Multi 3400i Operation

4.3.4 AutoRead AR (Drift control)

The AutoRead function (drift control) checks the stability of the mea-

surement signal. The stability has a considerable impact on the repro-

ducibility of the measured values.

Criteria With identical measurement conditions, the following applies:

1 Call up the measuring mode with <M> and/or <▲> <▼> .

2 Activate the AutoRead function with <AR>. The current mea-

sured value is frozen (hold function).

3 Start AutoRead with <RUN/ENTER>.

AR flashes until a stable measured value is reached. This mea-

sured value is transmitted to the interface.

4 If necessary, start the next AutoRead measurement with

<RUN/ENTER>.

5 To terminate the AutoRead function: Press the <AR> key.
