Elma BM811 Elma BM817 Elma BM515 - Elma Instruments

Elma 811 + 817 + 515 side 66μA, mA, and A current functionsDefault DC. Press the SELECT button momentarily to select AC.*Note: When measuring a 3-phase system, special attention should be paid to the phase to phasevoltage, which is significantly higher than the phase to earth voltage. To avoid exceeding thevoltage rating of the protection fuse(s) accidentally, always consider the phase to phase voltage tobe the working voltage for the protection fuse(s).RS232C PC computer interface capabilitiesThe instrument is equipped with an optical isolated interface port at the meter back for datacommunication. The optional PC interface kit BR81X or (BC81X RS232C optical adapter cable +BS8151X RS232C software floppies) is required to connect the meter to the PC computer. TheBS8151X RS232C Data Recording System software has a digital meter, an analog meter, acomparator meter, and a data graphical recorder. Refer to the README file in the interface kit forfurther details.
