1 Make sure UHC is clean and at proper operating temperature.
2 Read and compare temperature of top heater plate.
The button end of the probe is placed against the plate being measured.
UHC heater plates are hot.
3 Read and compare temperature of bottom heater plate.
The pyrometer is showing a temperature within five degrees of the cabinet display, an acceptable margin.
The UHC-P narrow doesn’t display setpoint, only plate temperatures.
Use the Palm Pilot to recalibrate the cabinet, following steps in the operator’s manual.
The UHC-P software in the Palm Pilot is used to recalibrate the cabinet.

The temperature of all the heater plates is tested against the reading of the pyrometer.
Tip: Read and compare temperatures one slot at a time during low-volume periods.
