The box came very crumpled. But inside, the whole thing works. Thanks!
LOW QUALITY BUTTONS. DISPLAY HAS TOO LOW RESOLUTION. IN ITEM DESCRIPTION ALL PICTURES ARE OK, BUT IN REALITY IT IS NOT SO ACCURATE. IN HIGHER FREQUENCIES ACCURACY IS MUCH WORSE. LONG DELAYS TO SWITCH BETWEEN MODES. FOR MEASUREMENT ONLY AC MODE WORKS, FOR EXAMPLE CAR MOTOR HALL SENSOR. IN DC MODE IT DOES NOT DETECT PULSES.
