Temperature calibration (example)
If the chamber temperature display reads 40.0  C and the calibrated independent
sensor shows 40.3  C, set the temperature offset value to 0.3  C. If the calibrated
independent sensor shows 39.6  C, then the entered offset should be negative. In this
example the required offset to temperature would be -0.4  C.
Calibrating Humidity
If humidity calibration is needed, the following steps can be taken:
Locate the reference instrument’s humidity sensor in close proximity to the cabinet’s
geometric center. Be sure that the stabilization times described earlier have been
satisfied prior to performing this calibration.
A positive value will move the humidity ‘up’ and a negative value ‘down’. Press the
‘home’ button and verify the proper humidity is displayed.
Humidity calibration (example)
If the chamber temperature display reads 80% and the calibrated independent sensor
shows 83%, set the humidity offset value to 3.0%. If the calibrated independent sensor
shows 74  C, then the entered offset should be negative. In this example the required
offset to humidity would be -6.0%.
Calibrating CO2
If CO2 calibration is needed, the following steps can be taken:
Locate the reference instrument’s CO2 sensor in close proximity to the cabinet’s CO2
sensor. Be sure that the stabilization times described earlier have been satisfied prior
to performing this calibration.
A positive value will move the CO2 ‘up’ and a negative value ‘down’. Press the ‘home’
button and verify the proper CO2 is displayed. (See Temperature Calibration
Example.)
