3.0 Optional Mid-Run Standardization Check
3.1
Sequence of Optional Mid-Run Standardization Check
1. Pause the pH control loop on the
BPC control system.
Remove the red
safety zip tie if one was installed.
2. Retract the glass pH sensor into
the buffer storage chamber.
3. The glass pH sensor should
now read within 0.05 pH units
of the calibration tag value.
4. Decision Point:
If a 1-point
standardization is necessary,
use the buffer storage
chamber pH or a grab sample.
5. The calibration is
complete. Reinsert
the glass pH sensor.
6. If the change in pH is more
than 0.2 pH units, reset integral
on the proportional-integral-
derivative (PID) parameter.
