Dear tthm_w,
Thank you for your reply, you're right, it detects both and indicates "AC" or "DC"................................ eventually.
So I can use it to monitor and speed up the discharge to a safe level of DC circuits so I don't get a shock when rushing fault-finding, so I am relieved 'cos I expected this feature when I bought it, DC Low Z's super useful.
The time the meter takes to read is excruciating, 2 seconds at least, and won't work much under 12V, when a 12v Car or SLA battery is a bit flat it sees nothing, LowZ's no good for automotive and leisure/camper use (I didn't expect it to be really, LowZ's primarily for 50+ volts applications I think, please correct me). 2 years ago whilst faultfinding van electric windows for a mate, when pressing the window buttons it wouldn't read anything in this mode, now I know why, either not enough volts or too short a press.
Ultimately I wanna know the limitations of each feature/mode so I do not make bad measurements and waste time chasing red herrings. The 12V limitation is explained in the manual, OK, but only mentions it does AC so I though LowZ on this meter was limited to AC exclusively. But 2 or 3 seconds
Whilst the firmware is fine then, the manual is where an overdue revision is required.
6 years after the meter came out, the feature set/ manual is still not clear, I confess that I have come to not trust this instrument.
Fluke's the way.
