Operation 15

*)

 The zero adjust function respectively the amplifier adjustment is activated by pressing  "Activate". 

In order to find the optimal adjustment value, the calculation of averages is activated for 200 msec.

The input signal should not be changed at this time. 

At the amplifier adjustment 3 fault conditions are possible:
"GainH":   calculated amplification is too high

 

"GainL":   calculated amplification is too low

 

"Zero":   actual calibration weight is too low

Following page appears:

By pressing "Save" the changed parameter values are transferred to the long-term memory. In contrast, 

the page is exited by pressing "Esc" without saving the entries.

To assure that the modified values even after a restart are still present, the field labeled "y" must be pressed 

in the amplifier overview page.
