Current Measurement
The PCE-TTC 30 supports current measurement using either PCE-TTC 30 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-TTC 30 does not provide any supply voltage. For proper measurement the
external device should capable of providing the voltage supply. If the external device should not
capable, an external Power Supply should be connected in series.
