6.6 Set-point Resistance

The set-point resistance is the resistance the instrument is trying to make the

control sensor achieve and is calculatedin the firmware using the set-point tem-

perature. This value is not directly adjustable but is recalculated when the

set-point temperature is changed. The set-point resistance is used to perform a

calibration adjustment using the Callendar-VanDusen R versus T curve fit. The
