Use one to five buffer solutions of the selected buffer set in any order.
Below, calibration with Technical buffers (TEC) is described. When other buffer
sets are used, other nominal buffer values are displayed. Apart from that, the
procedure is identical.
If single-point calibration was set in the menu, the calibration proce-
dure is automatically finished with the measurement of buffer solu-
tion 1 and the calibration record is displayed.
1. Connect the pH sensor to the meter.
The pH measuring window is displayed.
2. Keep the buffer solutions ready.
When measuring without temperature sensor:
Temper the buffer solutions or measure the current temperature.
3. Start the calibration with
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. For measurements without temperature sensor
(e.g. when using an IDS adapter
Enter the temperature of the buffer with
7. Start the measurement with
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter
flashes.
