Thermocouple Connection
Simulating or reading thermocouples requires the use of thermocouple or extension-grade thermocouple wire. Insert the thermocouple wire into the mini thermocouple jack or place the bare thermocouple wire under the brass block below the screw.
The CL543B thermocouple and RTD calibrator has two banana jacks (1+ and 2-) mounted on top of the housing. These are not temperature compensated and are for mV signal only.
RTD (PT100) Connection
Simulating or reading RTDs uses copper wire. Insert 2-wire, 3-wire, or 4-wire into the corresponding jacks on the calibrator. For RTD source, the CL543B simulates the (+) RTD from jacks 1 and 4 and the (−) RTD from jacks 2 and 3. When reading an RTD sensor, the CL543B thermocouple and RTD calibrator automatically detects whether it is a 2, 3, or 4-wire connection using proprietary circuitry. This aids in troubleshooting sensor connections.
