Absolutely great and accurate
Outstanding quality. High accuracy. Has great ergonomics and usability.Temperature measurement was in correlation with other references and spot on.CREST function works great. MIN/MAX/AVG, frequency check can also be done using MIN/MAX/AVG button,AC+DC measurement was spot on and fast when checking rectifies, DC is very accurate, hold and relative function works really well, AutoHold makes repeated measurements when tracing stable voltage presence a walk in the park. On mV range use of third party AC current clamp on 1mv/A range have yielded very good if not excellent results. The measurement via this clamp of a small current ranging from approximately 10mA(!) (and up to 600mA) was spot on and this really helps to trace small power consumption on AC mains for e.g. Continuity fast, ohms, diodes,capacitance checks are fast and accurate. It has some limitations on mV AC range 600mV (and note it looks like it DC coupled and signal must not be more than 1000mV when measuring otherwise results are not to be used on this range of mV (only) it reflected in manual) Leads could be a bit better - these have no notches on sharp(very) ends and this makes a bit difficult to hook up wires to them when needed for e.g. oscilloscope retracted hooks do not hold well on them, but this is not a big issue and having another pair of leads for these particular measurements situations solves this. Batteries compartment designed seems very well. Meter is very sensitive to EMF around when measuring resistance around 670kOm range this needs to be taken into account, however AutoHold helps and reading is within spec. Can be improved a bit in terms of buttons would be nice to have them highlighted, also would be nice to be able to upgrade firmware yourself, and would be nice to have option between light and just red diode on the meter panel flashing in continuity check etc Overall it absolutely excellent and you can trust the measurements (even with small issues it may have).
