Item Function
1 SOFT CUTOUT and HARD CUTOUT are limit parameters that shut off power to the heat
source if the well temperature exceeds the set limit value.
The Soft Cutout is a safety barrier to protect probes from temperatures more than their
specified temperature limits.
The Hard Cutout protects the Calibrator from irreparable internal damage. See “Set Soft
Cutout” on page 31.
Note:
The Soft Cutout is user configurable and should be set within 5°C to 10°C above
the temperature limit of the instrument being calibrated. The Hard Cutout is not
user configurable and is set by the factory to approximately 160°C.
If the cutout is activated because of an excessive well temperature, the Calibrator enters a
“Cutout mode” where power to the heat source is shut off to immediately cool the
Calibrator and instrument. When in Cutout mode, the instrument displays
“CUTOUT”
above the Stability Status indicator. The instrument stays in Cutout mode until the
temperature is below the cutout SETPOINT and the cutout is reset. See “Reset an Over-
Temperature Cutout” on page 31.
