ALIBRATE THE
T
EMPERATURE DISPLAY
Note:
Performing a temperature display calibration requires a temperature reference device. Please
see the Reference Sensor Device entry on page 6 for the device requirements.
Note:
Each SMI12 incubation chamber must be independently calibrated to its temperature display.
Temperature calibrations are performed to match an incubator temperature display to the actual air
temperature inside the incubation chamber. The actual air temperature is supplied by a calibrated
reference device. Calibrations compensate for long-term drifts in the incubator microprocessor
controller as well as those caused by the natural material evolution of the sensor probe in the heated
incubator 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.
A suggested calibration setup
4. The incubation chamber door must be closed
and latched. Failure to do so will prevent an
accurate calibration.
2. Position the sensor probes in the incubation
chamber with the probe heads at least at least 2
inches (51mmm) in diagonally from the chamber
corners. The probe heads should be at least 2
inches (51mm) above the shelving to avoid heat
sinking. Place 1 probe head as close as possible to
the geometeric center point of the chamber.
Secure all probes in place with non-stick, heat-
resistant tape.
If using a only single thermocouple, place the
sensor probe head as close as possible to the
geometric center of the incubation chamber.
Heat-resistant
non-stick tape
recommended
1. Introduce the reference device
thermocouple sensor probes into the
incubation chamber through the access
port on the right side of the incubator.
3. After securing the probe heads in position,
carefully place the access port stopper in the
port over the probe wires. Use non-stick tape to
seal any gaps created between the stopper and
the port by the probe wires.
