C) Ac Voltage Mode "V - VOLTCRAFT VC-337 Bedienungsanleitung

c) AC voltage mode "V

Follow the steps below to measure AC voltages:
• Turn the multimeter on and select "V
• Insert the red test lead into the V test socket (7), the black test lead into
the COM test socket (6).
• Connect both of the test leads to the measured object (e.g. generator or
mains voltage) in parallel.
The "V DC/AC" voltage range has an input resistance of
≥10 MOhm.
• After measuring, remove the test leads from the measured object and
turn the multimeter off.
Measurement of alternating voltages with a 400 Hz low-pass filter (VFC)
The current clamp is equipped with a 400 Hz software low-pass filter that suppresses noise above 400 Hz. The low-
pass filter can be switched on in the AC voltage range if necessary.
Never use the low-pass filter option to check the presence of dangerous voltages! The voltages present
may be higher than indicated on the device. Always carry out a voltage measurement without the filter first
to detect any dangerous voltages.
For AC voltage measurement with a low-pass filter, proceed as follows:
• Switch on the current clamp on the rotary switch and select the measuring function "V
• Press and hold the "SELECT" button (4) for about 2 seconds to activate the low-pass filter. 3 beeps sound and the
LCD display shows "UFC" for a moment. Then, the symbol "VFC" (P) appears in the display.
• Perform the measurement as described in the section "AC Voltage Measurement" (V
• To deactivate the low-pass filter, press and hold the "SELECT" button for about 2 seconds. A beep sounds and the
LCD display shows "End" for a moment.
