to the menu item „Options“ using the arrow keys. Confirm
by pressing the button.
Select the menu item „Calibrate“ using the arrow keys
and confirm by pressing .
This menu item has to be unlocked. For that you have to enter the 4-digit serial
number of your humimeter PM4. You can find the serial number on the top right
edge of the display a short time after switching on the instrument, or on the sticker in
the battery slot.
Press the third button as long as the black bar stands on
the first digit of the serial number. After a waiting time of a
few seconds the device accepts the entered digit. Now
the other 3 digits have to be entered. When the 4-digit
number has been entered correctly (see picture), press
the button to confirm.
Hold the humimeter PM4 in one hand up in the air and
make sure that nothing stands behind the steel clamps
(distance min. 200 mm). Now press the second button
( ) with one finger.
The calibration procedure will take a few seconds. During
that time, the instrument has to be held up in the air and
the measuring field (steel clamps) must NOT be touched.
The device is ready when the shown picture on the right
disappears automatically.
