Chapter 2 __________________________________________________________ Product Overview 0901-017 Figure 2 Typical Connections and Cables Pressure Measurement The PTB330TS uses a PTB330 series digital barometer that is housed in a tabletop casing. The barometer does not come with its own display and keypad; instead, it is designed to be operated using the handheld MI70 indicator. The MI70 indicator also provides the operation power for the barometer.
User's Guide ______________________________________________________________________ 0810-032 Figure 3 PTB330 Barometer in Tabletop Casing Numbers refer to Figure 3 on page 20: 1 = MI70 holder 2 = M12 connector for MI70 connection 3 = Pressure port Pressure Measurement Principle PTB330 uses a BAROCAP® silicon capacitive absolute pressure sensor developed by Vaisala for barometric pressure measurement applications.
Chapter 2 __________________________________________________________ Product Overview Humidity and Temperature Measurement (Option) An optional HMP155 humidity and temperature probe is available for the PTB330TS. HMP155 provides reliable humidity and temperature measurement in a wide range of applications. Humidity measurement is based on the capacitive thin film polymer sensor HUMICAP®180R. Temperature measurement is based on resistive platinum sensors (Pt100).
User's Guide ______________________________________________________________________ 0910-033 Figure 4 HMP155 Probe with Additional T-probe Chemical Purge (Option) Chemicals in the measured gas may interfere with the humidity sensor of the HMP155. The sensor polymer absorbs the interfering chemical, gradually reducing its ability to absorb water molecules. Consequently the sensor gain decreases.
Chapter 3 ________________________________________________________________ Operation CHAPTER 3 OPERATION This chapter contains information that is needed to operate the PTB330TS. Transport Before transporting the PTB330TS, make sure that all instruments are securely placed in the foam interior. The inside of the case should be clean and dry. If water has entered the case due to operation in the field, let it dry before closing. The transport case has an air pressure release valve below the handle.
User's Guide ______________________________________________________________________ A shoulder strap is included with the transport case. The attachment holes for the shoulder strap are located on the handle; see Figure 6 on page 24. The other two holes on the case can be used to lock the case with a padlock (not supplied).
Chapter 3 ________________________________________________________________ Operation NOTE The MI70 indicator is also used in other Vaisala products, such as the Vaisala HUMICAP Hand-Held Humidity and Temperature Meter HM70. Because of this, the MI70 indicator has some software features and accessories that are not relevant for the PTB330TS, and are not described in this manual.

You can switch the MI70 indicator off during recording to save battery. Display message tells you that recording continues undisturbed even when power is off.
User's Guide ______________________________________________________________________ Saving Individual Data Points You can save the currently displayed readings in memory using the Hold/Save function. When in the basic display, press the Hold/Sa shortcut button to freeze the currently shown readings., and press Save to save the data point in memory. The data points are are saved as individual files, and identified by the saving date and time. The files remain in memory even if the indicator is turned off.
Chapter 3 ________________________________________________________________ Operation - Number of recorded data points - Recording interval Alarm Function The MI70 indicator can produce an alarm when a measured quantity is outside the allowed range. The range is controlled by setting the lower and upper limits. When the alarm is active, the indicator will show an alarm message, play a beeping sound, and blink the display backlight. The alarm can only be set for one quantity at a time.
User's Guide ______________________________________________________________________ MI70 Link Interface Software for Data Handling Recorded data can be transferred from the MI70 indicator to a PC by using MI70 Link Interface Software. You can examine the recorded data easily in Windows environment and transfer it further to a spreadsheet program (such as Microsoft Excel) or virtually to any Windows program in numeric or graphical format.
Chapter 4 ______________________________________________________________ Maintenance CHAPTER 4 MAINTENANCE This chapter contains information that is needed in maintenance of the PTB330TS. Cleaning You can clean the transport case and the barometer enclosure with a soft, lint-free cloth moistened with mild detergent.

User's Guide ______________________________________________________________________ Changing the Sensor in the HMP155 If your HMP155 uses the HUMICAP® 180R sensor, you can change it yourself without sending in the probe for service. After changing the sensor, you must calibrate the new sensor using serial line. For instructions on how to change the sensor and calibrate it, refer to the HMP155 User’s Guide. It is available for download from www.vaisala.com.
Chapter 4 ______________________________________________________________ Maintenance Calibration and Adjustment of PTB330 In PTB330, the raw measured pressure value of each barometer module is first corrected using the corresponding multipoint adjustment values. The additional linear adjustment (if enabled) is applied to the corrected values.
User's Guide ______________________________________________________________________ attempting to readjust the barometer module. As the previous linear corrections will disappear when new linear corrections are input, the user has to take into account the previous linear corrections when deciding about the new ones. NOTE Entering new linear or multipoint corrections will always cancel the previous corrections.

User's Guide ______________________________________________________________________ Key in the linear corrections for each barometer module separately. Feeding ON or OFF as a parameter enables or disables the linear correction. A single question mark shows the reading and reference information stored and the state of the linear correction. Each barometer module has its own adjustment commands. If there are three barometer modules installed, the commands LCP1, LCP2, and LCP3 will be available.
Chapter 4 ______________________________________________________________ Maintenance The command operates like LCP1, but can take up to eight reading/ reference pairs. If there are three pressure barometer modules installed, the commands MCP1, MCP2, and MCP3 will be available. First deactivate the previous corrections by using the MPCP1 OFF command. Precalibration of the transmitter then gives the required corrections.
User's Guide ______________________________________________________________________ Entering Adjustment Information Adjustment information and date are a part of the device information that is shown using the ? command. Use the CTEXT and CDATE commands to enter updated adjustment information. CTEXT Use the CTEXT command to enter text to the adjustment information field. Example: >ctext Vaisala/MSL Calibration text : Vaisala/MSL > CDATE Use the CDATE command to enter date to adjustment information field.
Chapter 4 ______________________________________________________________ Maintenance Calibrating and Adjusting Relative Humidity 1. Check that the MI70 indicator is connected to the HMP155, and turn it on. Set the correct time, date, and environmental settings (pressure compensation) if prompted. 2. Start the chemical purge from the Functions menu, if available. After the chemical purge is complete, allow sufficient time for the probe to reach ambient temperature before continuing. 3.
User's Guide ______________________________________________________________________ 4. Activate the adjustment mode by holding down the ADJ button on the probe until the message below appears on the MI70 display. 0811-086 Figure 23 5. Starting Adjustment Mode for HMP155 Press OK to move on to the adjustment and select RH as the quantity you want to adjust. 0811-087 Figure 24 Select Quantity 6. Check the environment settings if prompted. 7. Insert the probe into a known reference environment.
Chapter 4 ______________________________________________________________ Maintenance Calibrating and Adjusting Temperature NOTE If your HMP155 has the additional temperature probe, you cannot calibrate the temperature sensor on the HMP155 probe using the MI70 indicator. However, you can do so using the CT command on the serial line. Additional calibration and adjustment methods are provided in the HMP155 User’s Guide, which is available for download from www.vaisala.com. 1.
