2. Operation
2.1 Calibration
2.1.1 Buffer solution groups
The instrument can be calibrated for 1, 2 or 3 points. During calibration, the meter
automatically recognizes the pH of the standard buffer solution. The automatic
temperature compensation procedure is solidified in the meter (see appendix).
The instrument has 8 sets of buffer solution (see appendix). The settings for the
buffer solution group refer to 2.4.1.
2.1.2 One point calibration
2.1.2.1 Calibration
Place the electrode in the buffer and press the "CAL" button to start the
calibration. The calibration icon will be displayed. After the signal is stabilized,
the instrument will automatically end according to the preselected end point or
press the "OK" button.
2.1.2.2 Save the calibration results
After measuring the value is stable, press the "OK" button, the instrument shows
the zero and slope, automatically returned to the measurement screen.
Note:
When performing a little calibration, only zero is adjusted. If the electrode is
over-calibrated before, its slope will be saved, otherwise the theoretical slope
(-59.16mV/pH) is taken. Press the "CAL" button, the meter will display the slope
