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?

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.
 
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.
