3.
To troubleshoot the transmitter independently of the sensor, use an appropriate
resistor across the temperature input connectors and connect the conductivity
inputs to resistance decade box.
8.2.5
Systematic troubleshooting
If the quick troubleshooting guide does not resolve the error, try the step-by-step
approach offered in in the flowchart below.
1.
Follow the troubleshooting flowchart.
2.
Refer to the tests and instructions indicated by the flowchart to diagnose the
problem.
8.2.6
RTD resistance values
Table 8-5
is a ready reference of RTD resistance values at various temperatures. These are
used for testing and evaluation of the sensor.
NOTICE
Resistance values are read across the RTD element and are based on the manufacturer's stated
values (± 1%). Allow enough time for the RTD element in the sensor to stabilize to the
surrounding temperature.
