Continuing with two-
point calibration
7.
When measuring without temperature sensor:
Enter the temperature of the buffer 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 setting of the nominal buffer value
appears.
10.
Set the nominal buffer value for the measured temperature with
<><>.
11.
Accept the set calibration value with <ENTER>.
The calibration display for the next buffer appears (voltage display).
12.
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.
