To find out if it's working, Tunnie, you'll need to find 40,000 volts. I suggest climbing a pylon. 

 
I suggest setting the twiddly knobs up first.

Careful you'll get an "'ell of a belt off that!!!"   

[TheBoy]

TBH its worth jack .

Not a great make, old, and big and bulky.

Probably worth keeping for that time you may need one

The 40kV probe would be useful for looking at ignition pulses.

Hadn't thought of that, could be good for diagnosing faulty coils on kitty

[Diamond Black Geezer]

would it handle Xenon HID levels of current/power? (terminology probably wrong)

What would you want to measure?

[Diamond Black Geezer]

I dunno, it's an oscilloscope. I'd just want to find something to plug it into to make the line go all wibbly-wobbly and go 'wooooOOOOooooOOOoooo'. 

[STEMO]

Well it won't go wobbly with a constant DC current.

Err - if I were you I would wait till someone else shows you how to use the 40KV probe, for two reasons.

1) If you do it wrong, Poking away blindly at those kind of voltages could easily put you in hospital - either in the wards or in the mortuary.
2) Someone else gets the belt if the probe is faulty. 

If you just want a wobbly line, take the standard x10 probe, crank the voltage knob down to a few volts and hold the tip of the probe in your fingers. You should see a 50Hz signal on the screen - it's your body being used as an aerial and picking up the mains.

Crank or cam sensors, or the ignition output. If you know what you're looking at it's a good tool for efficient, accurate diagnosis.

A scope is not something I would go looking for, as I don't have any use for one.

Maybe something for the garage loft then, pull out when needed

Wow! Makes me want one now 

[STEMO]

Try measuring your own resistance, don't need a fancy osc. for that.

Probably best stored somewhere drier than a garage, or it'll just fizzle a bit and let a little smoke out when you do come across a need for it.
