Nice unexpected feature is the oscilloscope works on the 10a ammeter setting.
First trial was to connect it to the 1khz 5v test output on my Owon labscope ---- no problems on AC setting nice square wave.
Next I tried to do a cranking voltage test --- At this point I hit on a snag the in both Multimeter and Oscilloscope modes it goes into straight into auto-ranging for both voltage and time-base with a lack of any user control for volts scale, also it behaves quite differently on the AC setting from the DC in DC mode it is definitely graphing meter in AC range it is an oscilloscope
On both the AC and DC scales the voltage ranges are 400mv (separate socket) and 4v, 40v and 400v on the main --- far from ideal for 12v light vehicle work. As a result was initially unable to capture a usable cranking voltage using the either the AC or DC settings. However using the DC settiing together a test lead I had made up for use with a Hantek scope with a capacitor to block the DC part of the signal I got a really nice usable capture.
I will do more tests over the next week or so and keep you guys informed.

I'm interested to see if you extract any more usefulness from it.
Thanks Andy

no brainer.
Tool of choice now for this type of job is CEM DT-337 clamp meter it has smaller jaws than the UNI-T UT203 I also use.
