PRELIMINARY EXAMINATION

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

Each thermometer comes sup­plied with a 9V battery and in­struction manual.

Note: Save all packing material
until you are sure that the instru­ment functions correctly. All de­fective items must be returned
in the original packing together
with the supplied accessories.

GENERAL DESCRIPTION

HI 945005 and HI 945007 are

microprocessor-based thermom­eters designed for food industry.

Temperature measurements are
performed by using interchange­able K-type thermocouple probes.

The non-linearity of the tempera­ture probe is linearized by the
built-in microprocessor, in order
to achieve high degree accuracy
and resolution. It also permits
accurate compensation for drifts
in the reference junction.

3

Standard features include:

• Interchangeable probes

(Hanna manufactures several
K-type thermocouple probes
for different applications; see
Acccessories section)

• Clear Liquid Crystal Display

• Possibility of switching be­tween the Centigrade and the
Fahrenheit scale

• HOLD function that freezes
the reading on the display (for
HI 945007 only)

• Low battery detection.

All these functions are easily ac­cessible through the keypad.

Self-explanatory symbols are
used to remind the user of the
operating mode or condition.

HI 945005 and HI945007 are ac­curately pre-calibrated at the fac­tory.

It is generally recommended to
have the thermometers recali­brated at least once a year.

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

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.

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.

OPERATIONAL GUIDE

INITIAL PREPARATION

Remove the battery cover on the
rear of your thermometer, unwrap
the battery and connect it to the
clip. Insert the battery in its com­partment and replace the cover.
(see "Battery Replacement" at
pag.9)

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

Your thermom­eter will carry out
a self diagnostic
test. The LCD
shows all the seg­ments at once.

After the test, the thermometer will
switch to the measurement mode.

If a temperature probe is plugged
in, the unit will display the tem­perature.
If the probe is not
plugged in, the
display will show
"Er".

To switch the
meter off, press
the ON/OFF key
twice.

7

MEASURING SCALE (°C/°F)

When the meter is turned on, it
automatically defaults to the °C
scale. Measurements can be per­formed on either the Centigrade or
the Fahrenheit scale.

To change the scale,
press the °C/°F key
once.

MEASUREMENT RESOLUTION

When switched on, the meters de­fault to 1 degree resolution.

Press the ON/OFF
key again to change
the resolution to

0.1°C (or 0.2°F).

HOLD MODE (for HI 945007 only)

The reading hold function is acti­vated by the HOLD key.

The temperature is frozen on the
display until the HOLD button is
pressed a second time.

The blinking symbol "M" appears
on the display when HOLD is acti­vated.

Press HOLD again to
return to the normal
operational mode.

8

LOW BATTERY DETECTION

When the battery
is low the user is
prompted by the
appearance of
the word "Eb" to
substitute the bat­tery.

AUTO-SHUT OFF

To save battery life, the meter
will switch off after 45 minutes.

The switch located in the bat­tery compartment enables this
feature. Remove the battery
cover and slide the switch to
the right. The thermometer's
auto-off feature will be disabled.
If the switch is to the left, the
meter will shut off automatically.

9

BATTERY REPLACEMENT

When the bat­tery is low the
user is warned
by the word
"Eb" on the
instrument's display.

Replace immediately the battery.

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

Remove the battery compartment
cover on the rear of the meter and
replace the 9V battery with a new
one. Make sure the battery con­tact is tight before replacing the
cover.

The meter will turn on automati­cally when a new battery is con­nected. You can turn it off by press­ing the ON/OFF key.
