Service Manual for Proofer Oven with Touch Screen Controls (TSC)
TEMPERATURE CALIBRATION PROCEDURE
The TSC Baking Center maintains temperature set
points at the center of the oven and proofer sections.
The TSC temperature sensors and controller PCB are
factory calibrated for an offset response to equate the
center chamber temperatures to the TSC displayed
values.
The temperature sensors are tight tolerance components
and the offset temperature response is factory programmed
in the TSC controller’s nonvolatile memory allowing
interchange of sensors, controller PCB’s, and/or control
software revision upgrades without temperature calibration
impact.
Field recalibration will only be required if the factory
settings were manually field modified. Should
temperature calibration of the unit be in question, the
following procedure in necessary to return the unit to
proper calibration.
Equipment:
FLUKE Model 54 Thermalmeter with two J-type
thermocouples or equivalent test equipment with +/-
1% tolerance
Procedure:
• Install a thermocouple in the center of the middle
rack of the proofer and oven; close the oven and
proofer doors.
• Turn on the TSC’s oven and proofer sections and
allow the unit to operate for a minimum of 15
minutes
• Enter the TSC screen button selections for
temperature calibration screens (press/hold
“OVEN”, enter PIN Code 1790, select oven or
proofer sensor)
• Monitor the TSC displayed temperatures until they
reach set points of 350ºF for the oven and 105ºF
for the proofer
• When the TSC displayed temperature falls 2ºF below
set points (348ºF oven and 103ºF proofer), adjust
the +/- buttons on the TSC screen until the TSC
displayed value matches the thermocouple meter.
• Repeat the process a minimum of two times with
a minimum of 15 minutes to stabilize after each
calibration adjustment.
