The Digi-Meter is used to monitor welding voltage
and amperage of constant voltage and constant
current arc welding power sources, and engine-
driven welding generators. This unit is not designed
to measure primary voltage and amperage.
Typical applications for the Digi-Meter include test
labs, field operations and repair shops. The digital
meters are very accurate (±1%) and can be used to
check and monitor the welding output for setup,
calibrating, test procedures, etc. Can be used in
straight or reverse polarity.
The voltmeter displays the output voltage to the
nearest tenth of a volt (0 to 100 volts). The ammeter
displays the output amperage to the nearest
ampere. The meters may be connected in either the
positive (+) or negative () weld output cable.
When in the standard position, the meters will
continuously display the existing amperage and
voltage values of the welding operation. When the
arc is broken, the meters will display zero amperes
and zero volts (or open circuit voltage, depending
on the power source). In standard, the meters
always display the output of the power source.
The hold position maintains the meter display as
follows: Once an arc is established, it will take
approximately 10 seconds of welding time for the
meters to stabilize, at which point they will hold the
amperage and voltage values present at that time
for the duration of the weld and for approximately
15 seconds after welding stops. When the 15 seconds
have elapsed, the meters will clear to actual power
source output (zero amperes and volts or zero
amperes and open-circuit voltage, depending on
the power source.) Restriking the arc before this
15 seconds has elapsed resets the meters and the
selected meter operation resumes.

RMS is the value of AC voltage or current that will
generate the same amount of heat in a circuit
containing only resistance that would be caused
by a DC voltage or current of the same value. The
effective value is called RMS (root-mean-square).
Note that the AC sine wave illustrated has a peak of
31.2 volts. This has the same effect as a straight line
of 22 volts DC. An RMS meter connected to this
circuit would show a reading of 22 volts. A DC
meter will read zero.
