Anyone got any ideas what might remove this horrible idiot graffiti on the panel? Isopropyl doesn’t touch it. --- End quote --- Yes, try using a dry marker pen, thats what I have used in the past. --- End quote --- Always read ahead before responding. You are a day late and a dollar short. :P :-DD --- End quote --- OK, go piss up a rope :-DD :-DD :-DD |
| Saskia:
graphite can easily be removed using fluorine gas. |
| Saskia:
as can Poettering. |

If you think that the manual is wrong, you can always ask the manufacturer. --- End quote --- I don't think so; the manual describes 3.000V as "full scale". ... --- End quote --- Please explain in details, why over-range data should be considered valid; thanks in advance. --- End quote --- It's not over-range. 3.1V is over-range. The manual mentions the frequency measurements over 200kHz have unspecified accuracy. Why not just make them over-range? Why not make 3.001V on diode test over-range? Why not mention that 3.001V to 3.099V are unspecified accuracy? I think 3.1V is full scale, and the manual is just wrong. I shall measure the VF of a string of diodes that reads between 3.001 and 3.099 on the F87 and see what a 6.5 digit meter says with a 0.6mA compliance current (the typical value for the F87 as per the manual). I'm betting it's within the accuracy specs for the 3.000V mentioned in the manual. |

More cleaning … haven’t had a 465B this good yet. Hope the IC works :-DD |
