which means rectangular-shaped voltage waveforms, and waveforms
with sharp transitions, will read lower than their true-rms value. For

ACM20 VOLTS readings when powered from four ac waveforms.
The 140Hz bandwidth limit does not apply to the WATTS reading nor
to the AMPS reading. The circuitry used for these two measurements
has an upper bandwidth of 14kHz. ACM20 power meters are mains
operated devices designed to measure ac currents and voltages,
within the speci?ed limits previously noted. DC currents and voltages
will not be measured accurately.

After the unit powers up to normal operation in the VOLTS reading
mode, momentarily (approximately one second) touching the ‘SEL’
button on the unit’s front panel three times in succession will cycle
the display to AMPS, WATTS, and end at PF (or HERTZ for ‘–F’ mod-
? Speci?ed full-scale currents are those passing through the power meter’s built-in current
transformer’s primary load-circuit.
? The overcurrent rating of 1.5 x the rated full-scale current is a continuous rating and applies
to the current passing through the built in current transformer. Accuracy is guaranteed up to
the rated current.

els). Momentarily touching ‘SEL’ a fourth time will return the display
back to the VOLTS reading mode.
Holding the ‘SEL’ button down for 3 seconds will place the unit in a
continuous auto-cycling mode, and the display will repetitively scroll
through all four measurements, with each measurement remaining
displayed for 3 seconds.
