Option<br />
A special version of the <strong>E7800</strong> with DC<br />
voltage output is available. This unit is<br />
specified <strong>E7800</strong>-9x. The DC output<br />
voltage follows the position of the<br />
potentiometer.<br />
The output voltage (e.g. 0 - 1.0V,<br />
0 - 100%) can be reduced with up to 60%<br />
(e.g. 0 - 0.4V, 0 -100%) by adjusting the<br />
“Max. Limit Adjust” knob, placed on<br />
the rear side.<br />
An advantage of the design of the <strong>E7800</strong><br />
is that the potentiometer will<br />
“remember” its position, even when the<br />
supply is lost.<br />
