Note:
Performing a temperature display calibration requires a temperature reference device. Please
see the
Reference Sensor Devices entry
on page 8 for device requirements.
Temperature calibrations are performed to match the incubator temperature display to the actual air
temperature in the incubation chamber. The actual air temperature is supplied by a calibrated
reference device. Calibrations compensate for long-term drifts in the microprocessor controller as
well as those caused by the natural material evolution of the sensor probe in the heated and chilled
incubation space. Calibrate as often as required by your laboratory or production protocol, or
regulatory compliance schedule. Always calibrate to the standards and use the calibration setup
required by your industry requirements or laboratory protocol.
Suggested Calibration Setup
Heat-resistant, non-stick tape recommended
1.
Introduce the reference device
thermocouple probe through the
chamber lid space.
2.
Position the sensor probe head
as close as possible to the
geometric center of the chamber,
with the probe head at least 2
inches (51 mm) from the shaking
platform to prevent heatsinking.
with the probe head hanging down
from the chamber ceiling.
Do not
attach the probe to the shaking
platform.
Secure the probe head in
position using the non-stick tape.
3.
After securing the probe head in
position, carefully close the
chamber lid. Use non-stick tape to
seal any gaps created by the probe
wires.
4.
The incubator chamber lid must be
closed securely. Failure to do so will
prevent an accurate calibration.
