4. Standardize the meter using
up to three buffers by immers­ing the electrode in a buffer,
then pressing Standardize to
enter each buffer.

Installing and Maintaining Electrodes

This meter allows you to use two types of pH electrodes: the
pH glass electrode and the field effect transistor (FET) pH elec­trode.If both types of electrodes are installed,the meter will
read the FET electrode.

NOTE: If both electrodes are connect­ed to the meter, do not put them in a solution together
because you will get inaccurate measurements.

1.Remove the protective end

cover from electrode.

3.Remove the shorting cap on the BNC connector.Install the com­bination glass pH electrode by plugging it into the input connec­tion (twist-lock) and the ATC connector into the ATC jack.

2.Before first use of your glass pH
electrode,or whenever the
electrode is dry,soak over-night
in a filling or KCI solution.

4.

Option:

Install the optional FET electrode by plugging it into the FET
jack on the back of the meter panel.Allow the FET electrode to
warm up for one minute prior to use.

5.

Option:

Install ORP or Ion Selective Electrode pairs by removing the
BNC shorting cap and plugging the BNC connector (twist-lock)
into the BNC jack.If a combination electrode is not used, plug the
reference electrode into the ref pin.
