Connecting the

plug-in power sup-

ply (option)

You can either operate the measuring instrument with batteries or with the

plug-in power supply. The plug-in power supply supplies the measuring in-

strument with low voltage (12 V DC). This saves the batteries.

Caution

The line voltage at the operating site must lie within the input voltage range

of the original plug-in power supply (see

section 1.4 T

ECHNICAL DATA).

Caution

Use original plug-in power supplies only (see

section 1.4 T

ECHNICAL DATA).

Note

You can also measure without the plug-in power supply.

1 Plug the jack (1) into the socket (2) of the measuring instru-

ment.

2 Connect the original SI Analytics plug-in power supply (3) to an

easily accessible mains socket.
