Chapter 1 _________________________________________________________ General Information CHAPTER 1 GENERAL INFORMATION Safety Throughout the manual, important safety considerations are highlighted as follows: WARNING Warning alerts you to a serious hazard. If you do not read and follow instructions very carefully at this point, there is a risk of injury or even death. CAUTION Caution warns you of a potential hazard.

Chapter 2 _________________________________________________________ Product Description CHAPTER 2 PRODUCT DESCRIPTION The PTB210 series digital barometers are designed for various pressure ranges. The barometers with an analog output are available with different scalings between 500 ... 1100 hPa for 0 ... 5V or 0 ... 2.5V. The PTB210 series barometers are also available with a digital output. The PTB210 series barometers offer an excellent solution for outdoor installations.
User's Guide _______________________________________________________________________ The PTB210 barometers incorporate the BAROCAP® silicon capacitive absolute pressure sensor developed by Vaisala. The sensor features excellent hysteresis and repeatability characteristics and has an outstanding temperature and long-term stability.
Chapter 3 ________________________________________________________________ Installation CHAPTER 3 INSTALLATION Mounting Due to the compact design of the PTB210, all you need to do is to mount the instrument, and to connect the wires. Use one of the following three mounting options. - Remove the pressure fitting, and place the barometer on a desired structure. Then, fix it with the slot headed screws, the O-ring sealing the attachment (A).
User's Guide _______________________________________________________________________ NOTE Check that the cable is not taken upwards from the barometer. This is to prevent water flowing along the cable, and gathering close to the feed-through. Figure 4 Recommended Cable Position The IP65-classified housing enables the barometer to be mounted outdoors without any additional protection. However, please take care that rainwater cannot plug the open pressure fitting.
Chapter 3 ________________________________________________________________ Installation Connections Connect the wires of the PTB210 barometer according to Table 1. Use the pink wire for the supply voltage (8 ... 18 VDC), and the blue wire for grounding. The output signal is read from the white wire and grounded with the brown wire. The gray and green wires are used to connect the barometer to PC when using the calibration Wizard software, or to Vaisala PMI20 digital barometer display.

Chapter 4 ___________________________________________________ Calibration and Adjustment CHAPTER 4 CALIBRATION AND ADJUSTMENT The PTB210 series barometers can be fine adjusted and calibrated against pressure standards that have high accuracy and stability as well as known traceability to international standards. By comparing the output to a reference, the user can define the corrections required for readjustment. NOTE Calibration is considered not to involve any adjustments.
User's Guide _______________________________________________________________________ Operation •To start the Wizard program in NT: 1. Double-click the My Computer icon. 2. Double-click the drive that contains the file. 3. To start the program, double-click the WIZARD.EXE-file. OR •To start a program by using the Run command in NT 1. Click Start, and then click Run. 2. In the Open box, type the location and name of the program you want to start.
Chapter 4 ___________________________________________________ Calibration and Adjustment 3. Give reference pressure values and the corresponding corrections. Calculate the corrections according to the equations below. NOTE Because the lower end of voltage output is not exactly 0 V, use as lower calibration point a value approximately 40 mV above the lower end limit. Thus with scale 600…1060 hPa and 0…5V output the lowest calibration point will be 604 hPa.
User's Guide _______________________________________________________________________ Reference Correction 4. To save the new corrections, click the Write PTB210-button.
Chapter 4 ___________________________________________________ Calibration and Adjustment 5. The program then asks a password. As default, no password exists. Just click OK. The password can be used to prevent saving of any new corrections without entering it. To give a password, click the Change-button. 6. Enter a new password and confirm by re-entering it. NOTE Remember to set the MPC corrections on after given them.
