Displays the most critical measurements in mains-powered
equipment: voltage, amperage, active power (watts or Kilowatts),
and power factor. A front panel selector-switch provides two
modes of operation: a fi xed reading of any of the four param-
eters, or a continuous cycling through all four measurements.
All ACM20 multi-function power meters include built-in current
transformers—no other user-supplied components are required.
Built-in shunts for DC currents to 20A

•
•
The fi rst digital DC ammeters to include built-in low loss shunts
for measuring currents up to 20A. Six ranges provide for preci-
sion measurement of DC currents from 200μA to 20A. These
ammeters are 100% self-contained, so no calibration or user-
supplied components are required.
External shunts for DC currents to 2000A

Scales and displays the output of 50mV and 100mV DC-shunts.
Twenty-fi ve ranges provide for measurement of DC currents from
1A to 2000A. With the exception of an external shunt, the unit is
100% self-contained—no calibration or additional components
are required.
Displays AC Volts, Amps, Watts, and Power Factor
Two display modes: continuous auto-cycling or fi xed reading
Universal 85-264Vac (47-63Hz) operating range
