WARNING
– To avoid possible electric shock or personal injury,
ensure that you are aware of the voltage level
without the LPF enabled. There may be a possible
presence of hazardous voltage, and voltages
measured with the LPF enabled may be greater
than indicated. For your safety, take note of the
symbol. Disable the LPF when you have
finished your measurement.
– When the LPF option is selected, the measurement
function will switch to the manual range mode
(defaults to 600 V) for variable speed drive (VSD)
applications. It is recommended only to use 600 V
and 1000 V in the manual range for VSD testing.
