Before and after hazardous voltage measurements, test the voltage function on a
known source such as line voltage to determine proper meter functioning.

function
Set the slide-switch function-selector to the
position.
With no input,
the meter displays “
” when it is ready.
With no ACA current input via the jaws but a voltage signal above the nominal threshold
of DC 2.4V or AC 30V (40Hz ~ 500Hz) up to the rated 600V is present on V-COM
terminals, the meter displays the voltage value in appropriate DC or AC, whichever
larger in peak magnitude. Annunciators “Auto” “dc” and “Auto” “
” turn on respectively.
On the contrary, with no voltage signal present on V-COM terminals but a ACA current
signal above the nominal threshold of AC 1A (40Hz ~ 500Hz) up to the rated 1000A is
input via the jaws, the meter displays the ACA current value. Annu
nciators “
” and
“Auto” turn on accordingly.
The Auto-VA feature stays at the auto-selected function as long as its signal remains
above the specified threshold. Press
SELECT
button momentarily to manually select
and lock (annunciator “Auto” turns off) thru the functions ACA, ACV, DCV and then goes
back to Auto-VA.
