Vaisala MI70 measurement indicator is an accessory that you can use as a display or as a communication device for HMP155. When you use MI70, HMP155 is powered through it.
You can calibrate HMP155 easily on site with MI70. You can calibrate both the active output version and the passive output version.
- In the active output version, you can calibrate and adjust relative humidity, temperature, and additional T-probe temperature.
- In the passive output version, you can only calibrate and adjust relative humidity.
-
Activate the adjustment mode by holding down the ADJ button on
the probe until the message below appears on the MI70 display.
-
Select OK to move on to the adjustment and select the quantity
you want to adjust.
The list of quantities varies depending on the configuration of your HMP155.
