mA Read Power Current Measurement
In this mode, the PCE-RTD 20 works as Loop Power Supply
while at the same time measuring
the current
.
Voltage Measurement
The PCE-RTD 20
is capable of voltage Measurement with two voltage measurement ranges.
The following picture displays the connection for Voltage Measurement for different mode.
RTD Terminals
Terminals for measuring and simulating RTD. For RTD/
Ω
types refer to the specifications.
RTD/Resistance simulation
The PCE-
RTD 20 is capable of RTD/Resistance generation.
The following picture displays the
connection for RTD and Resistance simulation. In RTD simulation RTD 20 mimics an RTD. The
instrument under test generates the current for the RTD measurement.
The PCE-RTD 20 controls the voltage across its terminals so that the resistance (voltage to
Current ratio) corresponds to the simulated temperature. Use of 2-, 3-or 4-wire connection is up
to the receiver instrument. Use only the two leftmost terminals with every wiring option. Connect
the possible third and fourth wire according to the
Requirements of the connected instrument but use only the two left most terminals.
