Testing Resistance of the RTD Temperature Sensor
a. The resistance value (Ohms) of your temperature sensor depends on the temperature
of the sensor at the time it is being tested.

b. Measurements:
•
For DynaControl/ PLC: With an ohmmeter, contact pins 5 and 6 and measure
resistance.
•
For Controller MCV: With an ohmmeter, contact pins 8 and 12 and measure
resistance.
•
For Upgrade (NI RTD): With an ohmmeter, contact pins 3 and 5 and measure
resistance.
•
For Upgrade (Thermocouple): With an ohmmeter, contact pins 6 and 7 and
measure resistance.
•
For Upgrade (PT RTD): With an ohmmeter, contact pins 6 and 7 and measure
resistance.
c. A tolerance range of ± 10% is allowed. A sensor that tests outside of this range must
be replaced.
