Connection of pH or ORP electrode
<When Iwaki SensorRex is used>
Set the respective wiring terminals of the pH electrode as shown in the
figure. Check the terminals with the respective tags attached for a
correct connection. The electrode which has a model number ending
with "TV" has 5 wires on it. The electrode which has a model number
ending with "V" has 2 wires on it. In the case of the TV type, remove
the resistor installed at the T-T terminals before connecting the wires.
An OPR electrode has two wires only, which are not to be connected
to the terminals T and E. No resistor is attached, either.
