WARNING:
To avoid electric shock, do not operate the meter until the
battery cover is in place and
fastened securely.
NOTE:
: If your meter does not work properly, check the fuses and batteries
to make sure that they are
still good and that they are properly
inserted.
Calibration
A humidity calibration adjustment is located in the battery compartment.
1. Remove the battery door and move the battery to one side.
2. Place the humidity probe in a humidity chamber or humidity calibration
bottle and wait 20 minutes
3. Turn the meter on and turn the adjustment until the humidity reading
on the display agrees with the calibration source.
