Autova Tm Function - Amprobe ACD-45PQ Manual De Uso

AutoVA TM Function
Set the slide-switch function-selector to the
• With no input, the meter displays "
• 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.

• 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 600A is input via the jaws, the meter displays the
ACA current value. Annunciators "
• 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.
CAUTION
�
• For non-invasive ACA current measurements, press the jaw trigger
and clamp the jaws around only one single conductor of a circuit
for load current measurement. Make sure the jaws are completely
closed, or else it will introduce measurement errors. Enclosing more
than one conductor of a circuit will result in differential current (like
identifying leakage current) measurement. Locate the conductor(s) at
the Jaws center as much as possible to get the best measuring accuracy.
For removal, press the jaw trigger and remove the jaws from the
conductor(s).
• 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.
