4) 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.

AutoVA

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. Annunciators

“ ” 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.
