EASY TO USE PRODUCTS

Configure your recorder in few steps :

Select the operating mode of

the recorder.

Access to the parameters of each

channel,

access to the functions between

channels.

Or let the autoset do the job !

As an oscilloscope, the recorder

displays the signal on the screen with

numeric values.

Setup triggering parameters of the

acquisition on paper, in internal

memory or on file according to the

current operating MODE.

Select the channels used for the

data acquisition.

Save recorder setup

RECORD !

You can save your data on 8 GB hard disk or on

32 Mword memory for fastest acquisition.
