GENERAL DESCRIPTION
HI 9040, HI 9041, HI 9050 and HI 9051 are microprocessor-based
thermometers which allow temperature measurement using a calibrated thermistor probe. The temperature probe is linearized by the
built-in microprocessor.
HI 9041 has been specifically designed by Hanna Instruments for use
in the food industry.
Standard features include:
• display and clearing of maximum/minimum temperature measurements
• memory entry and hold
• low battery detection
Additional functions (HI 9050 and HI 9051) include:
• sound alarm with preset operating range
• display of constantly updated temperature differential between
stored and measured values.
These functions are easily accessible through the splash-proof membrane keypad. Self-explanatory symbols are used to remind the user
of the operating mode or condition.

OPERATIONAL GUIDE
MEASURING SCALE - °C/°F (HI 9040 only)
The meter automatically defaults to the °C
scale when turned on. Measurements can be
performed in either the Centigrade or Fahrenheit scale. To change the scale, press the
"°C/°F" button once.
°C
°F
HOLD MODE (except for HI 9041)
The hold function is activated by either the
HOLD (HI 9040) or HOLD/MEM (HI 9050
and HI 9051) key. The measured temperature is frozen on the display when this key is
pressed. A blinking "M" on display indicates
the operational mode. By pressing the key
one more time, the meter returns to measurement mode.

HI/LO FUNCTION (except for HI 9041)
The maximum and minimum temperatures
are continuously monitored. The contents may
be recalled and/or cleared at any time during
measurement.
Enquires of the highest or lowest temperature
measured may be made by pressing and holding down the respective HI or LO key. The
appropriate display indicator, "HI" or "LO",
will light up together with the value retrieved
from memory. Release the key to resume
normal operation.

CLEAR FUNCTION (except for HI 9041)
Upon pressing the CLEAR key, the memory is
cleared and the present measurement reading is assigned to the highest and lowest
temperature memories, i.e. the temperature
reading is equal for both memories. The "HI"
and "LO" display indicators will blink twice to
alert the user.

ALARM (HI 9050 and HI 9051 only)
During the start-up, the alarm is disabled. It
ENABLE
may be enabled or disabled again by pressing the ENABLE key. Both the high and low
setpoints are by default set to 25°C (or 77°F).
The alarm is triggered when the measured
value is greater than the high setpoint or lower than the low setpoint.
In such an instance, the corresponding graphics indicator blinks accompanied by an audible sound. The beeper may be turned off by
pressing any key except the ON/OFF key (The ON/OFF key will turn
the unit off and clear the memory). It will automatically be reactivated once the alarm condition is cleared. Reactivation is also possible
by turning the alarm off and on again. Note that the setpoint values
will not be affected by the on-off action.
To set the alarm limits, press the SET key. The flashing "HI •))" and
"LO •))" alarm indicators request the user to select the limits.
SET
HI •))
LO •))
Press the HI key to enter set mode for high
temperature point or the LO key for low temperature limit. If the HI key is chosen, the low
alarm indicator is switched off leaving the "HI"
indicator blinking with its graphics indicator
held static. Enter the setpoint value with the !
and " keys. Holding the keys down enables
rapid change. Exit from the high alarm limit
setting by pressing the SET key for a second
time. The user may now proceed to set the low
alarm limit or return to the measurement mode
by pressing SET again. The setting of low temperature limit works in a similar manner. In
case of improper setpoint entries, a continuous
false alarm beeper will sound.

display when this key is pressed. The previously memorized temperature will be overridden in this case. A blinking "M" on the
display indicates the operating mode. Press
the MEM/HOLD Key again to revert back to
M
regular operating mode.
The next memory function key, MR/∆M,
MR
serves two purposes:
∆M
- The first entry enables recall of the latest
memorized temperature. If no data is
found, "---" will be displayed and the
subsequent function will be aborted on
the next key entry. In this mode, the
"M" indicator also appears on the bottom right corner of the LCD.
- The "∆M" symbol indicates the constantly
updated difference between the memory
∆M
content and the current temperature being measured. Calculation is performed by subtracting the
measured value from the memory content, i.e.:
∆M = (M-T)
where
M = memory content
T = measured temperature
A negative result therefore represents a lower memorized value.
Press the MR/∆M key once again to exit this mode.
While in the memory mode, other functions such as HI, LO and
Alarm remain active.
LOW BATTERY DETECTION
The instrument stops operating when a low
battery condition is detected. The user is
warned by "Eb" displayed on the LCD.
MEMORY MODE (HI 9050 and HI 9051 only)
There are two modes of operation.
The first is the Memory & Hold function which is
activated by the MEM HOLD key. The measured
temperature is memorized and frozen on the

CALIBRATION
All Hanna thermometers have been accurately pre-calibrated at the
factory.
It is, however, recommended to have all thermometers recalibrated at
least once a year. For an accurate annual recalibration, contact your
nearest Hanna Service Center.
Hanna 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 unit 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 ±0.4°C
HI 765000C Calibration key, 0.0°C ±0.4°C
HI 765070C Calibration key, 70.0°C ±0.4°C

BATTERY REPLACEMENT
The instrument stops operating when the low
battery signal is detected. The user is warned
of this by the code "Eb".
Battery replacement should only take place
in a non-hazardous area using an alkaline 9V battery.
Remove the battery cover at the rear of
the meter and replace the 9V battery with
a new one. Press in the battery contacts to
make sure they are properly inserted before replacing the cover.

HANNA INSTRUMENTS TEMPERATURE PROBES
Hanna Instruments offers a wide range of probes to meet all your
requirements from liquids to air and penetration. These probes use
highly sensitive thermistor sensors which provide greater accuracy,
faster response and a temperature range that is superior to conventional thermistor probes.
All Hanna temperature probes are supplied pre-calibrated from the
factory and are ready to be used with your meter. The probes are
easily to your meter with a standard connector.
Completely interchangeable, these probes make it possible for you to
switch from one to another without wasting time and money going
through time-consuming and tedious calibration procedures.
The probes are available in different colors to avoid cross contamination during testing:
HI 765A
Air probe, with 1 m (3.3') cable and white handle
HI 765A/10 Air probe, with 10 m (33') cable and white handle

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 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 60VDC.
To avoid damage or burns, do not perform any measurement in microwave ovens.
In particular cases the meters could turn off. In these cases they can be turned on by pressing the ON/OFF key.
