\subsection{High voltage test}

\begin{compactitem}
\item Look up cable length for drift and anode.
\item Prepare the ends and label the cables on one side.
\item Solder the side without label to the hv filter box, drift on the
right side (blue), anode on the left (red). Disconnect the return
cable (yellow) and isolate it.
\end{compactitem}

\begin{compactitem}
\item Solder the labeled side to the test box.
\item Connect the test box to the hv modules. Use the two channels (red for anode and grey for drift) connected to the ampere meter.
\item Remotedesktop to hv03 and start the PVSS project \inputcmd{hv\_trd200711}.
\item \inputcmd{ dimcat A310.CH0.I A310.CH1.I} on trd01 and observe the currents while testing.
\item Restart dimcat, if needded, with \inputcmd{ssh root@daq00: /etc/init.d/a310 restart}.
\item Take care that the current does not increase over 5$\mu$A.
  \begin{compactitem}
  \item Voltage: drift = 2000 V and anode = 1400 V
  \item Current: the value should not increase above 1 $\mu$A. After the ramping process the currents should decline below 300 nA. Wait 10 minutes and observe the current. It should not ascend. If the current is higher than 300nA after ramping, observe the chamber a longer period of time.
  \end{compactitem}
\item If there occures a current trip or the current is to high, it is possible, that one cable in the hv filter box is broken. Discover it, repair or replace it.
\item Reconnect the return cable.
\item Measure the drift resistance with the blue channel, that without ampere meter. The value should be 12.7 M$\Omega$.
\item Note the results.
\item Fix the cables with a cable tie on the left side at the filter box. Close the white plastic box.
\item Put a paste-on label with your initials and date of testing at the chamber.
