Note.
1. Where pH systems are used with a Solution Earth (ground rod) and those including diagnostics, ensure that
the relevant sensor(s) is set to
2. If the sensor is fitted with a 2-wire Pt100, Pt1000 or Balco 3K temperature compensator, link terminals B9 and B10 (and B1
and B2 if dual input analyzer).
The redox (ORP) version of the 7650 series does not incorporate a temperature sensor. The Temperature sensor must be
disabled in the Configuration page - see section 5.3, page 30.
