OPERATIONAL GUIDE

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.
