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.

Standard features include:

• Interchangeable probes

• Clear Liquid Crystal Display

• Two year Warranty

• Possibility of switching between the Cen-

tigrade 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.

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.

FUNCTIONAL DESCRIPTION AND

SPECIFICATIONS OF HI 9057

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.

°C

HOLD

To change the scale, press °C/°F once.

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.
