N2O Monitor 3010 1.0 INTRODUCTION 1.1 General The Bacharach N2O Monitor 3010 is easy to use, but it is essential that this instruction manual be read and understood by all operators and maintenance personnel prior to using or servicing the monitor. The 3010 is a compact and lightweight N2O monitor that displays the current level of N2O gas in either the range of 0 to 1,000 ppm, or a Time Weighted Average (TWA) ppm value, or an elapsed time (twa) ppm value.
N2O Monitor 3010 1.3 Units of Measurement The monitor’s LCD shows N2O concentrations expressed as either a current (real time) ppm reading, or a time weighted average ppm value displayed in either upper case (TWA) or lower case (twa). The TWA/twa ppm value is calculated either over a set 8-hour period (TWA), or over the total elapsed-time period that the monitor was switched ON (twa).
N2O Monitor 3010 2.0 OPERATION 2.1 Important Note Always ensure that the monitor’s gas inlet connector (Figure 1, Item B) and outlet (Figure 1, Item D) are unobstructed and open to the atmosphere. Be careful not to breath directly on the monitor while taking a measurement; otherwise, inaccurate N2O readings will result. 2.2 Switching the Monitor ON/OFF Switch ON the monitor by momentarily pressing the button.
N2O Monitor 3010 2.3 Start-Up Display The display that appears when the monitor is first turned ON depends on what Time Weighted Average mode the monitor is currently in, and how long the monitor has been OFF. Refer to Section 2.6 Time Weighted Average (TWA/twa) Mode. or If the monitor is in its 8-hour ‘TWA’ mode and was OFF for more than 8 hours, then the first display appears at turn-on, which identifies the monitor and shows the countdown of the monitor’s 30 minute warm-up period.
N2O Monitor 3010 2.5 Normal ppm Mode This mode provides real-time readings of the N2O concentration present in the surrounding area. The monitor’s display is toggled between its TWA/twa and normal ppm modes by pressing the f1 button. In this mode the gas level shown on the display is the current gas level that is being detected by the monitor. For example, the following display shows that the current detected N2O level is 120 ppm.
N2O Monitor 3010 If the monitor is switched OFF and then back ON before 8 hours has elapsed, then the operator has the option of continuing the current TWA reading by pressing the f2 button as described in Section 2.3 Start-Up Display. This is intended for instances such as lunch breaks where the unit is switched OFF for a short time, but the total TWA is required.
N2O Monitor 3010 2.7 Time Weighted Average Alarm The 3010 monitor has a built-in Time Weighted Average alarm whose trippoint is based upon the selected format—either 8 hours (TWA) or continuous (twa). The factory default alarm level is zero (no alarm), but can be activated by using the optional BACH-COM software. When the alarm is tripped, the monitor emits a beeping tone that remains on until the TWA/twa level falls below its trip point.
N2O Monitor 3010 While in the auto-stablization mode, and with a non-changing level of N2O being detected, the monitor automatically cycles the pump ON and OFF for one minute intervals. Measurements taken during this time allow the monitor to automatically correct the readings for any drift. When a change in the N2O gas level is detected, the monitor interrupts the cycle of turning the pump ON and OFF and keeps the pump ON. Once the gas level stabilizes, the process of cycling the pump ON and OFF resumes.
N2O Monitor 3010 2.10 Pump Operation Important! The restrictor (Figure 1, Item C) must be removed for the pump to operate in the ppm mode; otherwise, the monitor will automatically enter the auto-stablization mode as described in Section 2.8. With the monitor already switched ON, momentarily pressing the f3 button turns the internal pump ON. Pressing f3 again turns the pump OFF. We recommend attaching the supplied particulate filter (Figure 1, Item M) to the gas inlet connector whenever the pump is used.
N2O Monitor 3010 2.12 Battery Low Display When the battery voltage falls below a pre-determined level, the display will alternate between its gas display and the following BattLow display: The monitor’s beeper will also emit three rapid notes every 30 seconds. At this time the monitor should be given a full charge per Section 3.1 Battery Charging as soon as possible. 2.13 Battery Charge Indicator An indication of the battery’s charge state is shown as a bar graph on the right side of the display.
N2O Monitor 3010 2.15 Powering Monitor from Charger The monitor can be continuously powered by the charger as follows: Important! To ensure accurate readings, the instrument must be connected to the charger for at least 1 hour before using it for testing purposes. 1. Turn ON the monitor without the charger attached. Note: Connecting the charger to a monitor that is OFF causes the monitor to enter its charging mode, which in turn prevents the monitor from being switched ON. 2.
N2O Monitor 3010 3.0 MAINTENANCE 3.1 Battery Charging When the “BattLow” message is displayed (refer to Section 2.12), the monitor must be recharged using the supplied battery charger. Important! The battery has a long shelf life, but it is recommended that the battery be recharged once a month if left unused. Batteries that have not been charged for several months should be given at least two charge/discharge cycles before using the monitor.
N2O Monitor 3010 3.2 Cleaning Keep the monitor clean by wiping it with a soft cloth dampened with a mild detergent solution. The monitor can be sterilized by using isopropyl wipes. Do not immerse the unit in any sterilization agent. 3.3 Sunlight The unit should not be left out in direct sunlight, or in other areas where excessive heat exists, for long periods since component damage due to overheating may result. 3.4 Servicing There are no user-serviceable parts inside the monitor.
N2O Monitor 3010 WARNING! After resetting the monitor to its factory settings, a zero calibration must now be performed per Section 3.7 before the monitor is used for testing purposes. 3.7 Zero Calibration There are two methods available to perform a zero calibration: • Clean Air (preferred method) • Zero Gas (alternative method) Note: Span gas calibration is not required. The monitor is digitally calibrated and has a linear curve relationship between 0 and 1,000 ppm N2O.
N2O Monitor 3010 3.7.1 Clean Air Calibration Important! An air-cal should be done in clean ambient air, NEVER in the actual test area. Keep in mind that poorly ventilated areas may contain high background levels of CO2 (over 1000 ppm) that could result in a 5 to 10 ppm offset in the N2O reading. An unoccupied room or corridor is best suited to do an air-cal. NEVER do an air-cal near an open window as the temperature change may affect the accuracy. 1.
N2O Monitor 3010 WARNING! This procedure assumes the use of a Bacharach Calibration Kit as listed in Section 4.1. If a non-Bacharach gas regulator is used, then an in-line flow meter must also be used to ensure that the gas flow into the monitor is approximately 100 cc/minute. Improper flow can cause erroneous gas readings. 1. If not already done, switch ON the monitor per Section 2.2. 2.
