Recommendations for Users

Before using these products, make sure that they are entirely suitable for the environment in which they are used.
Operation of these instruments in residential area could cause unacceptable interferences to radio and TV
equipment, requiring the operator to take all necessary steps to correct interferences.
Any variation introduced by the user to the supplied equipment may degrade the instruments' EMC performance.
To avoid electrical shock, do not use these instruments when voltages at the measurement surface exceed 24VAC or
60 VDC. To avoid damages or burns, do not perform any measurement in microwave ovens.

Remove the instrument from the packing material and examine it carefully to make sure
that no damage has occurred during shipment. If there is any damage, notify your
Dealer.

Both models come supplied with:

• HI 70602 RH/temperature probe

• 9V battery

• instruction manual.

Note: Save all packing material until the instrument has been observed to function

correctly. Any defective item must be returned in its original packing.

GENERAL DESCRIPTION

HI 9564 and HI 9565 are portable thermo-hygrometers for measurements of Temperature
and Relative Humidity. HI 9565 also shows the dewpoint calculated from the measured
Temperature and Relative Humidity.

The instruments are housed in a rugged, water-resistant casing for maximum protection
against effect of humidity and condensation.

The RH/temperature probe is a “smart probe” which contains the sensors, electronic sensor
drive circuitry and memory to store the calibration information. This allows interchange­ability between probes and meters without recalibration.

Note: The RH probe sensor must never come into contact with water or other liquids.

Hanna Instruments reserves the right to modify the design, construction and appearance of its products
without advance notice.

OPERATIONAL GUIDE

• The meter is supplied complete with a 9V battery. Remove the battery compartment
cover on the back of the meter and install the battery while paying attention to its
polarity.

• Connect the probe to the connector on the top of the instrument and switch ON by
pressing the ON/OFF key.

Note: It is not recommended to install or remove the probe while the meter is on.

• At start-up the instrument displays all LCD segments for a few seconds (or as long as the
ON/OFF button is held), then it shows the current RH measurement.

• To switch the display to show temperature, dewpoint (HI 9565 only) or return to RH
reading, press RANGE.

• Both models are provided with three slide switches located in the battery compartment
which allow the user to select the following options:

1. °C/°F unit for temperature and dewpoint

(HI 9565 only) readings;

2. disable/enable (20 minutes) auto-off

feature;

3. disable/enable keypad acoustic signal.

To access these features, remove the battery cover on the back of the meter and extract
the battery. Select the desired settings, insert the battery and close the cover.

RH CALIBRATION

The RH calibration is a single point procedure (offset).

• To enter calibration: from normal mode press and hold the CAL
button for approx. 5 seconds, until the display shows the “CAL”
message. Release the button. The meter will display “OFS” and
then flash the default value (60% RH) for calibration.

ERROR MESSAGES

All modes of operation

• Blinking values denote indicative readings. This will occur for the RH display and dewpoint
display if the measured temperature is less than 0°C or greater than 60°C.

• A blinking full scale value means that the reading is out of range.

No data currently available to be displayed. If dashes are shown in
MIN/MAX mode, press CLEAR to reset the values.

No probe connected or invalid calibration data retrieved from the probe.
The meter continues checking probe until error condition is corrected.

Error in temperature measurement: the reading is extremely over
range or the probe is damaged.

Error in RH measurement: the sensor is wet or the probe is
damaged.

Calibration mode, upon pressing CAL to accept value

The measured RH is greater than the set value by more than 9%
RH.

The measured RH is lower than the set value by more than 9% RH.

Note: A blinking full scale value means that the reading is out of range.

• To freeze the current measurement on the
LCD, press HOLD. The “H” tag will blink and
the meter continues measuring and updating
the min/max values internally. Press HOLD to
return to normal mode.

Note: Even in Hold mode, the user can still scrow through the channels with RANGE, to

show the status of the meter when HOLD was pressed.

Note: The CLEAR and CAL keys are disabled when the meter is in Hold mode.

• To display the current minimum (or maximum) value for the current measurement
range, while in normal or hold mode, press and hold the MIN (or MAX) key. The
“MIN” (or ”MAX”) tag turns on while the corresponding button is pressed. The
display will return to normal mode 1 second after releasing the button.

• To reset the min/max values to the current
measurements, press CLEAR. This function
clears the RH, temperature and dewpoint
(HI 9565 only) values together. The display
will show the “CLr” message and then return to normal mode.

• To turn on/off backlighting (HI 9565 only), press LIGHT. The
backlight automatically shuts off after 1 minute without button
use.

• To switch the meter OFF, press the ON/OFF key.

• Measure the actual RH value with a reference RH meter
and then use the UP & DOWN arrow keys to match that
reading. The value can be set within the 30 to 90% RH
range.

Note: Hold the arrow keys to advance the display at a faster rate.

• Wait until the hourglass symbol (stability indicator) on the LCD turns off, then press
CAL to accept the value.

If all parameters are valid, the display shows the “Str”

(Store) message for a few seconds and then returns to
normal mode. If a parameter is not valid, an error
message will be displayed (see “Error messages” section).

Note: Pressing CAL key while the hourglass symbol is on will not accept calibration.

• For successful calibration, the measured temperature must be within 15 to 35°C (59 to
95°F), and the displayed set value must be within ±9% RH of the actual measured
value by the probe. When the CAL key is pressed to accept the value, the meter
automatically verifies all parameters.

• To exit calibration mode without saving any values, press
and release the ON/OFF button. The meter will display
“ESC” and then shut off. Press ON/OFF to power the meter
on and return to normal mode with the previous calibration data.

• To clear any previous offset calibration value, while in calibration mode, press and hold
the ON/OFF key and then CAL. The meter will display the “CLr” message and then
“Str”, before returning to the normal mode.

Note: If a weak battery is detected or the probe is removed during calibration, the meter

will abort the calibration procedure and shut off.

The calibration temperature is too high.

The calibration temperature is too low.

BATTERY REPLACEMENT

The BEPS (Battery Error Prevention System) recognizes two different low battery levels.

1. Weak battery: at start-up the display shows the "Cb"

(Change battery) message for a few seconds, then enters
normal operation together with a blinking battery symbol.

The meter can still work for a few hours, but it is recommended to replace the
battery soon.

2. Dead battery: at start-up the display shows the "Eb"

(Error battery) message for a few seconds, then the meter
shuts off to avoid erroneous readings. Replace the bat­tery.

In order to replace a rundown battery, remove the battery
compartment cover on the back of the meter and replace the
battery with a new one, while paying attention to the correct
polarity.

Battery replacement must only take place in a non hazard­ous area using a 9V alkaline battery.
