10.3.3 Drift control (AutoRead)
The drift control function (AutoRead) checks the stability of
the measured value. The stability has a considerable effect
on the reproducibility of the measured value.
Note
In order to accept the current measured value without
waiting for the end of the AutoRead function, simply press
g
. You can only change to another measured variable
after completion of AutoRead.
1 Select the required measuring mode with
46
.
2 Immerse the conductivity measuring cell in the test
sample.
3 Activate the AutoRead function with
a
.
The measured value is frozen (hold function).
4 Start the measurement with AutoRead by pressing
g
.
The
h
AR display indicator flashes. When a stable
signal is reached, an acoustic signal is heard and
h
stops flashing.
5 If necessary, start the next measurement with
AutoRead by pressing
