Abstract :
Introduced at a price of only $269, complete with battery charger and belt carrying case, a handheld digital multimeter is one of the few recent portable instruments to come along with the capability of measuring capacitance. The model 21 also measures ac volts, dc volts, and resistance. It includes the following specifications: four full-scale ranges of dc volts from 2 to 2000 volts with 1-mV resolution; four full-scale ranges of ac volts from 2 to 2000 volts with 1-mV resolution; four full-scale resistance ranges from 2 to 2000 k¿ with 1-ohm resolution, and four capacitance ranges from 2 to 2000 nf with 1-pF resolution.
