Where is that 87V now anyway?
Where it gets much better care than it ever did in my hands.
Do it Joe, do it.
You're not the only one wanting to see this.
Not to spoil the outcome, I have not run the high voltage test yet but I have ran the AMPROBE AM-530 all the way up to 5.9KV (max output). Keep in mind that the AM-510 was in the finals with the Fluke 101. Both companies owned by Danaher so I was not too surprised. But as I continued to test the 530 at higher voltage levels, it never gave any signs of an arc. Also, once it was damaged, it never really got any worse like all of the other meters. It still read DC and AC voltages just fine. So rather than try and finish it off, I thought it may be more helpful to some of you if I actually attempted to repair it.
I did a quick check and when in ohms, I could see the output was working but the input was loaded. There is only one part in this node, Q9. This is an H1A. I pulled it and sure enough, it was damaged. Installed a new one and all of the modes appeared to work. The meter was never all that accurate, so I went ahead and aligned it. From what I could tell:
VR1 sets the DC offset
VR9 sets the AC
VR6 sets the temperature
VR7 sets the capacitance
So if you happen to over voltage your AMPROBE AM-530 by accident and the ohms, diode and capacitance modes no longer work, check Q9.
And for the few of you actually following this thread, here is the 5KV testing. It's long but there is some damage for everyone to enjoy.....
