1. Connect the pH sensor to the meter.
The pH measuring window is displayed.
2. Keep the buffer solutions ready.
3. Start the calibration with
<CAL>
.
The calibration display for the first buffer appears (voltage display).
4. Thoroughly rinse the sensor with deionized water.
5. Immerse the sensor in the first buffer solution.
6. Start the measurement with
<ENTER>
.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter
flashes.
7. Wait for the end of the measurement with stability control (beep,
[HOLD][AR] status indicator) or take over the calibrated value with
<ENTER>
.
The calibration display for the next buffer appears (voltage display).
8. If necessary, finish the calibration procedure as a single-point calibra-
tion 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 IDS-
pH sensor.
