User Guide

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 en-

abled.

2. Weakening batteries - "LOBAT" symbol blinks on LCD. The back-

light 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 lower LCD. Back-

light and printer are disabled and 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 replac-

ing the batteries or connecting the

external power adapter, the meter will

show "batt" on LCD.

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, sim-

ply remove the two screws on the rear cover

of the instrument and replace the four 1.5V

AA batteries with new ones, paying atten-

tion to the correct polarity.

A 12VDC power adapter can also be used to

power the unit (see the accessories para-

graph).

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, the meters can be used with other adapters. In this case,

remember to check the correct polarity of your adapter before connect-

ing it to the meter.
