I just got a very good deal on a Fluke 123 Scopemeter. I charged the NiCd batteries on an external power supply and everything seems to be working.
It does not have power supply. Does anyone knows what type of connector is used for the power supply? Or if someone could measure the lenght and diameter of the metal barrel. I believe, the diameter is about 5mm (5.4mm) but I don't know the length, the hole on the meter looks quite deep. (total depth about 22mm, inner barrel depth about 10, so I guess the barel lenght should be >= 10mm if the plastic part can pass through the outer hole).
On the power supply data sheet the connector is specified as DIN45323, 5mm OD.
On more question, the original power supply is for 15V. Would it be possible to use 12V supply? I have plenty of those.
The battery is almost dead, so I will replace it with NiMh (or maybe later with Li Ion as was described in a recent thread).
