GENERAL DESCRIPTION
These microprocessor-based thermometers
allow temperature measurements using K-type
thermocouple probes. The non-linearity of the
temperature probe is linearized by the built-in
microcomputer. It also permits accurate compensation for drifts in the measurement circuit
and the reference junction.
Standard features include:
• display and clearing of maximum/minimum
temperature measurement
• reading hold
• memory entry (HI 9053 and HI 9055 only)
• low battery detection
Additional functions for HI 9053 and HI 9055
include:
• sound alarm with preset operating range
• display of constantly updated temperature
differential between stored and measured
values.
• selectable measurement range/resolution.
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.

INITIAL PREPARATION
Remove the battery cover on the rear of your
thermometer (see page 15).
Unwrap the battery. Connect the battery while
paying attention to the polarity and replace the
cover.
To switch on, press the ON/OFF
key on the front of the unit.
ON
OFF
Your thermometer will carry out
a self-test. The LCD shows a
full set of figures during the self-test.
After the test, the thermometer will switch to the
measurement mode.
Plug a K-type thermocouple probe in and the
unit will display the temperature.
Note: In HI 9044, the probe is directly con-
nected.
If a probe is not plugged in, the
display will show "Er".
To switch your thermometer off, press the
ON/OFF key again.
MEASUREMENT RANGE
When switched on, the instrument defaults to the high
range with resolution of
ON
OFF
1°C/1°F.
The measurement range may be changed to
a higher resolution range of 0.1°C or 0.2°F by
pressing the ON/OFF key again.
Note: Range switching causes all alarm
setting and memories to reset.
98
MEASURING SCALE - °C/°F (HI 9043 &
HI 9044 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
°C
°F
the scale, press the °C/°F button once.
HOLD MODE
The reading hold function is
activated by the HOLD (HI9043
HOLD
and HI 9044) or MEM HOLD
(HI9053 and HI 9055) key.
The measured temperature is
frozen on the display when this
key is pressed.
MEM
HOLD
A blinking "M" on display indicates the operation mode.
By pressing this key again, the
meter returns to its regular operation mode.
M
HI / LO FUNCTION
The maximum and minimum temperatures are
monitored throughout a continuous measuring
process.
The values may be recalled or
cleared at any time during the
HI LO
measurement.
Check the highest or lowest
measured temperature by
HI LO
pressing the respective HI or
LO key button. The appropriate display indicator, "HI" or
HI
"LO", will be displayed together with the value retrieved
from memory. Release the key to resume the
normal operation.
CLEAR FUNCTION
Erase the memorized highest
and lowest measured values
by pressing the CLEAR key.
CLEAR
Upon depressing the CLEAR
key, the present measurement
reading is assigned as the highest and lowest temperature in
memory, i.e. both stored temperature values are equal. The
"HI" and "LO" display indicators will blink twice to notify
HI
LO
user that the clearing process
is in progress.
ALARM (HI 9053 and HI 9055 only)
During the start up the alarm is
disabled. It may be enabled or
disabled again by pressing the
ENABLE
ENABLE key. Both the high
and low set points are by default set at 25°C or 77°F, conforming to the model.
The alarm is triggered when the measured value
is greater than the high set point or lower than
the low set point. In such an instance, the
corresponding graphics indicator blinks accompanied by a sound.
The buzzer may be turned off by pressing any
key except the ON/OFF key (by pressing ON/
OFF the alarm is disactivated and the scale
changes).
Reactivation is possible by turning the alarm off
and on again, i.e. by pressing ENABLE key
(note that the set point values will not be affected
by this action).
To set the alarm limits, press
SET
the SET key on the front panel.
1110
The flashing "HI •))" and "LO•))"
alarm indicators request the
HI •)
LO •)
)
)
user to opt for the set mode.
Select the HI key to enter the
set mode for high temperature
HI LO
point or the LO key for the low
temperature limit. If the HI key
is chosen, the low alarm indi-
HI
cator is switched off and the
"HI" indicator appears in the
top right corner of the LCD.
HI LO
Enter the set point value using
the * and + keys. Holding the
key down enables rapid change.
Exit from the high alarm limit
setting by pressing the SET
key for a second time. The user
SET
may now proceed to set the
low alarm limit or return to the
measurement mode by pressing the SET key again. The setting of low
temperature limit works in a similar manner.
MEMORY MODE (HI 9053 and HI 9055 only)
There are two modes of operation.
The first is the memory & hold
function which is activated by
the MEM HOLD key. The mea-
MEM
HOLD
sured temperature is captured
into memory and frozen on the
display when this function key
is pressed. The memory content will be overridden each
time the memory & hold function is activated. A blinking "M"
indicates the operating mode.
M
By pressing the same key, the
display freeze is released and
the meter returns to its regular
operating mode.
The next memory function key,
MR/∆M, serves two purposes:
- The first entry (by pressing
MR
∆M
this key once) enables the recall of the previously stored
temperature reading. If no data
is found, "_ _ _" will be displayed. In this mode of operation, the display indicator "M"
is kept static.
M
- The "∆M" display (by press-
ing MR/∆M twice) indicates the
constant updated discrepancy
∆M
between the memory content
and the measured value in a continuous measuring process. 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
memory value.
By pressing the MR/∆M key
once again, the user exits from
the memory mode.
MR
∆M
LOW BATTERY DETECTION
In order to avoid erroneous measurements being taken due to low voltage, the instrument
shuts itself down completely when the batteries
run low. The user is also
prompted to change them by
"Eb" on the LCD.

In order to avoid erroneous measurements being taken due to low voltage, the instrument
shuts itself down completely when the batteries
run low. The user is also
prompted to change them by
"Eb" on the LCD.
Battery replacement must only take place in a
non hazardous area using a 9V battery.
Remove the battery compartment cover at the
rear of the meter and replace the 9V battery with
a new one. Make sure the battery contact is
tight before putting the cover back.
The meter will turn on automatically when a new
battery is connected. You can turn it off by
pressing the ON/OFF key twice.
CALIBRATION
All Hanna Instruments 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 nearest Hanna Service Center.
