| screensaver for Keithely 2000? |

Hello my friends, I would like my Keithley 2000 to switch screen off (either manually or after inactivity) to preserve the VFD. I don't want to switch the whole unit off because of warm up. Has anyone implemented this yet? |

You can blank/turn off the screen using GPIB. |

And ideally I'd like to have this feature not depend on GPIB and external programs that I would need to run every boot. But looks like there is no easy way so far. |

You don't need GPIB, you can use the RS232 port. A very cheap serial to USB converter is all that is needed. We are talking <$5 here. I don't understand why you need to keep the meter switched on all the time unless you are doing some data logging, in which case a serial or GPIB would be required anyway? Also, the Keithley 2000's are notorious for "screen savers" anyway because without any input they just blast through every possible digit on the VFD due to the extremely high input impedance. It's part of their charm, if you will ;) |

VFD displays have two wearout mechanisms. The first is filament degradation (blanking the display will not help this). The second is phosphor degradation. Blanking the display will help this. Phosphor degradation seems to be the most prominent. I have a lot of equipment with weak VFDs, but segments that are not usually lit are still nice and bright. |
