AutoRead

(drift control)

The AutoRead function (drift control) checks the stability of the measurement 
signal. The stability has a considerable impact on the reproducibility of the 
measured values.

For identical measurement conditions, the following criteria apply:

Note

The current AutoRead measurement can be terminated at any time (accept-
ing the current value) by pressing <RUN/ENTER>.

Reproducibility

Response time

Better than 0.02

> 30 seconds

1

Call up the pH measuring mode with 

<M>

 and

.

2

Activate the AutoRead function with 

<AR>

.

The current measured value is frozen (hold function).

3

Start AutoRead with 

<RUN/ENTER>

.

AR

 flashes until a stable measured value is reached.

This measured value is transmitted to the interface.

4

If necessary, start the next AutoRead measurement with 

<RUN/EN-

TER>

.

5

To terminate the AutoRead function: Press the 

<AR>

 key.
