Temperature Humidity Meter
Operation
Pressing S saves the present readings to a memory
location. L and the memory location number appear in
the display to indicate the readings have been stored. Press
W to return the display to the present reading. After all 99
memory locations are filled, each subsequent save
overwrites a memory location starting with the first.
To recall the readings from memory, press R. If the
memory location you are looking for is not already displayed,
press ▲ or ▼ until the desired memory location is displayed.
To return the Meter to normal operation, press R for two
seconds.
By default, relative humidity and ambient temperature are
displayed when a memory location is recalled. Pressing W
cycles through the Wet Bulb, Dew Point, and Ambient
temperatures stored in the memory location displayed.
To erase all 99 memory locations, simultaneously press S
and R for five seconds.

Automatic Power Off

To save battery life, the Automatic Power Off (APO) feature
can be used to turn the meter off after 20 minutes of no
activity. To enable or disable the APO feature, remove the
battery cover and position the APO switch to the desired
position. See Figure 1.
