MAX / MIN Feature
When the meter is turned on it begins keeping track of the highest (Max) and lowest (Min)
temperature and relative humidity readings. To view these readings at any time, press the
MAX/MIN key.
The maximum temperature and humidity readings will appear along with the MAX display
icon. Press the MAX/MIN key again to view the minimum temperature and relative
humidity readings. The minimum temperature and humidity readings will appear along with
the MIN display icon.
Press MAX/MIN key again to exit this mode.
To Clear the MAX/MIN readings, press the CLEAR key once with the MAX or MIN value in
the display. The meter will clear the existing records and begin storing new MAX/MIN
records. Note that the MAX/MIN records are automatically cleared when the meter is
turned off.
Comfort Level Feature
The Comfort Level display ('Wet', 'Dry', or 'Comfort' icons) will appear at the center of the
LCD.
For humidity measurements below 40%, the meter displays the 'DRY' icon. This region of
humidity can be harmful to furniture and other wood products where splitting and cracking
could occur after prolonged exposure. Electronic equipment is also at risk in this region
from static electricity.
For humidity measurements above 70%, the meter will display the 'WET' icon. Humidity
above 70% is not considered safe for dwellings or work areas where mold can form and
wood can swell and warp. In addition, sensitive objects such as artwork, musical
instruments, and paper documents can be damaged by high moisture.
Humidity between 40% and 70% is the most comfortable environment for people, furniture,
paper, artwork, etc. In this region the meter displays the 'COMFORT' icon.

When the low battery indicator appears (the letter 'X' over the battery symbol), replace the
two (2) 1.5V 'AA' batteries thusly:
