I have noticed that when doing a no-trip loop test with my fluke 1662, sometimes it will trip an RCD but then after reseting the RCD (no other changes) it doesn't trip again, I wonder if the fluke adjusts the current it uses for the test if it knows it tripped the RCD the first time round

Never had that with either the 1663 or the 1664, I should think your MFT is due a service?

It has recently been calibrated, strange maybe RCD having a sensitive moment
 
We kissed and made up
To be fair the posts reads 'dodger', not 'codger', even if 'dodger' was meant as a truncation of 'coffin dodger', is it offensive, I mean really? I can't see how it can be taken as such, And so what of you're playing limbo with the reaper's scythe, what is it of anyone elses problem? I mean you're being commended for not having carked it, not that the people is wishing you dead, the latter of course would likely offend.

(a)
This has to be better than the insensitive moment some have when they have not been operated for some time .. ( Or should THAT insensitivity be the fail )
As ever ... recommendations !

(b)
(Im a proud doffin codger .... is that the origin of old Codger ..?)
 
codger, coffin dodger. all just terms for us decrepit old fookers. i never take offence. a gate is easier to shift.

Multimeter or Multifunction tester?
MFT is a multi function tester
DMM is a digital multimeter
I was commenting on the fact that I have had both. I once took on the mighty Fluke company when I sent my IR temperature meter for calibration and it came back with certificate saying at 100 degrees it read 96 and at 0 degrees it read -4 degrees.
I boiled some water in a pot and it read 100 degrees then stirred melting ice in another pot and it read 0 degrees. I contacted them inviting their response to my findings and they said they would be coming down to where I lived in a few days and could I meet them there.
When they arrived they unloaded some kit and tested my thermometer again and the readings confirmed my results. They looked puzzled, so I pointed out I was at sea level and their company was in Johannesburg, 1,700 metres above sea level.
I asked them to send me another calibration certificate showing that my thermometer was reading correctly and they did.
They offered to sell me a high end calibration kit, but I declined saying that I understand the relationship between specific gravity and temperature, and had a pot to check my IR thermometer with.

fluke been used since 1992 very good multimeter
My previous post was directed to Sparky55 who may not know the difference.
 
Sorry, still new at this, thought it was an open thread

All posts are welcome. Worth checking if people have replied to a particular post though - it will be highlighted with an orange box - just to get the context of things.
 
Metrel 3102BT upgraded from an old and trusted HT Italia combitest 2019. Partially because I bought the Metrel EV charger with it as the total deal was at a special price
Use a Metrel 3309 Delta PAT for the appliances
 
I have a 3 piece Robin set , had it over 15 years now

Still have that set

The 3-wire fault loop impedance is a great test meter for sockets

Is it all 2-wire loop testing now or is 3 wire still used
