Continuing with two-
point calibration
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
)
:
Measure the temperature of the buffer manually and enter it with
< S S S S >< T T T T > .
7. Start the measurement with <ENTER> .
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter
flashes.
8. 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).
9. 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.
