Zero Value
%Sat
(or
ppm
or
mg/l
) and
Adjust
are shown alternately on the center display line. Use the
and
keys to adjust the displayed reading to the required zero value:
%Sat
– 0.0 to 230.0 %Sat (minimum differential, 20.00 %Sat)
ppm
– 0.00 to 23.00 ppm (minimum differential, 2.00 ppm)
mg/l
– 0.00 to 23.00 mg/l (minimum differential, 2.00 mg/l)
Note.
The zero value setting plus the minimum differential determines the minimum and
maximum values for the span setting, e.g. to set
Span Value
to 2.0 ppm, first set
Zero Value
to 0.00 ppm.
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
