Each meter is supplied with batteries. Remove the battery cap, un-
wrap the supplied batteries and install them while paying attention to
their polarity (see also the "Battery replacement" section for more
details).
TAKING MEASUREMENTS
Connect a suitable temperature probe to the meter (see pages 12-14 for
a complete list of Hanna probes).
Note: HI 935007 has a fixed probe.
To switch the meter ON, press the ON/OFF
button on the front of the meter. If it does not
turn on, make sure that the batteries are
properly installed in their place.
At start-up the thermometer displays all LCD
segments for a few seconds, followed by the
percentage indication of the remaining battery
life; then it enters Cal Check mode and then
enters measurement mode.
Note: The full display can be frozen by
keeping the ON/OFF button pressed.
If a temperature probe is plugged in, the meter displays the measured
temperature.
If no temperature probe is plugged in or the reading is over-range, the
display shows blinking dashes. If the reading is slightly beyond the
measuring range, the meter flashes the closest full-scale value.
To switch the meter OFF, press the ON/OFF key.
AUTO-OFF FEATURE
To save battery life, each model is provided with an auto-off feature,
which switches the instrument off after a certain period of non use.
The auto-off delay time is 8 minutes.

CALIBRATION CHECK
All the models are provided with auto-
matic Cal-Check feature at start-up, which
allows the user to check the instrument
calibration status.
If the meter is calibrated, the display
will stabilize and show “0.0 °C” (±0.3
°C) in a few seconds.
Contact your dealer or your nearest Hanna
Service Center for recalibration, if necessary.
HOLD FEATURE (HI 93501S, HI 93503)
The hold function is activated by pressing
the HOLD key.
The measured temperature and the stabil-
ity bargraph is held on the display until
HOLD is pressed again.
The “HOLD MODE” tag blinks on the dis-
play while in Hold mode.
STABILITY INDICATOR (HI 93501S, HI 93503)
A stability indicator with seven levels of
bargraph is provided on the LCD. Until
the reading become stable the “WAIT”
tag is on.
When the reading is inside ±0.1 °C win-
dow the “STABLE” tag become on stability
bargraph is full.
