Measuring positive and negative currents (bipolar operation): In applications
measurement range. The ammeter’s rear calibration potentiometer compensates for
full-scale input variations up to ±1% (49.5 to 50.5mV).
where both positive and negative currents must be measured, Murata Power Solu-
tions recommends using ‘-DC4’ 8-36V isolated supply models. Negative current
fl ow is denoted by the illumination of the display’s negative (–) sign; the absence of
a negative sign implies positive current fl ow. Contact MPS if you have any questions
regarding bipolar operation of DCA5-20PC ammeters.

➁ On non-isolated ‘-DC1’ models, continuous application of single-ended ±400mV
➂ Breakdown (isolation) voltage applies only to ‘-DC4’ isolated-power models.
➃ Zero reading is measured with TB1-1 (–IN) shorted to TB1-2 (+IN).
➄ Power supply currents noted are measured with the 50mV shunt input (TB1) at
➅ Each model’s full-scale display reading with a 50.0mV input is designated by the

inputs will not damage the ammeter. Single-ended inputs are defi ned as those
whose TB1-1 (–IN) potential is within ±0.1V of the potential on TB2-2 (-V). For
all models, the application of short-duration (5 seconds max.) ±1V inputs will not
damage the ammeter.
Breakdown voltage is tested with TB1-1 tied to TB1-2 (–IN shorted to +IN) and
TB2-1 tied to TB2-2 (+V shorted to -V). 500Vdc is then applied between the
two shorted terminal-block pairs; the max. allowable leakage current is 5uA.

fi rst X in the DCA5-20PC-X-XXX model number structure. Decimal point selection
(DP1, DP2, DP3, or none) is performed by the user to suit desired amperage range.
Input ranges -1, -2, -3, -4, -7, -8 and -9 can accommodate 100mV shunts. For these
ranges, the indicated 50mV reading is doubled when a 100mV input is applied.
Accessories:
With respective decimal point user enabled. See technical note 7.
