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.
