BEAMEX MC5P - Using a Compensation Loop; 2-Wire System

Advanced Operation and Configuration
Using a Compensation Loop
MC5P sources current through the resistor
and the compensation loop from the two
left side terminals. MC5P measures the
voltage drop across the entire current loop
and across the compensation loop. If the
compensation loop and the connection
wires of the resistor are identical, MC5P can
compensate for the resistance of the con-
nection wires.
When the compensation loop wiring sys-
tem is used, MC5P displays the text “3-
wire”.
2-wire System
Calibrator sources current through the
resistor and measures the voltage drop
across the same terminals.
The result is acceptable, if the resistance
of the connection wires is low.
