10/2011

4.1.4 Socket field

4.2

Switching on the meter

1 pH electrode
2 Reference electrode
3 Temperature sensor
4 Mini USB-B interface
5 Power pack
6 Service interface

CAUTION

Only connect sensors to the meter that cannot return any volt-
ages or currents that are not allowed (> SELV and > current
circuit with current limiting).

Almost all customary sensors meet these requirements.

Press the

<On/Off>

key.

The meter performs a self-test.

The display shows the manufacturer's logo while the self-test is being
performed.

The measured value display appears.
