Same function=AC DC current/AC DC voltage/Resistance/Capacitance/Frequence/On-off beep/Diode test/Auto Range
Difference Comparison
Suggestions
UT61A: If your working environment is dark, UT61A is a good choice, it with buzzer indication,Transistor test,EF(electrical field) detection,bring you different functional experience
UT61B:Based on UT61A,add temperature measurement,RS232 data transimission function ,but without buzzer flash indication,Transistor test function,EF detection
UT61C:Higher precision than UT61A and UT61B
UT61D: With True RMS function
UT61E: Excellent precision, better than most of multimeter in the market,Max display count 22000, but without backlight and auto power off function
