VSTAR-LR Versa Star pH/LogR Module
8 pin MiniDIN
BNC
Pin Tip
1. Remove the shorting cap protecting the BNC connector on the module.
2. Connect a pH electrode or ORP electrode to the BNC connector on the module. LogR
technology allows the temperature to be measured using the glass bulb of a pH electrode.
3. Connect an ATC temperature probe to the 8 pin MiniDIN connector on the module.
4. Connect a reference half-cell electrode to the pin tip connector on the module (for use
when a half-cell sensing electrode with BNC connector is used).
5. Prepare the electrodes for use as instructed in the electrode user manuals.
