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)

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 7.3) is identical to Output 1 configuration.
Option board fitted and analog features enabled (Section 7.3) – see Section 5.7.
Option board fitted and Serial Communications feature enabled (Section 7.3) –
see Supplementary Manual PROFIBUS Datalink Description (IM/PROBUS).
