thermistor resistance at 25°C, manufacturer, and the measurement accuracy
required.
The factory default configuration for the temperature measurement circuit is for it
to be disabled. This is done by setting the three thermistor calibration constants
C1, C2 and C3 to zero. Doing this disables the temperature display on the front
panel and also prevents the output from being disabled due to an open or shorted
thermistor circuit.
In order to use the temperature measurement feature of the LDX-36000, nonzero
values for the Steinhart-Hart constants must be entered. Using an uncalibrated
ILX Lightwave 10 k @ 25°C thermistor, the typical values shown in Table 3.3
may be entered to give a measurement accuracy of approximately ±2°C. If higher
accuracy is required, a calibrated thermistor must be used.

To display temperature being meaured, the T button within the Display 2 Adjust
box must be pressed. See Figure 3.6.
