cautionary statements °C (32 °F), the stabilization time is approximately 15 minutes; with smaller or larger changes in temperature, stabilization time will be shorter or longer, respectively. Note: If the sensor is to be zeroed after a sudden change in ambient-air temperature, allow the sensor and its readings to stabilize before zeroing. The Long-life O2 sensor (part number 17155304-Y) is a biased sensor, requiring continuous power to operate to specification.
Table 1.3 Warnings and cautionary statements Battery contacts are exposed on batteries when they are removed from the instrument. Do not touch the battery contacts and do not stack batteries on top of each other. Do not use solvents or cleaning solutions on the instrument or its components.
Table 1.3 Warnings and cautionary statements The batteries are not user-replaceable. The aspirated version of the Ventis Pro 4 and Pro 5 is approved for use with the P/N 17148313-2 extended battery only. To be charged on the surface or underground in accordance with 30 CFR 75.340 (the applicable regulations pertaining to battery-charging stations) and MSHA Program Information Bulletin PIB P11-12. Charge monitors with an Industrial Scientific Corporation charger designed for use with this monitor.
Bump Test (or "functional test") Bump testing is a functional test in which an instrument's installed sensors are to be briefly exposed to (or “bumped” by) calibration gases in concentrations that are greater than the sensors’ low-alarm setpoints. This will cause the instrument to go into low alarm and will indicate which sensors pass or fail this basic test for response to gas. Zero Zeroing adjusts the sensors’ “baseline” readings, which become the points of comparison for subsequent gas readings.
Note: The use of calibration gases not provided by Industrial Scientific may void product warranties and limit potential liability claims. First use To prepare the Ventis Pro Series instrument for first use, qualified personnel should ensure the following are completed: • Charge the battery. • Review instrument settings and adjust them as needed. • Calibrate the instrument. • Complete a bump test. Wearing the instrument Based on the U.S.

2 Product Information Instrument Overview System Overview Key Features Compatibility Specifications Instrument Overview The Ventis® Pro Series portable gas monitors are used for personal protection to monitor for oxygen and a variety of toxic gases and combustible gases. Thirteen compatible sensors are available for use with the Ventis Pro4 Multi-Gas Monitor, which can provide readings for up to four gases.
• • Provide its user with a panic alarm. Self-activate a man-down alarm when it senses it is no longer being operated by its user. When part of a LENS Wireless group, the Ventis Pro can operate as a “peer” equipment item. Peer instruments share with one another their gas readings and alarms, allowing workers to learn of nearby hazardous conditions and the user names of colleagues who may be in distress.
RGX Gateway iNet Instrument data RGX Gateway iNet Now users (live monitoring and subscription-based alerts) Ventis Pro Wi-fi Battery Instrument data Figure 2.1 Industrial Scientific live-monitoring system Key Features LENS Wireless Ventis Pro instruments are equipped with LENS Wireless, a long-range, power-efficient wireless mesh network from Industrial Scientific, which enables the wireless connection of gas-detection instruments and other equipment items to form a LENS group.
With a setting of on, the wi-fi battery is operational—it is not turned on or off by the worker. However, the instrument can be set to allow its user to update the battery’s network credentials, during startup or during operation, using an iAssign tag that is programmed with the proper credentials. When a wi-fi battery is installed, but its setting is turned off, the following apply. • The battery will power the instrument.
The man-down feature allows the instrument to sense when it has not moved. A man-down warning or alarm may indicate the instrument operator is unable to move or press the panic button, or that the instrument has become separated from its operator. Both the warning and alarm can be turned off by the user. An instrument’s man-down functionality can be temporarily disabled when the instrument’s site name is updated by an iAssign Beacon that is broadcasting a special site name.
Gas-information access Optional gas-information displays are used to provide the instrument operator with the setpoints for gas events and calibration gas concentrations. The information can be set to display during the start-up sequence, be accessible during operation, or both. DualSenseTechnology DualSense® Technology enables the use of redundant sensors, two installed sensors of the same type that are DualSense capable.
Compatibility Sensors Each instrument’s compatible sensors can be installed in one or more specific locations as depicted in Figures 2.2.A and 2.2.B for Ventis Pro4 and Ventis Pro5, respectively. Table 2.1 provides the same information but in list format, which is helpful for distinguishing among sensors of the same type. For example, there are two H2S sensors that do not share installation locations or part numbers.

To join a Ventis Pro Series instrument to a Radius BZ1 instrument, choose the "Join new peer" option on the Radius; this is accessible from the Wireless menu's Wireless Peer options. Joining in progress Leave group confirmation Then, point the Ventis Pro IrDA window at Radius IrDA window.
Leaving a LENS group There are three ways for an instrument to intentionally leave a group without activating group-related warnings. • The operator accesses the instrument's LENS Wireless peer list and chooses the "Leave Group" option. As shown below, if the instrument is in a named group such as Group A, the group name is indicated onscreen. • The instrument's LENS group membership is changed, either by manually joining another group or through settings. • The instrument is docked or powered off.
Live Monitoring iNet Now, a service of Industrial Scientific, is part of a wireless system that enables the live monitoring of gas-detection instruments. Instrument data travels wirelessly to iNet. From iNet, the safety team, using iNet Now, can learn on a live basis of in-field conditions including gas events and operator events like mandown and panic alarms. Live monitoring requires* the following. • Activation of the iNet Now service. • Activation of the instrument (through iNet) for live monitoring.
Man-down Functionality An instrument’s man-down functionality can be temporarily disabled. This can occur when the instrument’s site name is updated by an iAssign Beacon that is broadcasting a special site name. For example, a company cafeteria may have a Beacon set to this signal to temporarily prevent instruments at rest from causing man-down warnings or alarms. The Ventis Pro display screen will feature a symbol ( ) to indicate the man-down feature is not operational.
When an instrument is in alarm, its display will feature a symbol that indicates the event type. LENS peer alarms use the same or similar symbols; samples are shown below.
Warnings (sample display screens) Instrument warnings Man-down warning Gas-present alert Instrument issue Maintenance required 120-second pre-alarm countdown. H2S gas-present alert. LEL sensor failure. Bump test due for CO and H2S.
6 Alarms, Warnings, and Notifications Overview Alarms Warnings Indicators Failures and Errors Overview This chapter provides in-depth information about alarms, warnings, and notifications; portions of this text appear in abbreviated form elsewhere within this product manual. Alarms notify the instrument operator of danger. Warnings notify of a condition that needs attention. Indicators notify of a status (e.g., confidence indicator).
display; if two or more peer alarms are active, they will all be acknowledged with a single press of the enter button . When the instrument has more than one active alarm (or active peer alarm), the display will cycle through messages for each event; however, when the instrument is in alarm, it will not display peer alarms. Instrument alarm events are distinguished from one another through the use of symbols (see Table 6.1) that appear on the display screen.
Table 6.1 Alarm events (list) Alarm symbol Alarm level Alarm event Peer low Peer gas present (low-alarm) Peer low TWA Description For some instrument alarms, the display screen provides alarm details in multiple formats, which alternate during the event. For example, a high-alarm gas event has three possible display formats as described and shown below for an instrument that is in high alarm caused by the CO sensor reading, which is now at 100 ppm.
Alarm level: High Gas present, over-range alarm — Gas present, high alarm STEL alarm — Critical low battery alarm System alarm Man-down alarm Panic alarm Alarm level: Low Gas present, low alarm TWA alarm — 92
Alarm level: LENS peer high Peer gas present, high alarm Peer STEL Peer panic alarm Peer man down Alarm level: LENS peer low Peer gas present, low alarm Peer TWA — — Figure 6.1 Alarm events (display screens) Warnings Warnings turn on and off repeatedly. The more urgent the warning, the shorter the time between on-off occurrences: a warning that repeats every two seconds is more urgent than a warning that repeats every thirty seconds.
Table 6.2 Warnings (list) Symbol Warning Description Man-down The instrument has not moved for the set period of time. To turn off the warning, move the instrument. Gas alert A detected gas concentration may be approaching alarm levels. To turn off the warning, press and hold . LEL-Low O2 LEL and O2 sensors are installed and the concentration of O2 is insufficient for LEL sensor functionality. Sensor failure One or more sensors is not working.

Indicators Most indicators turn on once, then off; only the confidence indicator persists, repeating every 90 seconds. If all signal* settings are on, indicators will look and sound like this: Indicator Status Color iAssign update, calibration, or bump test Success Blue iAssign update, calibration, or bump test Failure Red Confidence indicator Instrument on Blue Sound Beep *Signals (visual, audible, and vibration) vary based on instrument settings.
Table 6.3 Failures and errors If desired, repeat the calibration process. ! and gas reading A sensor that was operating in DualSense has failed. The remaining sensor is operating as a single sensor. Respond according to company safety policy. When a failure is caused by conditions other than those listed above, an error code will display. Some indicate a possible installation error or compatibility issue; qualified personnel may attempt to resolve these and other errors (see Table 6.4 below).
7 Maintenance Guidelines Process At-a-glance Supplies and Preparation Instruction Guidelines This chapter provides instruction for manually completing these utilities: bump testing, zeroing, and calibration. These procedures can also be completed using compatible Industrial Scientific docking stations and accessories that are supported by iNet, DSSAC, or Accessory Software. Elsewhere in this product manual (Chapter 1), are the definitions and recommended practices for each procedure.
• • • View the results. Remove the calibration cup. Turn off the gas cylinder. Supplies and Preparation Use Figure 7.1 as a guide to gathering supplies and preparing the calibration gas cylinders.
Instruction Figure 7.2.A through 7.2.C provide maintenance instruction in this order: zeroing, calibration, and bump testing. The standard process is shown for calibration and the quick process is shown for bump testing. When a process varies from those shown below, the instrument will supply instruction on its display screen.
Calibration progress Calibration results When the calibration is completed, the instrument will display a calibration results of passed or failed, along with the sensor's span reserve percentage. — Passed Cancel calibration The span reserve percentage is an indicator of the sensor's remaining life. When that value is less than 50%, the sensor will no longer pass calibration.
Bump testing (quick process shown) Place the prepared calibration cup over the instrument case top. Visually inspect the calibration cup to ensure its edges along the top and sides align with the instrument case top edges. Press down to secure the cup in place; a click will sound.
Table 7.1 Calibration failure: possible causes and recommendations Possible causes for calibration failure Recommendations The sensor's span reserve percentage is less than 50%. The sensor is due for replacement. The gas cylinder did not contain the calibration gas in the concentration needed. Repeat the calibration with a suitable gas cylinder. When all sensors fail, this may indicate the calibration gas did not reach the sensors. Check for the following.

Optionally charge the instrument after reassembly. Using a torx screwdriver, loosen all four captive screws on the battery. Lift the battery away from the instrument. Using a torx screwdriver, loosen the case bottom's remaining two screws. Hold the case bottom near the upper screws.
Sensor setup and replacement Sensor setup Sensor replacement (LEL sensor shown) — If a battery is attached to a sensor, separate the battery from the sensor where the two circuit boards meet. Dispose of the battery according to company policy. Hold the sides of the sensor firmly then pull it straight up and away from the instrument. Some sensors, such as the LEL sensor shown here, include a small circuit board that should detach from the instrument board when the sensor is removed.
Charging Rear insert position Forward insert position Place the battery against the case bottom. Using a torx screwdriver, tighten the screws. See Table 8.1 for torque value. If the charger includes an insert, adjust the insert to ensure the battery contacts touch the charging contacts. Once the insert is placed into the desired position, a firm push down will secure it in place. To prevent loss of the insert, keep it in the cradle in its mostused position.
Warranty Industrial Scientific Corporation’s Ventis® Pro Series portable gas monitors are warranted to be free from defects in material and workmanship under normal and proper use and service for as long as the instrument is supported by Industrial Scientific (excludes sensors, batteries, filters, and pumps). O2, LEL, CO (excluding COSH or CO/H2 Low), and H2S sensors are warranted for three years from date of shipment.
Appendix A Supplemental Information about Gases and Sensors Toxic Gases A sensor is designed to detect for and measure the presence of a particular gas, the "target gas"; however, it may also respond to other gases. When this is the case, the sensor is said to have "cross-sensitivity" to another gas, which will interfere with the target-gas readings. Table A.
Combustible Gases Tables A.2 and A.3 provide the LEL for select combustible gases as they apply to specific sensors. These tables also provide correlation factors that can help determine the percentage LEL when the actual gas differs from the gas that was used to calibrate the instrument. For example, if the instrument reads 10% LEL in a pentane atmosphere, and was calibrated to methane, the actual percentage LEL is determined as follows: 1.
