• Select 100, then press ENTER.
• From the THERMISTOR SETTINGS menu, choose SENSE-MODE, then press
ENTER.
• From the SENSE MODE menu, choose 4-WIRE, then press ENTER.
• Press EXIT as required to return to normal display.
5. Repeatedly press the DISPLAY TOGGLE key until the sensor resistance (RT) is dis-
played on the lower display line on the right. For example: RT: +099.98
Ω
.
6. Verify that the sensor reading for the 100
Ω
resistance in Table 1-3 is within stated
limits.
