4.1 Lead Wire Identification
The 5623A PRT is equipped with a four-wire cable (see Figure 1). Four lead
wires are used to cancel lead wire resistance. For best results, the readout de
-
vice should be equipped to handle four-terminal resistors.
The lead wires are two different colors. Lead wire pairs attached to each end of
the sensor are identified by red and white insulation.
