VTPC-2 sector 2 current meter appears to be broken.
We tried to apply 100V to the chamber. Power supply tripped.
We tried two other channels at the power supply - still tripping.
We disconnected the TPC cable from the current meter, and the power supply was still tripping.
Finally we disconnected a cable connecting the power supply to the current meter (at the current meter), and then it did not trip.
We have no spares. We need to look for a replacement, or a new unit. |
