If i search for Agilent KOM PPC405 it show a few threads here The sad thing about the meter is the java version needed for the web page interface, mostly the instrument "web control section" says no java found but i'm at the latest v8 xxx version :( |
| HighVoltage:
If your Java version is too new it will not work. I had this problem on a different Agilent instrument and had to downgrade Java for it to work. I do not remember the details but it was totally stupid. |

I removed the one screw visible that was holding the shield in place, but looks like there are some hooks that go under the PCB. How did you manage to remove it? |

the shield plate if i remember slide the opposite way of the screw when it stop, carefully lift the plate |
