Temperature Test
Before you do the temperature test:
1. Make sure that you have the necessary equipment. See Table 2.
2. Make sure the Product battery is good and replace it if necessary. See “Battery
Replacement”.
3. Warm up the Calibrator as necessary. Refer to its specifications.
4. Let the temperature of the unit under test (UUT) become stable to room temperature
(60 minutes minimum).
To do the temperature test:
1. Connect the Product to Calibrator with the K-type thermocouple wire and the
thermocouple connector. See Figure 2.
2. Apply the input level for each step shown in Table 3.
3. Compare the indication on the Product display with the UUT reading limits in
Table 3.
4. If the display indication falls outside of the range shown in Table 3, calibration
adjustment or repair of the Product is necessary. See “Calibration Adjustment”.
