Note: Please see the Reference Sensor Device entry on page 12 for the minimum device
requirements.
Temperature calibrations match the temperature display to the actual air temperature inside the
oven chamber. The actual air temperature is supplied by a reference sensor device. Calibrations
compensate for software drifts in the controller as well as deviations caused by the natural material
evolution of the sensor probe in the heated chamber space. Calibrate as often as required by your
laboratory or production protocol, or regulatory compliance schedule. Always calibrate to the
industry or regulatory standards required for your application.
A Suggested Calibration Set Up
3 ) The oven chamber door must
be closed and latched.
2 ) Place the sesnor probes in the oven with the probe
heads at least at least 2 inches (5cm) from the surface
of the shelving or walls to prevent heatsinking. Secure
with non-stick, heat-resistant tape.
If you are using only one thermocouple, place the
sensor probe head as close to the geometric center of
the oven chamber as possible.
Heat-resistant
non-stick tape
recommended
1 ) Introduce the reference device
thermocouple sensor probes into the
oven chamber through the access port.
Carefully place the port stopper over
the probe wires.
Probes may also be introduced through
the chamber door space. Use heat-
resistant, nonmarking tape to secure
the wires and seal any exterior gaps.
The door must close and latch fully.
4 ) The exhaust vent should be
closed to ensure an accurate
calibration
