INTRODUCTION The B & K Precision Model 830A Autoranging Capacitance Meter gives a direct reading of capacitance on a 3-% digit crystal display. The autoranging feature automatically selects the range with the highest resolution. Ten full scale ranges of 199.9 picofarads to 199.9 millifarads include virtually all capacitors used in electronics equipment. A selectable hold feature prevents the range from resetting when a capacitor is removed, for faster batch testing of large value capacitors. The instrument has application in electronic engineering labs, production, service shops, and schools. It can be used to check tolerance, sort values, select precision values, measure unmarked capacitors, select matched sets, and measure cable or switch capacitance. Its battery operation, light weight, and small size make it a truly portable instrument.
