MEASU-REMENTS
1. Hold the probe in the area to be tested & allow
adequate time for readings to stabilize.
2. Press °F,'C, dew poi nt, WBT select Button to enter
select OF , "C, dew point Wet Bulb Measurement.
3. Read the Relative Humidity and Air Temperature, dew
point temperature wet bulb temperature.
NOTE:
Do not immerse the probe in liquid; it is intended for use in air
only.
Warning:
Don 't expose the sensor to direct sunlight ( in solation ).
Don't touch or manipulate the sensor.
6. BATTERY REPLACEMENT
If the sign " I':' +1 "appears on the LCD display, it indicates
that the battery should be replaced. Open the battery case
and replace the exhausted battery with new battery.
(1 x 9V
battery N
EDA 1604, 6F22 or equivalent).
