oh.. I always used this for rotation signal (engine speed , wheel speed sensor.....) and these signal are often below 5v... I didn't know it was limited to 5v.
by the way i'm not using the original probe (since these are not appropriate for automotive testing) I'm simple probe without the x10 switch attached to it. So if I put the software in x10 mode , i'm not getting the right voltage either.....
any solution ?
I could always mod the original probes that come with the scope.. is this the best I can do ?
Yeah, the software in X10 will just multiply the value of the input voltage by 10, but the input voltage value is clipped at + or -5V, so you'll still get the wrong voltage. You need to have a X10 probe to see signals >+-5V, so probably modifying the original probes is your best bet.
Might be a stupid question, but what makes the probes unsuitable for automotive work?
is it just that alligator clips are better?
how is the scope for automotive work?
are there enough channels for everything that you'd want to measure?
Hantek appear to do another scope (1008C) that has a bit better resolution (12bit) and more channels (8 instead of 2), but a much lower sampling rate - 2.4MS/s rather than 48Ms/s, which (I think) gives it about a 1MHz bandwidth...
I've been considering getting that (1008C) scope with more channels to go alongside this one (6022BE), mainly for doing audio stuff, but would use if for automotive work in the future...
