Current Measurement
The PCE-LOC 20 supports current measurement using either PCE-LOC 20 as the loop power
supply while at the same time measuring the current or simply measuring the current while an
external power supply is used.
The following picture displays the connection for Current Measurement for different mode. And
also different ways of providing the supply power to the loop.
mA Current Measurement
In this mode, the PCE-LOC 20 is not providing any supply voltage. For proper measurement, the
external device should be capable of providing the voltage supply. If the external device is not
capable, an external Power Supply should be connected in series.
mA Read Power Current Measurement
In this mode, the PCE-LOC 20 works as a Loop Power Supply
while at the same time measuring
the current .
Voltage Measurement
The
PCE-LOC 20 is capable of voltage Measurement with two voltage measurement ranges.
The following picture displays the connection for Voltage Measurement for different mode.
