Note: Always take notice of the following precautions when using the adapter:
Users should be able to insert the adapter with light to moderate pressure. Never use excessive
force to insert the adapter.
If the adapter is not reaching the bottom, if there is resistance, re-check that the positioning
marks are aligned on the adapter and arm holder’s head.
8.2. USING THE ELECTRODE HOLDER
Place electrodes in the holder for support and easy movement in and out of beakers and containers.
The electrode holder easily positions electrodes during calibration, sample measurement, and storage
with protective cap on.
8.3. CONNECTING ELECTRODES & KEYBOARD
Connecting the electrodes
Any analog pH or ORP electrode with BNC connector (non-amplified or non-digital) can be used with
the meter. pH or ORP half-cell sensors and separate reference electrode with suitable jack connectors
can also be used.
Hanna Instruments pH electrodes with integral temperature elements are also supported.
The HI1131B glass-bodied combination pH electrode is connected through a BNC connector, which
makes attaching and removing the probe an easy process.
When connected, the probe is automatically detected.
With the meter off:
• Connect the probe to the BNC connection port, on the top right of the meter.
• Align the key and twist the plug into the socket.
• Place the probe into the holder and secure the cable in the cable holder clip.
• Power the unit.
The temperature probe, HI7662-TW, is connected to the benchtop unit through an RCA connector.
With the meter off:
• Plug the connector into the socket.
