Follow the instructions for the calibration solutions!
Calibration procedure
1) Unscrew the HL-20 humidity cage.
2) Screw the calibration device on to the HL-20.
3) Place calibration pads in the calibration cup. (Two pads per calibration process). Open the
calibration solution and pour into the calibration cup completely.
4) Insert the calibration cup into the calibration device completely.
5) Mounting of the retaining bracket / Connection to PC
Unscrew the battery cover and push the retaining bracket into the holes.
Connect the AC3006 connection cable to the device.
6) In a constant ambient temperature wait 2½ hours.
7) HL-20 calibration and adjustment procedure (general)
Connect the HL-20 logger to the PC with the AC3006 service cable. Launch HW4.
See the HW4 instruction manual E-M-HW4v3-Main_12 for further information on connecting
the logger to a PC.
The HL-20 adjustment procedure is carried out in two separate steps.
• Acquisition and saving of the calibration points
• Adjustment of the HL-20 on the basis of the saved calibration points

Acquisition and saving of humidity calibration points
In the device tree in HW4 select / HL-20 / “Probe Adjustment” / and then in the menu under
“Settings and Tools” select “%RH Reference”.
 Deactivate “Limit the adjustment range” for a standard adjustment.
In Adjust Humidity, enter the value of the humidity standard used at Reference Value and then
confi rm with Save Calibration Point.
As soon as “Save Calibration Point” is pressed, the values are applied in the table on the right side.
Repeat calibration with other humidity values.
Adjustment of the HL-20 based on the calibration points saved
To adjust the logger on the basis of the calibration data, you must press “Adjust” after entering
all desired calibration points.
