Humimeter BLL User Manual

User manual for test block
General
The surface of the test block has to be free from dust, dirt, oil and dampness, and it must not
be scratched. The ideal test temperature was defined at 23°C. However, a test temperature
between 20°C and 26°C is sufficient. Air humidity has to be between 30% r.h. and 80% r.h.
The device as well as the test block have to be stored in the same surrounding for some time
before testing. If you do not comply with these specifications this may lead to deviations.
This manual declares the test of following devices:

humimeter BLL

humimeter FL1 & FL2

humimeter FLH

humimeter BLW

humimeter BL2
Test procedure:
humimeter BLL & BL2 insertion probe:
Switch on the device and change to the calibration curve level using the very left button.
Select the calibration curve „test block" using the arrow keys. Put side „1" of the test block
onto the measuring head as shown on the picture below. Now your device should show the
value 22,0% (+/-1,0%). If the measuring value is blinking in grey, the value is beyond the
stated specifications (please read „possible reasons for errors). If the measuring value is
shown in black, the value is o.k. and you can go on with the procedure on the second side in
the same manner. Now the display should show the value 41,0% (+1,0%, -1,5%) in black.
