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 “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.
