The specified Full-Scale Current is the current carried by the single wire passing through the
center hole of the ACA5-20PC's on-board CT. It is not the load current ultimately being
measured. the Overcurrent Rating is a continuous rating that applies to the Full-Scale
Current. It does not apply to any circuitry external to the meter.
Listed accuracy specifications apply over the range of the Rated Full-Scale Current over
frequencies of 45-450Hz.
Maximum reverse polarity protection on "DC1" models is –40Vdc, and –50Vdc on "DC2"
models. "DC3" models provide no reverse polarity protection.
All specified maximum power supply currents are steady-state. AC-powered models can
draw larger surges at initial turn on.

Technical Notes
IMPORTANT! To ensure safe and reliable operation, ACA5-20PC
ammeters must be installed and serviced by qualified technical
personnel. Contact DATEL if there is any doubt regarding
ammeter installation and/or operation.
1. Measurement Type: ACA5-20PC ac ammeters employ a full-wave-
rectified, average responding, rms-calibrated circuit to measure the
stepped-down output of their built-in L1 current transformer (CT) .
Stated accuracy specifications are measured using a sine-wave
current at or close to the full-scale input level, at nominal line
frequency.
2. Calibration: Periodic recalibration of ACA5-20PC ammeters is not
required under normal, indoor operating environments. If user
calibration is necessary, it should be performed by qualified technical
personnel. Calibration is performed with potentially lethal voltages
applied to the ACA5-20PC and its associated wiring, with the specified
full-scale current flowing through the ammeter’s built-in current
transformer. A plastic, fully-insulated adjusting tool must be used to
access the recessed calibration potentiometer located on the back of
the meter (see Mechanical Specifications). Contact DATEL if additional
information is required regarding calibration, setup, or any other
technical issue pertaining to ACA5-20PC ammeters.
3. Wire Gauges and Fusing: Wires specified in the Functional
Specifications section must be used for making connections to ACA5-
20PC Series ammeters. All power-supply and load wiring must be
rated for the supply voltages and currents they will conduct and must
comply with any code or application-mandated requirements pertaining
to the user’s specific installation.
