Calibrating the Humidity
If humidity calibration is needed, the following steps can be taken:
Locate the reference instrument’s temperature 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. Press the advance key until the
green display reads i.CAL (calibrate). Pressing the UP arrow will increase the Humidity
calibration offset by 1%. Pressing the down arrow will decrease the Humidity
calibration offset by 1%. Pressing and holding either button will rapidly scroll the
calibration offset. When finished, press the infinity key to return to the main menu.
Humidity calibration example
If the chamber temperature display reads 80% and the calibrated independent sensor
shows 83%, set the i.CAL 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 i.CAL would be -6.0%.
Calibrating Optional Chart Recorders
For calibrating the optional front and side mounted chart recorders, refer section 6
