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...
Well I must admit I've used better scopes. I'm a mecanic teacher and the school o work for own 3 automotive picoscope which are amazing but expensive. 700$ each (unit only) & 1200$ each with all the accessories. The 6022be is way far behind these picoscope but for less than 100$ they can do most of the job I need a scope for.
If you compare this 6022 to the picoscope you'll be disappointed but if you can live with the fact that it's slower, the software is ( no harm to Richardk . he has done a wonderful job ) way behond what the picoscope software, it worth the 100$ you'll spend.
Like I said, I use it often for rotation signal. ( engine speed , abs sensor...) These signal are pretty much always below 5volt so it works right of the box. When you get to ignition & injection, you'll need a 10x reducer for injection as youll reach peak ay 40v or so. And even a 100x for ignition as you get peaks at +/- 300volts.
The software of the 1008c is more "automotive" ready as they integrate preset such as amp clamp for starting, charging, compression check , injection & ignition ramp.
The 6022 software only have voltage measurement preset so you'll have to do the convertion by yourself. But in the end you'll get to the point.
For the probes, in automotive diargnostinc we usually use voltmeter type probe with back probes (needles to get between the wire and the plastic connector).
Also the ground clamp need to be bigger and have a longer wire.
Anyhow, I guess you get with you pay for and the 6022 worth every $ if you are ready to work a little harder.
I haven't try the 1008c , I only used the demo mode on the software. I plan to buy one in the next months.
