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

Note: Save all packing materials until you are sure that the

instrument functions correctly. Any defective item must
be returned in the original packaging together with
the supplied accessories.

HI 9043 and HI 9044 are microprocessor-based thermometers
which allow temperature measurements using K-type thermo­couple probes. The non-linearity of the temperature probe is
linearized by the microprocessor.

Standard features include dual-level LCD for simultaneously
displaying of the highest and lowest measured temperatures,
display hold, selectable measurement unit (°C or °F) and resolution
which automatically switches from 0.1° to 1° for temperatures
above 200°C (400°F).

The meters are also provided with low battery detection and
BEPS (Battery Error Preventing System), which turns the unit
off when the battery is discharged avoiding erroneous read­ings caused by low battery level.

• HI 9043 is supplied complete with a 9V battery and

instruction manual.

• HI 9044 is supplied complete with HI 766E2 fixed

temperature probe, a 9V battery and instruction manual.

FACTORY RECALIBRATION

All Hanna thermometers have been accurately pre-calibrated
at the factory. It is generally recommended to have all
thermometers recalibrated at least once a year.

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

All Hanna Instruments meters are warranted for two years against de­fects in workmanship and materials when used for their intended purpose
and maintained according to instructions. Sensors and probes are war-
ranted for a period of six months.
This warranty is limited to repair or replacement free of charge.
Damages due to accidents, misuse, tampering or lack of prescribed mainte­nance are not covered.
If service is required, contact the dealer from whom you purchased the instru­ment. If under warranty, report the model number, date of purchase, serial
number and the nature of the failure.
First obtain a Returned Goods Authorization number from the Customer Ser­vice department, then return the instrument with the Authorization # included
along with shipment costs prepaid. If the repair is not covered by the war­ranty, you will be notified of the charges.
When shipping any instrument, make sure it is properly packaged for com­plete protection.

(*) Range may be limited by probe. The range of HI 9044

is limited to 900°C/1650°F by the fixed probe.

OPERATIONAL GUIDE

INITIAL PREPARATION

Remove the battery cover on the back of the thermometer.
Unwrap the supplied 9V battery, connect it to the battery clip
and reattach the cover.

Connect a K-type thermocouple probe to the meter.
Note: In HI 9044, the probe is fixed.
To switch ON, press the ON/OFF key on

the front of the meter.
The thermometer will carry out a self

diagnostic test routine, the LCD will
show all segments for a few seconds (or
as long as ON/OFF is held), followed
by the percentage indication of the
remaining battery life.

The thermometer then enters normal measurement mode.
If a temperature probe is plugged in, the meter displays the

measured temperature automatically switching to the resolu­tion suitable to the temperature range; i.e. 0.1° up to

199.9°C (399.9°F), or 1° above.
If no probe is plugged in, or if reading
is over-range, the display shows flash­ing dashes.
If a measurement is slightly over the range of the meter
specifications, the display flashes the closest full-scale value.
To switch the meter OFF, press the ON/OFF key.

MEASURING SCALE (°C/°F)

The instrument is factory set to the °C scale, but measurements can
be performed in either the Celsius or Fahrenheit scale.

Press the °C/°F button to select the desired
scale.

HOLD MODE

The HOLD function is activated by press­ing the HOLD key.

The measured temperature is held on the
display until HOLD is pressed again.

The "H" tag blinks on the display to
indicate the HOLD mode.

Note: Although the display is frozen, internally the meter

continues measuring and updating Hi and Lo values.

HIGH/LOW TEMPERATURES

The maximum and minimum tempera­tures are continuously monitored and
displayed on the lower portion of the
LCD.

Note: When reading goes over-range, the Hi and Lo values

display dashes until cleared.

CLEAR FUNCTION

Upon pressing the CLEAR key, the
High/Low values may be cleared at
any time during measurement and
the current reading is assigned to the
highest and lowest temperature val­ues.

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 areas could cause unacceptable interference to radio and
TV equipment, requiring the operator to take all necessary steps to correct interference.
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 voltage at the measurement surface
exceeds 24VAC or 60VDC.
To avoid damage or burns, do not perform any measurement in microwave ovens.

The instrument is powered by a 9 V battery and is provided
with the Battery Error Prevention System (BEPS), which turns
the unit off when a low battery signal is detected.

When the remaining battery level is
less than 10%, a warning symbol
blinks on the display to indicate a low
battery condition.

It is recommended to replace the battery as soon as the low
battery condition is detected.

Remove the cover on the meter's back by applying pressure in
the indicated direction. Unplug the rundown battery and
replace it with a new one.

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