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 and printer can be
enabled.
2.
Weakening batteries
- "LOBAT" symbol blinks on LCD. The
backlight and printer are automatically disabled and it is not
possible to enable them until new batteries are inserted or an
external power adapter is connected.
3.
Weak batteries
- "LOBAT" symbol stays still on the lower LCD.
Backlight and printer are disabled and the meter can work for
about 20 hours. If in Timed logging mode with the power down
function enabled, this time can be longer.
4.
Dead batteries
- LCD shuts off. The instrument stops working to
avoid erroneous readings.
Note
It is not possible to activate backlight and printer when the
instrument is in a low battery condition. If the user attempts to
enable these functions without replacing
the batteries or connecting the external
power adapter, the meter will show
"bAtt" on LCD.
Battery replacement must take place only 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 the accessories sec-
tion).
Note:
The instrument uses the following configuration.
It is recommendable to purchase the Hanna
HI 710005
and
HI 710006
voltage adapters that use the proper polarity configuration.
However, the meters can be used with other adapters. In this case,
remember to check the correct polarity of your adapter before connecting
it to the meter.
