➀ Specifi ed full-scale currents are those passing through the ammeter’s built-in
➁ The overcurrent rating of 1.5 x the rated full-scale current is a continuous rating
➂ Specifi ed accuracy applies to inputs with crest factors (CF) up to 2.0, where CF
➃ All specifi ed maximum power supply currents are steady state; larger surge

it does not apply to any external circuit-wiring or external loads. Accuracy is
guaranteed up to the rated current level.

Ordering Information
IMPORTANT! To ensure safe and reliable operation, ACA-20RM
ammeters must be installed and serviced by qualifi ed technical
personnel after reading this data sheet in it's entirety. Contact DATEL

operation.

current transformers (CT). Stated accuracy is measured using a sine-
wave input at, or close to, the specifi ed full scale input, at a nominal
line frequency of 60HZ.
required under normal indoor environments. If user calibration is
deemed necessary, it must be performed by qualifi ed technical
personnel since potentially lethal voltages and currents are applied to
the ACA-20RM during the calibration process.
Calibration is performed with approximately 95% of the specifi ed
full-scale current fl owing through the ammeter’s built-in CT. A fully
insulated, non-metallic adjusting tool must be used to adjust the
calibration potentiometer, located on the back of the ammeter (see
Mechanical Specifi cations section).
