6. Operating with MI70 Indicator
6.1 Overview of MI70 Support
The MI70 hand-held indicator is a convenient service tool for viewing the measurement
readings and performing calibration and adjustment. MI70 is used as the display and
configuration tool in, for example, the HM70 Hand-Held Humidity and Temperature Meter, and
is also compatible with various Vaisala probes and transmitters.
You can use the MI70 indicator for the following tasks with HMD60:
• Measurement viewing and logging
• Calibration and 1-point adjustment (see Calibration and Adjustment with MI70 Hand-Held
Indicator (page 40))
• Viewing information about the transmitter (serial number, SW version, last adjustment
date)
To connect HMD60 to an MI70 indicator, you need the optional MI70 connection
cable (Vaisala order code 219980SP).
