a. Starting Calibration
For Alkalinity and Hardness, calibration is begun by pressing
when the titration is complete and a value displays.
For Conductivity, TDS or pH, calibration is begun by pressing
while measuring Conductivity, TDS or pH. Measuring continues, but
the “cal” icon is on, indicating calibration is now changeable. The
reading is changed with the and keys to match the
known value.
The calibration for each of the 4 solution types may be performed in
either conductivity or TDS mode.
Once in CAL mode, the key becomes an “ACCEPT” key for the
new calibration.
For pH, at each point, pressing accepts the new calibration
value and steps you to the next adjustment.
To bypass a calibration, simply press to accept the present
value as-is.
b. Leaving Calibration
Pressing accepts calibration and exits CAL mode if there are no
more steps. Calibration is complete when the “cal” icon goes out.
Pressing any measurement key during calibration cancels changes
not yet accepted and exits calibration mode. Leaving pH after the 2nd
buffer results in the same gain being entered in place of the 3rd buffer.
2. Calibration Limits
There are calibration limits for all functions for which calibration is
required. For Alkalinity and Hardness, the 9P will not allow you to
