Zero Value
pH (or mV or Deg.C or Deg.F or A-B) and Adjust are shown alternately on the
center display line. Use the and keys to adjust the displayed reading to the
required zero value:
Note. The zero value setting plus the minimum differential determines the
minimum and maximum values for the span setting, e.g. to set a span value
of –1100mV, first set the zero value to –1200mV.
pH –2.00 to 14.00 pH (minimum differential, 2.00pH)
ORP/Redox –1200 to 1100 mV (minimum differential, 100mV)
Temperature Deg. C –10.0 to 140.0 (minimum differential, 10°C)
Deg. F 14.0 to 284.0 (minimum differential, 18°F)
A-B – –2.00 to 12.00 pH (minimum differential, 2.00pH)
Note. A-B is applicable only to dual input analyzers.
Default Output
Select the system reaction to failure:
Hold – Hold the analog output at the value prior to the failure.
On – Stop on failure. This drives the analog output to the level set in the
Default Val frame below.
Off – Ignore failure and continue operation.
Default Value
The level to which the analog output is driven if a failure occurs.
Set the value between 0.00 and 22.00mA
Output 2 configuration (and Outputs 3 and 4 if option board fitted
and analog features enabled – see Section 6.1.3) is identical to
Output 1 configuration.
Option board fitted and analog features enabled (Section 6.1.3) –
see Section 5.1.7.
Option board fitted and Serial Communications feature enabled
(Section 7.3) – see Supplementary Manual PROFIBUS Datalink
Description (IM/PROBUS).
Single input analyzer and option board not fitted – see PID Control
Supplement (IM/AX4PID).
Dual input analyzer and option board not fitted – see Section 5.8.
