    Measurement of alternating voltage The meter measures and displays alternating mains voltage in all measuring functions. This voltage is measured for the frequencies within the range of 45..65 Hz. The test leads should be connected as for a given measuring function. Measurement of voltage and frequency Set the rotary switch in the U,f position.

  • Page 24: Memory Of Measurement Results

    Memory of measurement results MRP-201 meters are equipped with the memory that can store 10000 single measurement results. The whole memory is divided into 10 memory banks with 99 cells in each bank. Thanks to dynamic memory allocation, each of the memory cells can contain different quantity of single measurement results, depending on the needs.
  • Page 25 The cell contains the measurement results of all types. After 5s the first result displayed. buttons to view different types of results. Select the bank and cell number (see section 3.2) or leave the current number. Then press ENTER again. The following screen appears for a moment, accompanied by three short beeps, and then the meter returns to display the last result of the measurement.
