GENERAL DESCRIPTION
HI 9040 is a hand-held microprocessor-based thermometer
which allows fast and accurate temperature measurements,
using a calibrated thermistor probe. The temperature probe
is linearized by the microprocessor.
The meter is also provided with low battery detection and
BEPS (Battery Error Preventing System), which turns the
unit off when battery is discharged avoiding erroneous
readings caused by low battery level.
HI 9040 features include a dual-level LCD for simultaneously
displaying of maximum and minimum measured temperatures, °C/°F selection button and HOLD function.
Each meter is supplied complete with a HI 765BL thermistor
probe, a 9V battery and instruction manual.

OPERATIONAL GUIDE
Note: When reading goes over-range, the Hi and Lo values
display dashes until cleared.
FACTORY RECALIBRATION
TEMPERATURE PROBES & ACCESSORIES
INITIAL PREPARATION
Remove the battery cover on the back of the thermometer.
Unwrap the supplied 9V battery, connect it to the clip and
reattach the cover.
Connect the temperature probe to the connector on the top
of the meter.
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.
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 thermometer 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 in the
lower portion of the LCD.
CLEAR FUNCTION
Upon pressing the CLEAR key, the
current reading is assigned to the
highest and lowest temperature values. The High/Low values may be
cleared at any time during measurement.
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.
All Hanna thermometers have been accurately pre-calibrated
at the factory.
It is recommended to have all thermometers recalibrated at
least once a year. For an accurate annual recalibration,
contact your nearest Hanna Service Center.
Hanna Accuracy Test Plugs provide a quick and easy way
to test the meter's accuracy by simply connecting these Test
Plugs to the probe connector of the meter. If the reading
differs by more than ±0.4°C (±0.8°F) from the Test Plug
value, the meter is due for recalibration. Choose the Test
Plug closest to your measurement range to best suit your
needs:
HI 765-18C Calibration key, –18.0°C
HI 765000C Calibration key, 0.0°C
HI 765070C Calibration key, 70.0°C
HI 765-004F Calibration key, –0.4°F
HI 765032F Calibration key, 32.0°F
HI 765158F Calibration key, 158.0°F
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.
Hanna offers a wide range of probes to meet your needs
with air, liquid, penetration and surface measurements.
All Hanna temperature probes are pre-calibrated at the
factory and ready-to-use. These interchangeable probes
make it possible to switch from one probe to another
without requiring recalibration.
Hanna probes are also available in different handle colors
to avoid cross contamination during testing.
