FOR DISPLAYS WITH THERMISTOR PROBE ONLY
test leads here
reading should be 26 ± .5 ohms if not, adjust.
pot. range 0-34 ohms
BOTTOM OF TIME TEMP DISPLAY
TIME CALIBRATION
1. Be sure dip switch settings are proper.
2. Turn power on.
3. Turn conveyor on.
4. Place an object on the conveyor belt and time with a stopwatch, the elapsed time for the object to travel
through the oven (leading edge in to leading edge out).
5. Push in and hold the set button. (Discontinued on newer models)
6. Adjust time pot. (rear of display) so display agrees with your stop watch time.
7. Seal pot. with Glyptol or nail polish.
THERMISTOR PROBE REPLACEMENT
1. Shut off power at the main breaker.
2. Remove conveyor and fingers from oven.
3. Remove control compartment covers.
4. Disconnect the 2 yellow thermistor leads from terminals 9 and 10 on the rear of the time/temp. display.
