This programmable true RMS multimeter has dual measurement capability and a dual display † which can show either two independent measurements, a measurement together with its range or a measurement with one of the many calculated functions available. The key features are: • Large, high contrast, liquid crystal dual display. • 0.04% basic accuracy, 12000 counts. • Manual or autoranging. • DC and AC Volts, DC and AC current, Resistance, Capacitance, and Frequency measurement; Continuity and Diode checks. • True RMS AC and AC+DC measurement. • Display nulling and Ohms null. • Touch hold mode - holds onto a stable reading until updated. • 100 point data logger. • Measurement post-processing to give: dB and power measurement with settable reference impedance percentage deviation from a user-entered reference linear scaling with offset limits comparison for go/no go testing automatic storage of minimum and maximum readings. • Remote control via addressable RS232 (standard) or GPIB (factory-fit option) interfaces. • Closed case software calibration. • Fully compliant with EN61010-1 Safety and EN61326 EMC standards. † Licensed under U.S. Pat. 4,825,392 2
