Troubleshooting RTD Sensors
When troubleshooting a problem with an RTD input it is useful to check that the sensor and the
wiring to the instrument is operating properly.
The PIE CL514-PLUS automatically detects 2, 3 and 4 wire RTD connections with a patented circuit.
It will also display the connections on the display and indicate when there is a missing connection
due to a loose connector, corrosion or a broken wire.
Here is an example of the CL514-PLUS reading a
sensor with all 4 wire connected.
Here is an example where connections are made to a
4 wire sensor and the CL514-PLUS indicates that only
Wires 1, 2 & 4 are connected. There may be a loose
connection or a break in wire 3 somewhere between
the sensor and the CL514-PLUS.
Troubleshooting RTD Sensors
This is much simpler and quicker than going through
the process of testing each pair of wires to figure out
which, if any, connection is loose or which wire is
broken.
