Check Calibration of Temperature
IMPORTANT: Do not perform this procedure until the toaster has been
on for at least 45 minutes and temperature has stabilized. Do not use the
toaster during this 45 minute period.
1.
Place the rear of the bun board on top of the control box and place the rest of
the bun board on top of the platen.
NOTE: On dual platen toasters (411 & 416), the bun board is only
required for use on the top platen.
2.
On dual platen toasters, use
3.
Center the digital thermometer on the front edge of the platen. When the
corresponding LED on the control panel turns on, immediately record the
digital thermometer temperature reading.
NOTE: On dual platen toasters (411 & 416), perform step 2 on the lower
platen first, then the upper platen.
IMPORTANT: If the temperature reading on the platen is greater than
±3°C (±5°F) compared to the toaster temperature display, proceed with
step 3 to perform calibration. If temperature reading is within range,
toaster is functioning properly and does not require calibration.
4.
Enter the calibration mode by pressing and holding
A beep will sound and the LED next to the calibration symbol will turn on.
Release all buttons.
5.
Press and release
to select upper platen for calibration or
lower platen. Allow 10 seconds for the display to stabilize. The display will
show the measured platen temperature value with no offset.
NOTE: On dual platen toasters (411 & 416), calibrate each platen
separately.
6.
When the corresponding platen LED turns on, use
display temperature to match the reading recorded in step 3.
NOTE: Temperature can only be adjusted ±5°C (±9°F).
7.
Press
to store the new calibrated temperature and to exit calibration
mode.
IMPORTANT: After calibration is complete, allow one full heater on/off
cycle to allow the new calibrated temperature to stabilize.
