Testing the Sensors
A good quality test meter capable of measuring up to 5,000 kΩ (1 kΩ = 1000 Ω) is required to measure the sensor resistance. In addi-
tion to this, the actual temperature must be measured with a good quality digital thermometer.
First measure the temperature using the thermometer and then measure the resistance of the sensor at the iSeries-S. The wires from
the sensor must not be connected to the iSeries-S while this test is performed. The wiring terminals are easily removed by pulling them
from the iSeries-S. Using the chart below, estimate the temperature measured by the sensor. The sensor and thermometer readings
should be close. If the test meter reads a very high resistance, there may be a broken wire, a poor wiring connection or a defective
sensor. If the resistance is very low, the wiring may be shorted, there may be moisture in the sensor or the sensor may be defective.
To test for a defective sensor, measure the resistance directly at the sensor location.
