Voltages, current and resistance outputs seem ok, but the thermocouple output is complete garbage, it has no voltage stability at all so the output constantly fluctuates by 2 to 3c at a constant rate, checked this also with an oscilloscope to check the output and it has a constant pulse every 100ms making it useless for testing whether a thermometer is reading correctly from a thermocouple output, the pulses cause the thermometer to jump every 1 second or so, so you are unable to even use it to verify a thermometer (I have various fluke and digitron thermometers that I could not verify because of the unstable readings). I don't think I would recommend this device because of its flaws, there are other devices available that do a much better job than this one for about half the price.
