5.3. USING HANNA DIGITAL ELECTRODES
The
HI83303
can be used to perform direct pH measurements by connecting a HANNA
®
digital
pH electrode with a 3.5 mm TRRS connector. To begin taking probe measurements, connect the
electrode to the 3.5 mm port marked with “EXT PROBE” located at the rear of the meter. If the
meter is in “Photometer Mode”, set the meter to “Probe Mode” by pressing the
MODE
key.
5.4. MODE SELECTION
The
HI83303
has two operational modes: Photometer Mode and Probe Mode.
Photometer Mode enables on‑demand measurement of a cuvette using the integrated optical
system. Photometric‑related functions, such as Method selection, Zero, Read, and Timers are
available in this mode.
Probe Mode enables continuous measurement using a Hanna Digital Electrode connected to the
3.5 mm port. Probe‑related functions, such as calibration and GLP, are available in this mode.
To switch between Photometer Mode and Probe Mode, use the
button.
Note: The active mode cannot be switched while in menus, such as Setup, Recall, Method, etc.
