Operation
CAUTION: Before and after hazardous voltage measurements, test the voltage function on
a known source such as line voltage to determine proper meter functioning.
VFD-ACV
Hz
& ACV
Hz
functions
Inputs are made through the test leads terminals.
VFD-ACV
Hz
function is to deal with VFD (Variable Frequency Device) signals. It, however,
further pre-selects the most appropriate voltage-ranges and thus the Hz trigger levels to best
cope with most VFD-Voltage and VFD-Frequency applications.
Note: The Hz trigger level is determined by the AC/DC+AC Voltage or Current function-range
being in use. Press RANGE button to select different function-ranges and thus trigger levels
manually.
DCV & DC+ACV
Hz
functions
Inputs are made through the test leads terminals. Defaults at DCV Function. Press SELECT
button momentarily and release to select DC+ACV
Hz
.
ACA
Hz
, DCA & DC+ACA
Hz
functions
Input is made through the clamp jaws for non-invasive current measurements. Defaults at
ACA
Hz
Function. Press SELECT button momentarily and release to select the subject functions
in sequence.
