Shows the current software issue level.
Set the required control temperature within the range 20 to
45C in 0.1C increments. This temperature should be set to
5C above the maximum ambient temperature expected.
Set the required display units for phosphate concentration
(ppm, mg/l or mg/kg).
Set the display type as P (Phosphorus) or
(Orthophosphate).
Enter setup security code (up to four digits) if required.
Set the current (real) date and time respectively.
Set frequency as either OFF, MANUAL, 24hr, 12hr, 6hr, 3hr or
1hr. If MANUAL is selected the color compensation can only
be initiated from Programming Page 2.3.
Value of color compensation applied. If 'Default programming
parameters' (Programming Page 2.1) is set to YES, 'Color
comp frequency' is set to 0.
Set the date and time respectively.
Set the current output to any range between the following
maximum and minimum limits:
3–
PO

0 to 3
and
0 to 60
If set to YES the Current Outputs are held during calibration.
Set to one of the following ranges: 0 to 10, 0 to 20 or 4 to
20mA.
If required, the instrument can automatically transmit a
percentage of the full scale test signal: 0, 25, 50, 75, 100% of
the current output selected.
Select YES or NO as required.
Set the required setpoint values within the instrument range.
Select the alarm action required - HIGH or LOW.
If fail-safe action is required select YES.
Relay actuation and alarm l.e.d. indication can be delayed in
the event of the alarm condition. If the alarm condition clears
within the programmed delay time, the alarm function is not
activated and the delay time is reset. Set the required delay
time in the range 0 to 99 minutes in 1 minute increments.
A differential set point can be set as a percentage of the set
point value. The differential setting operates on the set point.
Example – a 5% differential setting operates 2.5% above and
below the setpoint.
Set the differential required between 0 and 5% in 1%
increments.
Enter the value of the previously entered security code.
