Turn on the steam generator. As steam begins to flow, watch the dial gauge and the ohmmeter.
When the thermistor resistance stabilizes, record the resistance (Rhot) in Table 1. Also record
the expansion of the tube length (DL) as indicated by the displacement of the indicator on the
dial gauge. (Each increment on the dial gauge is equivalent to 0.01 mm of tube expansion.)
Note that DL is the difference betwen the dial gauge readings.
