Workshop Project #34 Fluke 5100B

Now what did I get myself into now?! I was browsing ebay and looking for some affordable that is below 5 digit including delivery solutions for reference voltages and currents; as in calibration refrences for my ever growing multimeter collection. So that they at least agree to a certain degree and are close enough to a real absolute value to comfortable switch between them during repairs.

Now the only affordable model I found was a Fluke 5100B calibrator. It can deliver AC and DC current and voltages in a rather broad range: from millivolt to 1100 volts and microamps to 2 amps. Both in DC and AC. There was a problem with the delivery though and I still think that the company behind ebay global shipping service should compensate me for the additional cost in replacing the cheaper one of the two devices that they lost in transit... seriously: how does one loose a 40kg package?

This one the second best offer I found required some "close your eyes and click buy now" and my wallet feels considerably lighter now. Let's see what I got and how well it works... or not!
