Measuring Other Parameters
Simultaneously
Connect Vaisala interchangeable dewpoint (DMP) or humidity (HMP)
probe to the MI70 indicator's other connector port to have simultaneous
humidity measurement.
1. Connect the DMP70/HMP70 probe to the other connector port in
the bottom of the indicator.
2. Turn on the MI70 device.
3. Check that the pressure settings of the probes (port I and II) are the
same if you are taking measurements from the same condition. You
can use the HMP70 probe's temperature data to compensate the
CO
2
measurement. In this case, select YES when the MI70 asks you
to check the environmental settings. Then select temperature T and
press SET. Now the MI70 asks if you want to link the measured T
value to environment parameter, press LINK and EXIT.
4. The display now shows the reading of the port I probe in the upper
row(s) and the reading of the port II probe in the lower row(s).
5. For achieving the most accurate measurements, set the actual
temperature value measured with the temperature and humidity
probe to the GM70.
