VOLTCRAFT VC880 Notice D'emploi page 50

j) 1 kHz Low-Pass Filter Alternating Voltage Measurement
Never use the low-pass filter option to test for presence of dangerous voltages! The present volt-
ages may be higher than indicated.
Always perform voltage measurement without the filter first to recolonise any possible dangerous
voltages.
The DMM is equipped with an alternating current low-pass filter. This is an alternating voltage measurement routed
through a low-pass filter that blocks undesired voltages exceeding 1 kHz.
Proceed as follows for AC voltage measurement with the low-pass
filter:
- Switch on the DMM and select measuring range "
- Plug the red measuring line into the V measuring socket (7) and the
black measuring line into the COM measuring socket (8).
- Now connect the two measuring prods to the object to be measured
(generator, circuit, etc.). The measured value is indicated on the
display.
- After measuring, remove the measuring lines from the measured
object and turn off the DMM.
