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 525Plus 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 525Plus reading a 
sensor with all 4 wires connected.

Here is an example where connections are 
made to a 4 wire sensor and the PIE 525Plus 
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 
525Plus.
