User Guide

When the batteries are inserted and no power adapter is connected,

the meter can recognize two different batteries charge levels.

1. Weak batteries - "bAt" indication

is displayed on the secondary LCD

alternating the temperature read-

ing. The meter can still work for

about 10 hours.

2. Dead batteries - meter shuts off

and stops working to avoid errone-

ous readings.

Battery replacement must only take place

in a non hazardous area using 1.5V

alkaline AA type batteries.

In order to replace rundown batteries,

simply remove the two screws of the rear

cover and replace the four 1.5V AA

batteries with new ones, while paying

attention to the correct polarity.

A 12 VDC power adapter can also be used to power the unit (see

accessories).

Note: The instrument uses the following configuration.

It is recommended to purchase the Hanna voltage adapters that use

the proper polarity configuration.

However, HI 504920 can be used also with other adapters. In this

case, check the correct polarity of the adapter before connecting it to

the meter.
