Adjacent current-carrying devices such as transformers, motors and conductor wires will
affect measurement accuracy. Keep the jaws away from them as much as possible to
minimize influence.
Hi-Z DCV, ACV & Line-Level Hz functions
Set the slide-switch function selector to the
position selects common impedance (Hi-Z)
voltage measurements. Input impedance is set at approximately 5M
Ω
to minimize loading on
circuits under tests. DCV is the default function. The DC annunciator “
” turns on.
Press
SELECT
button momentarily to select ACV. The AC annunciator “
” turns on.
Press momentarily again to activate the Line-Level Hz function.
Note:
•
Line-Level Hz input sensitivity varies automatically with ACV range selected when Line-
Level Hz is selected. AC 6V range has the highest and AC 600V range has the lowest
sensitivity. Measuring the signal in ACV function WHILE selecting Line-Level Hz function in
that ACV range automatically sets the most appropriate sensitivity for higher voltage
applications. This can avoid electrical noises as in 110/220V line voltage applications for
