6. GENERAL OPERATIONS
6.1. POWER CONNECTION & BATTERY MANAGEMENT
The meter can be powered from an AC / DC adapter (included) or from the built-in rechargeable
battery.
The meter will perform an auto-diagnostic test when it is first powered on. During this test, the Hanna
Instruments logo will appear on the LCD. After 5 seconds, if the test was successful, the last method
used will appear on the display.
The battery icon on the LCD will indicate the battery status:
• battery is charging from external adapter • battery fully charged (meter connected to AC / DC adapter)
• battery capacity (no external adapter)
• battery near 0% (no external adapter)
• battery exhausted (no external adapter)
To conserve battery, the meter will turn off automatically after 15 minutes of inactivity (30 minutes
after a Zero measurement). If a photometer measurement is on the screen, an auto-log is created
before shutdown.
6.2. MODE SELECTION
The
HI83326
has two operational modes: Photometer and Probe.
Photometer mode enables on-demand measurement of a cuvette using the integrated optical system.
Probe mode enables continuous measurement using a Hanna digital electrode connected to the
3.5 mm port.
To switch between Photometer mode and Probe mode, use the
MODE
key.
Note:
The active mode cannot be switched while in Setup, Recall or Method menus.
