All current measuring ranges are testing stations, manufacturing and QA. With a display equipped with a self-resetting, electronic fuse. range of 1,200,000, as well as exceptional accuracy and long-term stability, it fulfills all of the demands of Averaging Filter for Noisy Measurement calibration and R&D labs. A digital filter (1/2/4/8/16 measurement values) is used to smooth noisy measurement signals. Features Battery Charging Status – Power Saving Circuit True RMS Measurement of Distorted Waveforms Battery operation allows for mobile use of the The measuring method applied allows for waveform instrument for demanding maintenance work and independent RMS measurement for voltage and calibration tasks. An optional mains power pack can be current up to 100 kHz at crest factors of up to 10. utilized for stationary, long-term operation. If user selected, the device is switched off automatically if the Sampling Rate measured value remains unchanged for a period of The sampling rate determines the interval at which the between 10 and 59 minutes (adjustable), and if none of respective measurement value is saved to memory. the controls are activated during this time. Depending upon measured quantity and resolution, the interval can be set within a range of 0.01 s to 60 s. DKD Calibration Certificate The multimeters are furnished with an internationally Storing MIN-MAX Values to Memory accepted DKD calibration certificate (recognized by EA In addition to displaying the current measurement value, and ILAC). After the specified calibration interval has the minimum or maximum value can be continuously elapsed (recommended interval: 1 to 3 years), the updated and stored to memory at the selected sampling multimeters can be inexpensively recalibrated by any rate. calibration laboratory. Memory Mode Internal Clock The instrument is equipped with a 128 kB data memory with backup battery. The memory can be devided in 1 to Time format DD.MM.YYYY hh:mm:ss 15 blocks. New values can be written to memory, even Resolution 0.1 s after completion of a given measurement without loss of data, until the maximum capacity of 30,000 Accuracy ±1 min. per month measurement values is used. The data can be stored to Temperature Influence 50 ppm/K intermediate memory. The system records measurement values in relative time. Depending upon the measured quantity, the interval can Power Supply be set in steps of 10 ms, 100 ms, 1 s, 10 s and 60 s.
