Initial operation
Inserting the batteries
Before the initial operation of this meter, you must first install a new 9V block (alkaline) battery. A power pack
unit can be used optionally. Battery installation and power pack operation are described in the „Maintenance
and cleaning“ section.
Connecting the measuring sensor
Connect the round plug of the sensor (17) with the socket „PROBE INPUT“ (6) on the measuring device. The
plug is protected against wrong polarity and only fits into the socket in the right direction. Observe the arrow
marking on the plug. This marking points towards the back of the device. Make sure that the plug is firmly
inserted otherwise inaccurate measurements will be made.
Setting up the measuring device
For better reading, the measuring device can be set up using the bracket on the rear (13).
The device can be mounted on a tripod using the tripod socket (10)
Automatic cutoff function
To save on the unnecessary usage of battery power, an automatic switch-off function has been built-in. The
device is automatically switched off if no button has been pressed over a period of about 3 minutes. You can
switch the device back on with the „Power“ button (3).
