1.1 Keypad
In this operating manual, keys are indicated by brackets <..> .
The key symbol (e.g. <ENTER>) generally indicates a short keystroke
(under 2 sec) in this operating manual. A long keystroke (approx.
2 sec) is indicated by the underscore behind the key symbol (e.g.
<ENTER_>).

Caution
Only connect D.O. sensors to the meter that cannot return any
voltages or currents that are not allowed (> SELV and > current
circuit with current limiting).
Almost all customary D.O. sensors fulfill these conditions.
