P4.2: Selecting number of pH calibration points Program P4.2 lets you select the number of calibration points that appear in pH calibration mode: 2, 3, 4, or 5. This lets the meter scroll through the calibration points more quickly if you regularly calibrate at less than 5 points.
*The READY indicator appears and the reading holds until the measured value exceeds the tolerance
(± 0.02 pH; ± 0.8 mV <400; ±1.2 mV >400). Then, the READY annunciator turns off.
