3-348-979-03 7/7.11 GMC-I Messtechnik GmbH METRAHIT 30M Precision Digital Multimeter DIN EN ISO/IEC 17025 DQS certified per DIN EN ISO 9001 Reg.No.1262 QUALITY MANAGEMENT SYSTEM Applications The 30M multimeter is a high performance, precision measuring instrument for RD labs, industrial applications, universities, gov- ernment authorities, testing stations, manufacturing and QA. With a display range of 1,200,000, as well as exceptional accu- racy and long-term stability, it fulfills all of the demands of calibra- tion and RD labs. Battery operation allows for mobile use of the instrument for demanding maintenance work and calibration tasks. An optional mains power pack can be utilized for station- ary, long-term operation. Features TRMS Measurement for Distorted Waveshapes The utilized measuring method allows for TRMS measurements for up to 100 kHz at crest factors of up to 10, independent of the waveshape. Sampling Rate The sampling rate determines the interval at which the respective measurement value is saved to memory. Depending upon mea- sured quantity and resolution, the interval can be set within a range of 0.01 s to 60 s. Automatic and Manual Measuring Range Selection The desired measured quantity is selected with the rotary switch. The measuring range is automatically adapted to the measured quantity. The measuring range can also be selected manually. Averaging Filter A digital filter (1/2/4/8/16 measurement values) is used to smooth noisy measurement signals. Storing MIN-MAX Values to Memory In addition to displaying the current measurement value, the mini- mum or maximum value can be continuously updated and stored to memory at the selected sampling rate. Continuity Testing Continuity testing allows for the detection of short-circuits and interruptions. An acoustic signal can be generated in addition to a visual display. Overload Protection The instrument is protected against overloading in all measuring functions. All current measuring ra
