Continuing with two-
point calibration
5. Thoroughly rinse the electrode with deionized water.
6. Immerse the electrode in the first buffer solution.
7. When measuring without temperature sensor:
Measure the temperature of the buffer and enter it with <><>.
8. Start the measurement with <ENTER>.
The measured value is checked for stability (stability control). The [AR]
status indicator is displayed. A progress bar is displayed and the display
of the measured parameter flashes.
9. Wait for the end of the measurement with stability control or accept the
calibration value with <ENTER>.
The calibration display for the next buffer appears (voltage display).
10. If necessary, finish the calibration procedure as a single-point calibration
with <M>.
The calibration record is displayed.
For single-point calibration, the instrument uses the Nernst slope
(-59.2 mV/pH at 25 °C) and determines the zero point of the elec-
trode.
