4. Measuring and testing
4.1 General information
The voltage tester switches on automatically when
a voltage of at least 12 V is applied or switches
automatically to voltage testing.
Note:
For voltages below 12 V, the device must be swit-
ched on by the button
or switched to voltage by
the button
Ω
/ V
.
The instrument switches off automatically
approximately 30 seconds after the last
measurement.
Note:
It is possible that the voltage tester switches-on
automatically when only one test electrode is
connected to voltage or to a statically charged
object. This has no significance.
4.2 Testing voltage
Attention!
The self-test (see section 3.3) has been carried out
successfully.
Securely contact the test electrodes with the testing
points.
