Wiring Diagram
Direct, alternating and pulsating voltages of up to 253 V can be
measured between the V and COM socket terminals.
• Measurements with the voltage measuring input of the volt-
meter function (V–COM), electrically isolated from the mains
Setting Measuring Parameters
Test Sequence, DUT at Test Socket (e.g. for measuring safety
extra-low voltage at power packs or chargers)
➭ Set the rotary switch to the U position.
➭ Set the parameter to V – COM (with mains).
➭ Connect the DUT’s mains plug to the test instrument’s test
socket.
Attention!
!
Use only the included, contact-protected KS17-ONE
measurement cables when measuring dangerous volt-
age.
➭ Connect the DUT’s output sockets to the V and COM sockets,
e.g. in order to be able to measure a safety extra-low voltage at
the DUT’s output.
➭ Start the test: press the START/STOP key.
➭ V-COM (with mains) Acknowledge the warning which in-
dicates that line voltage will be connected to the test
socket.
➭ Switch the device under test on.
➭ The measured values are displayed. The measured
value recording symbol shown at the right appears.
Each time this key is pressed, the currently displayed
measured value is saved to buffer memory.
➭ Turn off the device under test.
➭ End the test: press the START/STOP key.
The save symbol appears (floppy disk showing the
number of measured values stored to buffer memory)
and prompts you to save the measured values to an 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.
