Manasa and Raji hooked up HV power supplies to the PZTs and set them to the middle of their ranges (75 V).
|
[Raji, Manasa]
The high-voltage power supply from the OMC was removed to replace one of the PZT power supplies. The power supply terminals were connected to the rear connection ports as per instructions from the manual (TB1 panel: port 3 - (-)OUT and port7 - (+)OUT). They were both switched on and set to deliver (75V) to the PZTs.
