HI 9056 performs temperature measurements using interchangeable K-type thermocouple probes.
HI 9057 performs temperature measurements with different types of thermocouples
(K - J - T). This meter is equipped with a key
that switches range from K-type to J-type or
T-type thermocouples.
The non-linearity of the temperature probe
is linearized by the built-in microprocessor,
in order to achieve a high degree of accuracy and resolution. Also the HI9056 accurately compensates for temperature drifts in
the measurement circuit and the reference
junction.
HI 9056 has two built-in K-type probe connectors. By simply pressing a button, the
meter switches between the two readings on
the display. A "∆T" button will display the
difference between the two probe readings.
32
Standard features include:
• Interchangeable probes
• Clear Liquid Crystal Display
• Two year Warranty
• Possibility of switching between the Centigrade and the Fahrenheit scale (for
HI 9057 only)
• HOLD function that freezes the reading
on the display (for HI 9057 only)
• HI-LO memory recall function (for HI 9057
only)
• Low battery detection.
All these functions are easily accessible
through the keypad.
Self-explanatory symbols are used to remind the user of the operating mode or
condition.
Hanna manufactures several K-type thermocouple probes for different applications.
See pages 14-17 for more details.

If a temperature probe is plugged in, the
unit will display the temperature.
If the probe is not plugged
in, the display will show
"----".
To switch your thermometer off, press ON/
OFF again.
MEASURING SCALE (°C/°F) (HI 9057
only)
When the meter is turned on, it automatically defaults to the °C scale. Measurements
can be performed on either the Centigrade
or the Fahrenheit scale.
76
To change the scale, press °C/°F once.
°C
°F
°F
Check the highest or lowest measured temperature by pressing the respective HI or
LO key. The appropriate display indicator,
"HI" or "LO", will light up together with the
value retrieved from memory.
MEASUREMENT RESOLUTION
When switched on, HI 9056
°C
and HI 9057 default to a 0.1
digit resolution (see specifications).
These instruments automatically change the
resolution to 1 degree when the measured
temperature is higher than 999.9°C.
In HI 9056, when the tem-
perature is lower than
999.9°C it is possible to
change the resolution by
pressing the 0.1/1 key.
HOLD MODE (HI 9057 only)
The reading hold function is activated by
the HOLD key.
To freeze the measured temperature on the
display, press and hold the HOLD key.
"HOLD" is displayed when this key is pressed.

CLEAR HI-LO FUNCTION (HI 9057
only)
By pressing HI and LO simultaneously the
present measurement reading is assigned in
memory as the highest and lowest temperature reading, i.e. both "HI" and "LO" will
have equal temperature readings.
HOLD
As soon as the HOLD key is released, the
meter returns to normal operational mode.
HI-LO FUNCTION (HI 9057 only)
Maximum and minimum temperatures are
monitored throughout a continuous measuring process.
The values may be recalled or cleared at
any time during the measurement.
MEMORY FUNCTION (HI 9056 only)
The memory & hold function is activated by
MEM HOLD. The measured temperature is
stored in memory and frozen on the display
when this function key is pressed and held.

The memory value will be overridden each
time the memory & hold function is activated. A blinking "MEM" on display indicates the operating mode.
Press and hold MR to recall previously stored
temperature reading. In this mode of operation, the display indicator "MEM" is shown.
TEMPERATURE DIFFERENCE (HI 9056 only)
The difference between the temperature
measured by the two probes can be dis-
played by simply pressing ∆T. A "∆" will
appear on the left-hand of the display to
indicate this function.

If no data is found, "----"
will be displayed.
THERMOCOUPLE TYPE SELECTION
(HI 9057 only)
By pressing KJT the user is allowed to set
the thermometer according to the connected
thermocouple type, and the related symbol
will be displayed, i.e.:
K for K-Type, J for J-Type, T for T-Type.

PROBE INPUT SELECTION (HI 9056 only)
When switched on, the instrument automatically shows
the temperature measured by

Probe 1 and a "K1" appears
on the LCD display.
To view the input temperature of Probe 2,
press T1/T2 and "K2" will be displayed.

CALIBRATION
SHOCKPROOF RUBBER BOOTS
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.
BATTERY REPLACEMENT
When the battery is low
the user is warned by the
"BAT" indication on the
instrument's display. Replace the battery immediately.
Battery should only be replaced in a safe
area using the battery type specified in this
instruction manual (see page 17).
Remove the battery compartment cover on the rear
of the meter and replace
the 9V battery with a new
one. Make sure the battery
contact is tight before replacing the cover.
The meter may turn on automatically when a new battery is connected. You can
turn it off by pressing
ON/OFF.
These rubber boots are specially made to
prolong the life of your instruments and to
prevent damage due to accidental falls.
They and are available in two different colors:
HI 710009 = blue colored
HI 710010 = orange colored
Select the proper color according to your
preference.
