Hanna Instruments hi 98140 User Manual

When the batteries are inserted and no power adapter is connected,
the meter can recognize different batteries charge levels.
1. Fully charged batteries - The backlight can be enabled.
2. Weakening batteries - The backlight is automatically disabled

and it is not possible to enable it until new batteries are inserted
or an external power adapter is connected. The "Batt" indication
appears when trying to enable backlight.

3. Weak batteries - "Bat" indication is displayed on lower LCD

alternating the temperature reading. Backlight is disabled and
meter can work for about 10 hours.

4. Dead batteries - LCD shuts off. The instrument stops working to

avoid erroneous readings.

Battery replacement must only take place
in a non hazardous area using 1.5V
alkaline AA type batteries.
In order to replace run down batteries,
simply remove the two screws on the rear
cover of the instrument and replace the
four 1.5V AA batteries with new ones,
paying attention to the correct polarity.
A 12VDC power adapter can also be used
to power the unit (see accessories).

Note: The instrument uses the following configuration.

It is recommendable to purchase the Hanna HI710005 and HI710006
voltage adapters that use the proper polarity configuration.
However, HI 98140 and HI 98150 can be used with other adapters.
In this case, remember to check the correct polarity of your adapter
before connecting it to the meter.
