Getting Started
1.
Remove the plastic tab sticking out of the battery tray. This
will activate the display and begin the collection of readings.
2.
Mount the unit onto the desired location. The best location is
in a central area where the airflow to the unit will not be
blocked. To attach the magnet mount to a surface, first ensure
that the surface is clean and free of any dust or other debris.
For best results, use an alcohol swab to clean the area where
the adhesive will be applied. Remove the backing paper from
the adhesive disc on the back of the magnet and apply firm
pressure to hold the magnet in place for about 30 seconds.
Allow the adhesive to dry for at least 24 hours before attaching
the hygrometer.
Min/Max Recording and Display
The Caliber IV
tm
will record the minimum and maximum values
for both humidity and temperature. To view the maximum
values, press the Min/Max/Clear button one time. The
maximum value will be displayed with the word MAX at the top
right of the temperature reading.
To view the minimum values, press the Min/Max/Clear button
two times. The minimum value will be displayed with the word
MIN at the top right of the humidity reading.
To reset the values, while viewing either the MAX or MIN value,
press and hold the Min/Max/Clear button for about 5 seconds.
When the display shows empty values, that MAX or MIN value
has been reset. Both values are reset independently. Removing or
replacing the battery will also reset both the minimum and
maximum values.
