PRELIMINARY EXAMINATION
GENERAL DESCRIPTION
HI 9056 performs temperature measure-
ments using interchangeable K-type ther-
mocouple probes.
HI 9057 performs temperature measure-
ments 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 accu-
racy and resolution. Also the HI9056 accu-
rately compensates for temperature drifts in
the measurement circuit and the reference
junction.
HI 9056 has two built-in K-type probe con-
nectors. 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.

OPERATIONAL GUIDE
INITIAL PREPARATION
Remove the battery cover on
the rear of your thermom-
eter, unwrap the battery and
connect it to the clip. Insert
the battery into the compart-
ment and replace the cover.
To switch on, press ON/OFF
on the front of the unit.
The thermometer performs a
self diagnostic test. The LCD
dispalys all the segments at
once, to ensure none are
missing.
After the test, the thermometer will switch to
the measurement mode.
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 automati-
cally defaults to the °C scale. Measurements
can be performed on either the Centigrade
or the Fahrenheit scale.

Check the highest or lowest measured tem-
perature 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.
Release the key to resume normal opera-
tion.
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 tempera-
ture reading, i.e. both "HI" and "LO" will
have equal temperature readings.
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.

MEASUREMENT RESOLUTION
When switched on, HI 9056
and HI 9057 default to a 0.1
digit resolution (see specifi-
cations).
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.
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 measur-
ing process.
The values may be recalled or cleared at
any time during the measurement.

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.
LOW BATTERY DETECTION
To save battery life, HI 9056 and HI 9057
will switch off after 5 minutes.
When the battery is low the
user is prompted by the word
"BAT"to substitute the bat-
tery (see page 12).

SHOCKPROOF RUBBER BOOTS
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 col-
ors:
HI 710009 = blue colored
HI 710010 = orange colored
Select the proper color according to your
preference.
CALIBRATION
All Hanna Instruments thermometers have
been accurately pre-calibrated at the fac-
tory.
It is generally recommended to have all
thermometers recalibrated at least once a
year.
For an accurate annual recalibration, con-
tact 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. Re-
place the battery immedi-
ately.
Battery should only be replaced in a safe
area using the battery type specified in this
instruction manual (see page 17).
Remove the battery com-
partment cover on the rear
of the meter and replace
the 9V battery with a new
one. Make sure the battery
contact is tight before re-
placing the cover.
The meter may turn on au-
tomatically when a new bat-
tery is connected. You can
turn it off by pressing
ON/OFF.
