I replaced the low current range fuse with a resetable one for this exact reason: https://uk.farnell.com/c/circuit-protection/thermistors/pptc-resettable-fuses

You can get low range current clamp meters, however because you're measuring DC current they will not be as widely available as the AC versions.
Something like this would do:

Maybe worth contacting the site sponsor test-meter.co.uk and see if they can recommend something for you. You also get a discount for being a member.
My fluke doesn't need leads changing for any tests
Fluke 116, hopefully it will do what you need I've been impressed with itWhich fluke is it I’ll have a look
The Fluke 116 only measures up to 600 microamps (AC or DC). i.e. 0.0006 Amps. That is while the rotary switch is adequate. It won't suit here at all!Fluke 116, hopefully it will do what you need I've been impressed with it
Ok alasdair calm down only trying to helpThe Fluke 116 only measures up to 600 microamps (AC or DC). i.e. 0.0006 Amps. That is while the rotary switch is adequate. It won't suit here at all!
Sorry - I felt calm enough at the time! Few glasses of home-made red wine inside now and I am certainly calm. The 116 is an unusual meter for electrical work - more an electronics multimeter. In fact I was amazed that it only goes to 600 microamps.Ok alasdair calm down only trying to help
i am hoping you may be able to help. I’ll try to explain my problem, any help gratefully received.
Part of what I do is train fire alarm engineers and as part of the practical is battery calculations, which we need to measure the stand by and full alarm load off the battery leads.
So the process is swap leads to mA position and switch to mA reading, connect leads in series to the battery disconnect main power so now mA is displayed for stand by the press sounder button on fire panel and you have alarm load.
Despite every time explaining not to do anything different & not to do it until I say etc etc nearly every course some one will either not change the leads or something stupid and bang as a minimum fuse blown.
What I am asking, is there a multimeter that does not need leads switching or as some sort of non fuse blowing feature that will allow non listening people to not blow meters?.
There are meters with an 'alert' function, that makes a beeping noise and/ or flashes up 'LEAD' if you select a voltage range with red lead still in the current socket. Of course, if you also leave the meter on a current range and try to measure the voltage, that's no help.
But what are these people doing? I swap the leads on mine from current to voltage many, many times a day, every day, and haven't made this mistake for a decade or more. You need to drill into them the significance of checking the connections and settings for every setup bar none.
It's a good job they aren't trying to use a vintage valve tester. You can destroy a valuable AVO VCM instantly (beyond economic repair as the special panel meters haven't been made for years) just by turning one of its dials one click too far. FWIW the girls who used to help out on a Saturday never seemed to have any difficulty using them accurately.
how do I stop them doing their first and last time at my expense ️️Lol

Rob you are a genius, the meter arrived today, it works an absolute dream. Had to come from USA and was a bit pricey but no more students blowing multimeters up.
Thank you.

No problem, like I mentioned though I'm sure someone @Test-Meter could have gotten you an equivalent from the UK with a forum discount applied too.
Maybe worth baring in mind if you need more for your staff.
Now I know it works I will try find in uk, I did message them regards one of their clamp meters to see if it would do the same, they just sent back a data sheet didn’t answer my question sadly
Rob have a look at
AEMC CM605 Low Current AC/DC Clamp Meter (100A) - https://www.test-meter.co.uk/aemc-cm605-low-current-dc-clamp-meter/
Looks fairly much like the same unit maybe re badged.
If it’s the same as the amazon one it would fit the bill. Checked the amazon one against my new calibrated flukes and it was within a few mA.
