Title: BBC Goerz Metrawatt, Test leads KS21 ( 1980 Kabelset )
Post by: Kiriakos GR on November 15, 2018, 07:07:37 PM

This is a topic which I am writing so to present pictures of original test leads for many BBC Goerz Metrawatt analog multimeter of 1985
Ident Nr. GTY 362 0035 P01

History it did record that this generation of  BBC Goerz Metrawatt analog multimeter was and is high-end meters of that era all designed for professional use.

My very own MA4S this is industrial version, but when I got it as used I did not receive original test leads, and I was unaware of how they look like.
Some one on eBay demonstrate pictures of these KS21 test leads and this was a great opportunity for me which I now share for you to see.

Practically all test leads of our century they are much better and more safe to use, I do not deliver either any buying recommendation for this ancient  ( 1980 Kabelset ).
But it is nice to see then just of curiosity, in the end of the day they are production sample of our Europe when this was not lazy and producing it own test leads.

Regarding electrical specifications, these leads they should handle 750V AC/DC and 25A with out time limit.

BBC Goerz Metrawatt, test leads of that era.
They were made as custom work by Hirschmann Germany.

When KS21 test leads, these were damaged? and or longer wires was required, next close replacement this was Hirschmann measuring cable series.
These have molded banana plugs in both ways, these are secure to handle up to 1000V.

Actual wire diameter isolation 4mm
Inner copper  (2,5 mm²) / 32 A

For such analog multimeter, Metrawatt considers as essential wires diameter to be large.
This improves multimeter accuracy, especially when the multimeter measuring current, from uA up to 25A range.

Note: Modern test leads, they support up to 10A as Max, and they are compatible up to a point.
But all analog multimeter characterized as Low impedance, they need higher diameter of test lead wires.
