3. Press to verify pH
calibration. If the display
shows 7.00, skip the pH
Zero Calibration and
proceed to section b.
pH Gain Calibration.
4. Press to enter calibration mode. The “CAL”, “BUFFER”
and “7” annunciators will appear (see Figure 5). Displayed
value will be the uncalibrated sensor.
NOTES: If a wrong buffer is added (outside of 6-8 pH),“7” and
“BUFFER” will flash, and the P
ool
P
ro
will not adjust.
The uncalibrated pH value displayed in step 4 will assist in determining
the accuracy of the pH sensor. If the pH reading is above 8 with pH 7
buffer solution, the sensor well needs additional rinsing or the pH sensor
is defective and needs to be replaced.
5. Press or until the display reads 7.00.
NOTE: Attempted calibration of >1 pH point from factory calibration will
cause “FAC” to appear. This indicates the need for sensor replacement
(ref. Troubleshooting pg. 34) or fresh buffer solution. The “FAC” internal
electronic calibration is not intended to replace calibration with pH
buffers. It assumes an ideal pH sensor. Each “FAC” indicates a factory
setting for that calibration step (i.e., 7, acid, base).
You may press to accept the preset factory value, or you may
reduce your variation from factory setting by pressing or .
6. Press to accept the new value. The pH Zero Calibration
is now complete. You may continue with pH Gain Calibration or
exit by pressing any measurement key.
