• "Good small multimeter that measures capacitance! RS232 Interface Silly" by jonkoon on 7/9/2009
  4,000 Count 3-3/4 Digit Multimeter DMM w/RS-232
  Overall: 4.5 out of 5

  Quality:

  This is a great, small, affordable multimeter that measures voltage, current, resistance, and capacitance well (within the ranges specified). The only complaint that we have is the RS232 serial interface. The serial protocol is not well documented although we did discover the protocol via internet searches. The protocol does not return simple data as one would expect. It only transmits 14 bytes where certain bits within those bytes indicate the segments on the display that are currently lit up. No measurement values are returned, just screen display data. We did use this data to create lookup tables to measure data, but it just seems silly!
