PRELIMINARY EXAMINATION

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

Note: Save all packing material until you

are sure that the instrument func­tions correctly. All defective items
must be returned in the original pack­ing with the supplied accessories.

GENERAL DESCRIPTION

HI 8564 and HI 93640 portable thermo-hygrom-

eters provide reading with high precision in a
very short time for both RH (Relative Humid­ity) and temperature.

HI93640 is a compact, portable and versatile
instrument to monitor relative humidity any­where. The built-in thin-film capacitance sen­sor assures accurate measurements from 5
to 95% RH with a resolution of 0.1%.

Note: The RH probe sensor must never

come into contact with water or
other liquids.

HI8564 is supplied complete with HI70601/2

RH probe, 9V battery and instructions.
HI93640 is supplied complete with probe sin-

tered cap, 9V battery and instructions.

OPERATIONAL GUIDE

CALIBRATION

INITIAL PREPARATION

Each meter is supplied complete with a 9V
battery. Slide off the battery compartment
cover on the back of the meter (see "Battery
Replacement" section), unwrap the battery and
install it.

To prepare HI 8564 for use, connect the RH
probe to the DIN socket on the top of the meter.

Turn the meter on by pressing the ON/OFF
button.

RELATIVE HUMIDITY MEASUREMENTS

• 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 happens, or if condensation causes
drops to form on the surface of the humidity
sensor, turn the instrument off and wait until
the liquid has evaporated completely. In order
to accelerate the evaporation process, ex­pose the humidity sensor to a current of air.

For HI93640 only: for a faster response,
remove the sintered cap. Whenever the probe
is to be used in a dusty or smoky environ­ment, the cap must be kept on at all times.

TEMPERATURE MEASUREMENTS

Simply press the °C or °F keys to display the
temperature reading.

When measuring temperature in degrees Cen­tigrade, "°C" is displayed.

For any problem in taking measurements, please
contact the nearest HANNA Customer Service
Department.

All HANNA hygrometers have been
precalibrated at the factory.
HANNA instruments® uses state-of-the-art
thermal humidity chambers for this purpose.
It is generally recommended to have all hy­grometers recalibrated at least once a year.

For an accurate annual recalibration, contact
your nearest Hanna Service Center.

You can also check the status of your HI8564
and perform a quick recalibration (with an
accuracy of ±5%) by using the Hanna mini­calibration chambers HI7101.

The kits are composed of two
thermally isolated chambers,
each one equipped with a

Na Cl

threaded cap and three bottles
containing the appropriate

Li Cl

11.1%

precalibrated saturated salts
to produce a known RH value.

Preparing the Calibration Solutions (HI 8564
only)

O

• Pour approximately 26 cc of

H

distilled water into a glass
container.

26 cc

• Immerse this container into a
bath of ice and water and
shake briefly.

Li Cl

• Slowly add the contents of
a HI 7111 bottle containing
LiCl into the glass container
while continuing to shake.

• When the salt has dissolved
completely, add all the con­tent of the second bottle of
HI 7111.

• Allow the solution obtained
to cool, and then pour it into
the chamber marked
"RH 11.1%", making sure
that no residue remains on
the walls of the glass con­tainer.

RH Calibration Procedure (HI 8564 only)

• Bring the calibration kit to a temperature of
approximately 20°C.

• Remove the cap from the
"RH 11.1%" chamber con­taining the LiCl solution and
insert the probe paying at­tention not to tip it into the

liquid.

• Remove the adhesive sticker which covers
the calibration trimmer access holes.

• Seal the chamber well when not in use, as
the LiCl solution is extremely hygroscopic
and tends to capture the humidity present in
the air causing the solution to expand in
volume and to overflow from the container.

BATTERY REPLACEMENT

Battery replacement must only take place in a
safe area and using the battery type specified in
this instruction manual.

FOR HI8564

When the battery becomes
weak, the "V" symbol is dis­played on the LCD to warn the
user.

In order to replace the bat­tery, simply slide off the cover
and replace the 9V battery
with a new one.

BATTERY

• Leaving the probe in the "RH 75.4%" cham­ber, adjust the low humidity trimmer until the
value of 75.4% is read.

H

• Now, the humidity calibration is complete.

Spare saturation salts are also available:
HI 7111/P (LiCl) for low range humidity, and
HI 7121/P (NaCl) for high range humidity.

12 13

FOR HI93640

When the battery becomes weak, the "V" sym­bol is displayed on the LCD to warn the user.

HI93640 is provided with the advanced BEPS
(Battery Error Preventing System) technol­ogy, that turns the meter off when a low
power condition is detected. It is recommended
to replace the 9V battery with a new one.

When the battery need to
be replaced, simply slide off
the battery cover and install

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 equipments, requiring
the operator to take all necessary steps to correct interferences.

In HI 8564 the trimmers are sensitive to electrostatic discharge.
It is recommended to use an antistatic screwdriver during calibra­tion.

Any variation introduced by the user to the supplied equipment
may degrade the instrument's EMC performance.

To avoid electrical shock, do not use these instruments when
voltages at the measurement surface exceed 24 Vac or 60 Vdc.

To avoid damages or burns, do not perform any measurement in
microwave ovens.
