THERMOCOUPLE CONNECTIONS
Simulating or reading
thermocouples requires
the use of thermocouple
or extension grade
thermocouple wire.
Plug thermocouple wires into
the miniature thermocouple
jack or place bare
thermocouple wires
onto the brass block under
the screws.
The CL543B has two banana
jacks (1+ and 2-) mounted in
the top end of the housing.
These are not temperature
compensated and are to be
used only for millivolt signals.
RTD CONNECTIONS
Simulating or reading RTDs
uses copper wire. Plug 2-, 3- or
4-wires 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 uses patented
circuitry to automatically detects
if 2-, 3- or 4-wires are connected.
This is helpful to troubleshoot
sensor connections.
