Recorder Functional Description MPI-540 meter can be used as a 3-phase recorder of power supply parameters. It allows measure- ment and recording of parameters of 50/60 Hz power networks such as voltage, current, power, har- monics values, etc. To switch to the meter to power supply quality analyzer mode, select Recorder on the main screen.
Page 123 The meter is compatible with PC software Sonel Analysis, which also supports other analyzers pro- duced by Sonel. This software allows analysis of the recorded data. The data may be read using the USB cable or directly from a microSD card after inserting it to an external memory card reader con- nected to PC.

National Metrological Institute. According to ILAC-G24 „Guidelines for determination of calibration intervals of measuring instru- ments”, SONEL S.A. recommends periodical metrological inspection of the instruments it manufac- tures no less frequently than once every 12 months.
Page 211 MEASURING MESSAGES NOTE! The meter is designed for operation at rated phase voltages of 110 V, 115 V, 127 V, 220 V, 230 V and 240 V and phase-to-phase voltages of 190 V, 200 V, 220 V, 380 V, 400 V, 415 V. Connecting voltage higher than allowed between any of the test terminals may damage the meter and cause a hazard to the user.
