show the date previously memorized with the year blinking (shown as
the last 2 digits of the year, e.g. 95=1995).
Use the UP and DOWN keys to select the year.
When the correct year is selected, press the RANGE key once and the
month will start blinking.
Select the correct month by pressing the UP or DOWN keys.

RELATIVE HUMIDITY MEASUREMENTS
Operations with the HI 9161 and HI 91610 are very simple.
• For accurate measurements, the RH sensor 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 any other liquid. If this happens, or if condensation causes
drops to form on the surface of the humidity sensor, the instru-
ment must be turned off until moisture has completely evaporated.
To accelerate the evaporation process, expose the humidity sensor
to a current of air.
For any problem in taking measurements, please contact your dealer
or the nearest HANNA Customer Service Center.
TEMPERATURE MEASUREMENTS
The HI 762L/2 temperature probe supplied with theinstrument is a
liquid/general purpose probe with 2 m (6.6') cable.
Simply plug the probe into the socket located on the top of the meter.
If continuous monitoring of temperature is needed, keep the probe
attached to the meter at all times.
To view either the RH% or temperature read-
ing on the display, press RANGE. The reading
will appear without decimal digit when shown
on the secondary display. The temperature
range on the secondary display goes from 0
to 99°C (or °F).
If the temperature exceeds this range, "--"
will appear indicating that the secondary
display is unable to show the reading.
If no probe or test plug is connected, the
meter will display and print "----" to alert the
user. This could also indicate that the probe
cable is damaged.
HANNA offers a wide range of temperature probes to meet all
application requirements. HANNA HI 762 probe series use highly
sensitive thermistor sensors to provide great accuracy and fast response
(see "Accessories" section for a complete list).
