PRELIMINARY EXAMINATION
Remove the instrument from the packing ma-
terial and examine it carefully to make sure
that no damage has occurred during ship-
ment. If noticeable damage is found, notify
your Dealer.
Note: Save all packing material until you are
sure that the instrument functions cor-
rectly. All defective items must be re-
turned in the original packaging to-
gether with the supplied accessories.
GENERAL DESCRIPTION
HI 9060, HI 9061 and HI 91541 waterproof por-
table thermistor thermometers are very easy
to use in any field where high humidity levels
and dust could effect the performance of a
conventional thermometer.
HI 91541 provides accurate and consistent
readings not only for lower values but also
for temperatures as high as 300°C (570°F).
To prolong battery life, it shuts itself off au-
tomatically after half hour of non-use.
HI 91541 and HI 9061 have been specifically
designed by Hanna Instruments for use in
the food industry and are available in two
versions:
HI 9061C to measure in degrees Celsius;
HI 9061F to measure in degrees Fahrenheit.
HI 91541C to measure in degrees Celsius;
HI 91541F to measure in degrees Fahren-
heit.
Each HI9061C and HI9061F comes supplied

4
complete with 4 batteries (1.5V, AA size).
Upon request these meters can be supplied
with a Factory Calibration Certificate against
NIST standard. Several types of HI 765 tem-
perature probes are available to meet all
your requirements (see page 15). A series
of HI765 calibration test plugs are also
available to check the meter's accuracy (see
page 13).
Each HI91541C or HI91541F comes sup-
plied complete with 4 batteries (1.5V, AA
size). Several types of HI 764 temperature
probes are available to meet all your re-
quirements (see page 16). A series of HI764
calibration test plugs are also available to
check the meter's accuracy (see page 13).
HI9060 can measure in Centigrade and in
Fahrenheit.
Other features of HI 9060 include: display
and clearing of the maximum / minimum tem-
perature measured reading hold. These func-
tions are easily accessible through the wa-
terproof rubber keypad. Self-explanatory sym-
bols are used to remind the user of the
operating mode or condition.
HI 9060 comes supplied complete with 4 bat-
teries (1.5V AA size) and a HI765BL ther-
mistor probe with 1 meter (3.3') cable. Sev-
eral types of HI 765 temperature probes
are available to meet all your requirements
(see page 15). A series of HI765 calibration
test plugs are also available to check the
meter's accuracy (see page 13).

OPERATIONAL GUIDE
INITIAL PREPARATION
Each meter is supplied com-
plete with batteries.
Remove the back cover, un-
wrap the batteries and install
them while paying attention to
their polarity.
To switch on, press the ON/OFF key on the
front of the unit.
If the meter does not come on, make sure
that the batteries securely sit in their place.
Each time the thermometer is switched on, it
will carry a self-test to
ensure that no segment
is missing. The LCD
shows a full set of fig-
ures during the self-test.
After the test the ther-
mometer will resume its operational mode.
If a temperature probe is plugged in, the unit
displays the probe temperature.
If a probe is not plugged in, or the cable is
defective, the display will show "Er" (for
HI 9060 and HI 9061) or "--------
--------
----" (for HI 91541).
To switch your thermometer off, press the
ON/OFF key again.

HI / LO MEMORIES (for HI 9060 only)
The 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.
Enquiries of the highest or lowest measured
temperature may be made by pressing the
respective HI or LO keys.
The appropriate display indicator will appear
together with the value retrieved from memory.
Release the key to resume normal operation.
By pressing the CLEAR key, the present
measurement reading becomes the highest
and lowest temperature in memory, i.e. both
HI / LO are the same temperature reading.
The "HI/LO" display indicator will blink twice
to notify user that clearing process is in
progress.

HOLD MODE (for HI 9060 only)
The reading hold function is activated by the
HOLD key. The measured temperature is
frozen on the display when this function key
is pressed.
A blinking "M" on the display indicates the
operating mode.
Press the same key again
to resume normal opera-
tion.
MEASURING SCALE (°C/°F) (for HI9060
only)
When the meter is
turned on it automatically
defaults to the °C scale.
Measurements can be performed in either
the Centigrade or Fahrenheit scale. To change
the scale, press the °C/°F key once.
