4) OPERATION

AutoVA

function

Set the slide-switch function-selector to the

position.

●With no input, the meter displays "Auto" 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. LCD annunciator "dc" or "

" turns 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. LCD annunciator "

" turns

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

thru the functions ACA, ACV, DCV and then goes back to Auto-VA.

CAUTION

●For non-invasive ACA current measurements, press the jaw trigger and clamp the jaws
