In general
When configuring the DRST-AC, you will be guided through all parameters and you can choose the settings
which fit the application. For each menu there is a scrolling help text which is automatically shown in line 3 on
the display.
Configuration is carried out by use of the 3 function keys:
1
will increase the numerical value or choose the next parameter
2
will decrease the numerical value or choose the previous parameter
3
will save the chosen value and proceed to the next menu
When configuration is completed, the display will return to the default state 1.0. Pressing and holding 3 will
return to the previous menu or return to the default state (1.0) without saving the changed values or parameters.
If no key is activated for 1 minute, the display will return to the default state (1.0) without saving the changed
values or parameters.
