No Signal at Cn
When no current is measured on the Cn channel
although the HV is applied then the HV is
switched off.
Check if the coaxial cable at the Cn plug sockets
on the rear panels of the 2830 and 2831 is well
connected. A further reason could be a short
circuit or a flashover in the test cell.
No Measuring Signal
When after a few seconds no signal is detected
on the measuring channel Cx then this error
message pops up. By clicking on Yes, the
measuring will continue, by clicking on No the
HV is switched off and the measurement stops.
Check if the test cell is connected to the plug
sockets “a” and “U” on the front panel of the 2831
and the connection between the plug sockets
“Cx” on the rear panels of both units.
