When you start to use DM70 for the first time, see MI70 first start-up settings. Otherwise follow the instructions below.
- Connect the probe to the MI70 indicator.
- Press the Power On/Off button.
- Install the probe to the measuring position. If you are measuring in pressurized processes, see Connecting to pressurized processes using DSC74 sampling cell. When using other sampling cells than DSC74, make sure that the threads are compatible with the probe threads (G ½" ISO228/1). Be careful not to damage the sintered filter when installing the probe.
- Before measuring, make sure that the air pressure settings of DM70 are correct and that autocalibration has taken place (see Automatic autocalibration).

The basic display opens. Let the reading stabilize.
CAUTION If you need to disconnect the probe from the indicator, first press the Power On/Off button to turn the indicator off. This ensures that all the settings and data are saved properly
When measuring low dew points, the stabilization times can be long, for example, 1 ... 2 hours. Therefore, turn off the automatic power-off function, turn on the automatic autocalibration, and turn on the automatic sensor purge.
This allows monitoring the stabilization, the autocalibration ensures an accurate measurement, and the purge ensures the shortest possible response times.
