RTD/Resistance Source
PCE-MCA 50 is capable of RTD/Resistance generation.
The
following picture displays the connection for RTD and Resistance
simulation. In RTD simulation PCE-MCA 50 mimics an RTD. The
instrument under test generates the current for the RTD
measurement.PCE-MCA 50 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
leftmost terminals.
