5 Description

In the basic version of the QMS 422 and on the QMI 422 the front panel contains
only a power switch and the corresponding LED.

The CS 422 operator console is available as an option. It can easily be retrofitted
and is highly recommended for learning purposes, e.g. for software development.
Even if you do not have a CS 422 you should carefully read the following
information. This will enhance your understanding also in computer mode.

With the

keys you can optimize the display contrast.

After a function has been selected, e.g. (

mass

key) the function (SETUP MASS),

its parameters (here

MODE

,

SPEED

...

RESOL

) and parameter values and the

measured value of the selected channel are displayed.

Parameter menus depend on the parameter state; in the picture below a
changeover to

MODE:SAMPLE

has been made

In computer mode the parameters are displayed for approx. 30 s when a key is
pressed. Input operations are disabled. Subsequently the measured value display
reappears automatically.
