8. Calibration
The calibration of a cabinet can be done in two different ways:
Exchanging the sensor. According to the effective ISO specifications it is recommended to
change the sensor every 12 to 24 Months by a new, calibrated sensor (incl. a calibration
report).
Calibrating / adjusting the offset value of the digital display.
Remark:
Before calibrating, first a reference value must be determined with an additional calibrated
hygrometer (i.e. the cabinet atmosphere must be measured). Attention: do not measure the humidity
during the recycling mode of the drying unit!
Instruction
1.
Unplug the main Power Plug.
2.
Press both adjustment buttons (“UP” and “DOWN”), and keep pressed while plugging the
main power plug again. During this time the LED display is blank.
3.
Press “ON / OFF”, the current offset value will be shown on the LED display.
4.
Press the “SET” button to start the calibration, the current offset value on the LED display will
begin to flash.
(To end the calibration program and start the operation of SUPER DRY, press the “ON/OFF”
twice)
5.
Adjust the humidity offset point with the “UP” or “DOWN” button:
“UP” increases, “DOWN” decreases the
offset value
. After finishing
adjustments press the “SET” button again. The new offset value will
be shown on the LED display.
E.g. the humidity display on the digital control panel is 3%RH, and the actual hu-
midity inside SUPER DRY is 1%RH, so set the offset value to 2 (3-1=2)
6.
By pressing the “ON/OFF” button once, SUPER DRY will return to the standby condition.
To operate SUPER DRY, press the “ON/OFF” button a second time.
Press the “SET” button and follow the above instruction from point 3 to restart the calibration.
* The Temperature Display Light on the digital control panel will be on during the process from item
2 to item 3.
