USING THE METER

3.1

Electrodes

This meter allows you to use two types of pH electrodes: the
conventional glass pH electrode and the field effect transistor (FET)
electrode. If both types of electrodes are connected, the meter will
read the FET electrode.
1. Carefully remove the protective
cover from the end of the electrode.
Before first using your glass pH
electrode, soak it 2-4 hours in an
electrode storage solution, pH 4
buffer, or KCI solution.
2. Remove the shorting cap on BNC connector. Connect the
combination pH electrode in to the BNC input connector.
If a combination electrode isn't used, connect the indicating pH
electrode into the BNC input connector. Plug the reference
electrode into the reference pin jack. Also, install the ATC probe
into the ATC jack.
Note: be sure to connect all probes to the appropriate channel
connectors (for example: Input 1, Ref 1 and ATC1).
Option: Connect the optional FET electrode by plugging it into
the FET jack on the back meter panel. Allow the FET electrode to
warm up five minutes before use.
