Continuing with two-
point calibration
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 pH value of the buffer solution is displayed.
8.
Set the nominal buffer value for the measured temperature with
<

.
9.
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 IDS-
pH sensor.
