The analog electronic multimeter PM 2505 is a universal measuring instrument with 62 measuring ranges. With the optional accessories the measuring ranges can be extended up to 77. The PM 2505 measures: - ac and dc voltages from 100mV f.s.d. to 1000V f.s.d. - resistances with a linear scale from 100£2 f.s.d. to 30M£2 f.s.d. - ac and dc currents from 1 jUA f.s.d. to 10A f.s.d.. The ranges in the voltage, resistance and current functions are divided in 1-3-10 steps. Separate ranges are available for testing semiconductors ^ 1 and for continuity check with the aid of an internal buzzer ^. The instrument is powered by two 9V batteries which enable continuous measuring for at least 1000 hours.
