SETUP - Adjustments

4.1

System setup

The System setup is selected using either the softkey »Setup«

in the main menu or via the function button SETUP.

OK The displayed parameter setup resp.

adjustments are accepted and the previous

menu appears.
EDIT Switch to the functional selection/

entry menu for editing the para-meter

values.

4.1.1 Channels

Measurement channel 1

Channel 1 is active

Measurement channel 1+2

Channels 1 and 2 are active

Note:

When measurement channel 1 is selected, only the channel

that is designated as channel 1 will be active !

4.1.2 Setup 1=2

Identical configuration for channel 1+2

Yes*

Identical configuration for channel 1+2

∗

With the selection »Yes« the configuration of channel 2 is

overwritten by the configuration of channel 1. This provides

the user the option to quickly copy the setup from channel

to channel 2.
