2|<h4>G-APD (med/max)</h4>
3Here the status of the bias system is summarized.
4
5The backround colors have the following meaning:
6<ul class='help'>
7<li>DNS online, MCP taking data, FAD taking data</li>
8<li>Bias voltage switched on and median current above 60&micro;A or
9maximum current (excluding faulty pixels) above 80&micro;A</li>
10<li>Bias voltage switched on and median current above 70&micro;A or
11maximum current (excluding faulty pixels) above 90&micro;A or any patch
12in OverCurrent or MCP not Idle and bias voltage is neither well defined
13switched on (VoltageOn) nor well defined off (VoltageOff).</li>
14<li>Bias neither ramping, nor in OverCurrent, nor in the well defined
15voltage on or off state.</li>
16<li>Bias crate is currently being calibrated</li>
17</ul>
18
19If the bias crate is currently calibrated asterix' are displayed, otherwise
20median pixel current and the maximum pixel current. The maximum excludes
21the crazy pixels. If a channel is on OverCurrent <I>(OC)</I> is appended.
22If the bias crate has not yet been calibrated the maximum current is
23replaced by a dash. If the bias current have been calibarted
24already, also the total power consumed by the G-APDs
25is displayed otherwise the median applied voltage.
