pH and ORP Calibration
>SYSTEM 1 pH CALIBRATION<
1 POINT CAL
2 POINT CAL
1 POINT –
With a clean probe on-line seeing the
system’s water enter the known (tested from a
calibrated hand held tester) value.
2 POINT –
Enter a known Low value with a
clean probe in a buffer solution. Then enter a
known High value with the clean probe in a
buffer.
☼
Notes: 1.
Probes must be rinsed between buffers when doing a 2 Point calibration and given at
least 30 seconds in solution to adjust to the buffer.
2.
There must be at least 2 full pH points between buffer solutions. Using a buffer of 4
and 10 is the best procedure. ORP buffers should be at least 200 points apart.
4. Timers
A unit may have up to 5 selectable timers for each system on a controller. All timers are associated
with their system, so for a % of post bleed timer looks at the bleed of that system.
