2.2 Installing the stand-alone electrode holder
Install the electrode arm on the base,
After adjusting the tension knob to some extent, you can move the upper arm up and down.
When the pH electrode is installed on the arm, the storage bottle of pH electrode fits into the
base hole.
2.3 Installing the power adapter
Insert the right adapter clip into the power adapter slot. The Ohaus balance power supply is also
12V which could also be used for the pH meter.

2.4 Connect the pH electrodes
There are 3 sockets for electrode. “pH”socket (BNC); “TEMP.”Socket (Cinch) and “REF”Socket
(2mm banana).
For ST310 electrode connect to the BNC and Cinch socket. For 2-in-1 pH electrode (e.g. ST210)
you only need to connect the BNC.
REF socket is for separate reference electrode. (e.g.STREF1)
2.5 Meter stand for adjusting view angle
One unique design of the STARTER 3100 is the meter stand, which can be used to adjust the view
angle of the display in case of working on high table.
2.6 Attached quick guide
Another unique design of the STARTER 3100 is the attached quick guide, the quick guide is
attached into the bottom housing of the meter.
