No excuses, you need one of these.

Yes, we need a knowing person to do a video for us clueless plebs, just for MoHo stuff.
I've read be some of your posts Kev so Im not falling for the 'clueless plep' thing, you're pretty clued up😉. Ultimately IF anyone is in doubt they can post the problem and ask what to set the meter to, where to connect it and what to look for, that IMHO would be better than trying to cover a wealth of potential MH related issues in a lengthy video and ultimately failing, BUT people need to own the equipment first🥱
 
Looking on Amazon, there's a couple that look suitable, one of them appears to be a bargain! And of course you don't have to wait 6.weeks for it to come from China.

This next one is very cheap indeed at the moment, less than £15 AND it comes with batteries!!!
Maximum current is 100A which will be fine for everything except high inverter loads over 1200W ISH. Blinking bargain 👍

I'm okay with what I know Melrin but there is an awful lot I am clueless about, with 240 it's all pretty obvious with anything "I" would ever work on, I can even work on 3 phase if pushed, but 12/24v stuff is a nightmare, all cable and fuse sizes which you can work out online, but a meter is "for me" work of the devil, Continuity And voltage testing is my limit.

For instance I bought a pretty grotty mobility scooter last week and I am planning on converting it from Lead acid to Lithium, it came with two new batteries but the set up is a bodge, mine will be less so, if only in appearance, I can only see 3 wires, not sure what there is on the used battery holder as it hasn't arrived yet, I have two batteries to fit it already.
 
Continuity And voltage testing is my limit.
That'll be the case with most people because measuring current without a clamp meter you'd need an to break the circuit and insert the current meter 'in line' which is a right faff TBF. However with a clamp meter you just put the meter around the cable and no read off the current, it's just dead simple.
For instance, remember when you questioned whether your solar charge controller was MPPT or not? Well.a clamp meter on the SCC input and output would let you know in a few seconds.
 
I did once test for ohms on a Truma heaters gas valves, but I dunno how to do it now or test for resistance, well I say that but I've tested Liz and she has loads :( :(

I bought the COCZOW and it doesn't work :(

Reading 8A AC when the inverter was pulling over 70A. So that's going back lol.

Interesting to see if you still get your referral fee...

Well I dunno anyfin about a Coczow OR referral fees officer BUT I did notice that the Mustool doesn't display DC current correctly IF you use the Auto function, it auto selects DC current correctly BUT the reading is inaccurate. To read DC current correctly you have toggle through the options and manually select DC current.
Serves you right anyway.....I mean ....COCZOW! The clue was reading the brand backwards.
"I bought a Coc-zow but it Woz-Coc. 🤣

Try manually selecting DC current Steve and see if that does the trick 👍

LOL. I didn't see any way of turning the auto off, it's gone back anyway. I should just get a proper one ;)

Going by the feedback it's a common criticism, you don't appear to be able to manually select 😡.
Well done for being the Guinea pig though mate 🤭
 
@merl Which model of UNI-t?
This one, UT210E. I've had it for a few years now so I'm not sure if they still do the exact same model. As mentioned it only goes to 100A which was high enough until I went lithium/inverter/ leccy cooker. It's very sensitive on the 2A range, if you're careful you can detect down to a few milliamps, it's obviously not particularly accurate at these tiny currents but it'll pick up low parasitic loads which is very handy.

SO. AVOID THE LATTER AMAZON METER!
