Operating Manual
3.2 Operating and maintenance
1. Battery Operation
The battery has been used up and needs to be replaced, if ´bAt´ is shown in lower display. The device
will, however, continue operating correctly for a certain time.
The battery has been completely used up, if ´bAt´ is shown in the upper display.
2. The battery has to be removed, when storing device above 50°C.
We recommend to remove the battery if device is not used for a longer period of time!
Risk of leakage!
3. Treat device and probes carefully. Use only in accordance with above specification. (do not throw, hit
against etc.). Protect plugs and sockets from soiling.
4. Mains Operation
When using a power supply unit please note that operating voltage has to be 10.5 to 12 V
DC. Do not apply over voltage!! Simple 12V-power supplies often have excessive no-load
voltage. We, therefore, recommend using regulated voltage power supplies. Trouble-free
operation is guaranteed by our power supply GNG10/3000.
Prior to connecting the plug power supply with the mains supply make sure that the operating voltage
stated at the power supply is identical to the mains voltage.
5. Cable break or no connected / too dry / highly insulating material:
There may still corresponding %-values are displayed
- This shall not constitute a valid test result!
6. Maintenance: The device does not contain serviceable parts inside.
Regular inspection of contacts and cable is suggested, the precision of the measuring chain can be
checked with the optional testing adapter GPAD 38
The measuring needles have to be fixed very well e.g. by means of a wrench. Loose needles can disturb
the measuring.
3.3 Start up and readiness for operation
After switching on the instrument, a self test is performed (approximately 5 seconds).
During this time all display segments are shown.
After this sequence the instrument changes to measuring operation and is ready for use.
