5.7
EnerSave function
If you press the [ON/TEST] key to start a measurement, it will be terminated automatically after
10 seconds. If you wish to measure for a longer time, press and hold the [ON/TEST] key until you
hear a short sound, which means that the EnerSave function is disabled.
The EnerSave function must be disabled everytime you wish to make a longer measurement.
5.8
[LOW
Ω] key for continuity tests
Press the [LOW Ω] key to make a continuity test. A short circuit current of 200 mA will be used.
The meter can display very small resistances of up to 0.01 ohms.
5.9
[
LOW Ω] key for Auto Zero
Press the [LOW
Ω] key to zero the resistance, the test leads and the fuse. This function is useful
if you use longer test leads.
Do not forget to short-circuit the test leads when making a zero setting.
5.10
[1000V] key for power off (Auto Power Off)
Press and hold the [1000V] key for 5 seconds to switch off the meter.
After 5 minutes without pressing any key, the meter will turn off automatically.
5.11
Automatic discharge after an insulation measurement
After each insulation measurement, the meter will be discharged automatically. The status of the
discharge will be displayed in the meantime. The discharge is finished when no voltage is present
any longer. Before that, the test leads must not be removed.

Safety checks before the measurement
Check the cables for damage and cracks and replace them, if required. Also inspect the fuse
before each measurement by holding the test leads against each other in [LOW
Ω] mode. At the
same time, the measurement resistance will be set to zero. Always connect the test leads to the
circuit to be measured safely and correctly. Never interrupt the connection during a measurement
and do not touch the test tips or the sample as the safety mechanisms are not fully effective during
the measurement. Always follow the instructions on the display. Do not start a measurement
before the test leads have been properly connected to the sample.

Changing the fuse
In order to change the fuse, follow these steps:
First remove all test leads. Now open the battery compartment and remove all batteries. Now
open the case by loosening both screws in the battery compartment. Now you can change the
fuse. Close the meter and re-insert the batteries. The meter can be used again when the battery
compartment has been closed.
