WARRANTY

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
warranted 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

GENERAL DESCRIPTION

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 comes complete with a 9V battery and instruction
manual.

HI 9044 comes complete with HI 766E2 fixed 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.

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.

BATTERY REPLACEMENT

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.
