This digital multimeter by Velleman measures AC and DC voltages up to 600 volts, DC to 10 amps, checks diodes and transistors, and has 5 resistance ranges. Measure the hFE of any transistor from 0-1000. When you push the hold button, the meter will retain the last reading until the button is pushed again. The meter is encased in a yellow rubber holster. Oh yeah, did I forget to tell you that the meter has a back light for the LCD display. The meter is fused and powered by a 9 volt battery.
