User Guide

The meter automatically checks for entered time/date accuracy as follows:

0≤hh≤23; 0≤mm≤59; 01≤dd≤28/29/30/31; 1≤MM≤12; 1998≤YYYY≤2097.

To change the password, the correct code must be entered first. If the password

has been forgotten, the password protected features are no longer accessible;

in this case contact your nearest Hanna Service Center.

Some of the setup parameters are explained below.

Code 00 - Setting the identification (ID) code

When using several identical meters it may be useful to uniquely

identify them by assigning an ID code to each meter.

• Select code 00.

• Enter a 4-digit value using the arrow keys.

• Press ALT and CFM to confirm the value.

Code 20 - Auto-off

The auto-off timeout is fixed at 5 minutes.

• Select code 20 to enable/disable this feature.

Code 22 - Battery level test

• Select code 22.

• If the meter is connected to an external power adapter, the LCD

will display "LINE" otherwise it will display "bAtt" on the upper

display, and the remaining percentage

of battery charge (100% means fully

charged battery and 0% corresponds to

the minimum battery voltage that allows

the meter to operate).

Note: the battery level test is also performed any time the meter is

turned on.
