INSTRUMENT PREPARATION
Each meter is supplied complete with 4 each
1.5V AA batteries. Remove the back cover, un-
wrap the batteries and install them while paying
attention to their polarity.
Connect the RH probe to the 7-pin DIN socket
on the top of the meter and fasten the screw
tightly.
Note: HI 9065 has to be used with just one
probe (RH or temperature) at a time.
HUMIDITY MEASUREMENTS
Turn the meter on by pressing the ON/OFF key.
Press the RH key to display the RH % measurement. The symbol "H"
is displayed when measuring Relative Humidity (not for HI9160).
Using these hygrometers is simple. However, the recommendations
below should always be followed.
• The end of the humidity detector should be exposed to a current of
air moving at 0.5 m (20") per second or more.
• In the absence of air movement, the response can be accelerated
by moving the probe.
••
••
• The probe sensor must never come into contact with water or other
liquids.
If this should happen, or if condensation causes drops to form on
the surface of the humidity sensor, turn off the instrument and
wait until they have evaporated completely.
In order to accelerate the evaporation process, the humidity sensor
could be exposed to a current of air.
