Direct, alternating and pulsating voltages of up to 253 V can be
measured. Two connection types are available, one of which has
to be selected in the parameters menu.

Test Procedure
➭ Set the rotary switch to the U position.
➭ Connect the DUT’s mains plug to the test instrument’s test
socket.
➭ Start the test: Press the START/STOP key.
➭ PE-P1 (with mains): Acknowledge the warning which in-
dicates that line voltage will be connected to the test
socket.
➭ Switch the device under test on.
➭ Contact the ungrounded output for safety extra-low voltage
with test probe P1.
➭ Polarity can be set via direct selection immediately be-
fore measurement is started, without having to switch to
the parameters menu.
➭ The measured values are displayed. The measured
value recording icon shown at the right appears. Each
time this key is pressed, the currently displayed mea-
sured value is saved to buffer memory.
➭ Turn off the device under test.
➭ End the test: Press the START/STOP key.
The save icon appears (floppy disk showing the num-
ber of measured values stored to buffer memory) and
prompts you to save the measured values to a test ob-
ject ID number.
➭ Press the ESC key in order to discard the measured
values stored to buffer memory and acknowledge by
pressing the key shown at the right.
