gradually until the readings have significant changes after
stabilization.
Do not submerge PRT handle when taking measurement.

3.5 Thermal EMF

Each AccuMac PRT has gone through an annealing process and
stability test to minimize the thermal EMF, which is caused by either
impurities of sensing element or temperature differentials at lead wires
connection point.

3.6 Over Heating

tm
The sensing element of AM1640 PRT is sealed inside an Inconel
sheath to ensure the best stability and repeatability. The seal can be
breached if the PRT is over heated for an extended period of time.
