|
On May 16th 2013 the module was HV conditioned all day. As a result the maximum stable voltage has been increased to about 47kV (~4kV more than last
test). A maximum voltage of 49kV was achieved but the module was very unstable. Attached is the data from the testing. Note that occasionally the sparking
caused the PS to reset, it was turned back on and the voltage increased back to what it was (or lower) quickly. |

Remote end 9352 replaced with end 9764 due to signs of an issue with the tong cable (tong opening excessively large and slack in cable on one side).
Upon replacement tong opening on 9764 also opened larger then the remote end was set to. Everything is operational but this phenomenon indicates the handle
cable system on operator side must be where the excess is coming for. This is further indicted but the position of the locking screw on the handle cable |

Disassembled the master side of the right manipulator this morning to check the wrist cable. The cable on the master side shows no sign of wear or fraying
