age indication of the remaining
battery life for a few seconds, and
then enters measurement mode.
If a temperature probe is plugged in, the meter displays
the measured temperature either in °C (HI 8757) or °F (HI
8758), automatically switching to the resolution suitable to
the temperature range; i.e. 0.1° up to 199.9°C (399.9°F),
or 1° above.
If no probe is plugged in, or if
reading is over-range, the dis-
play shows flashing dashes.
If a measurement is slightly over the range of the meter
specifications, the display flashes the closest full-scale value.

FACTORY RECALIBRATION
All Hanna thermometers have been accurately pre-cali-
brated at the factory. It is generally recommended to have
all thermometers recalibrated at least once a year.
For an accurate annual recalibration, contact your dealer or
the nearest Hanna Service Center.

BATTERY REPLACEMENT
The instrument is powered by a 9 V battery and is
provided with Battery Error Prevention System (BEPS),
which turns the unit off when a low battery signal is
detected.
When the battery level is less than
10%, a warning symbol blinks
on the display to indicate a low
battery condition.
It is recommended to replace the battery as soon as the low
battery condition is detected.

Remove the cover on the meter's back by applying pressure
in the indicated direction. Unplug the rundown battery
and replace it with a new one.
Battery replacement must only take place in a nonhazard-
ous area using a 9V alkaline battery.
