6.7. BATTERY MANAGEMENT
The meter will perform an auto-diagnostic test when it is powered on. During this test,
the Hanna Instruments

logo will appear on the LCD. If the auto-diagnostic test was
successful, the meter is ready for use. The battery icon on the LCD will indicate the
battery status:
• battery full
• battery below 10%, replace the batteries soon
• battery is low, replace the batteries with new ones
To conserve battery, the meter will turn off automatically after 15 minutes of
inactivity. If a zero reading has been done but not a read, auto-off time is increased
to 30 minutes.
