8.8.14 Temperature Sensor Checkout
An accurate ohmmeter must be used to check resistance values shown in Table 8–3 or Table 8–4 .
Due to variations and inaccuracies in ohmmeters, thermometers or other test equipment, a reading within 2% of
the chart value would indicate a good sensor. If a sensor is bad, the resistance reading will usually be much higher
or lower than the resistance values given in the tables.
Two preferred methods of determining the actual test temperature at the sensor, is an ice bath at 32°F (0°C) or a
calibrated temperature tester.
