KMV 01U Voltage Frequency True RMS Digital Multimeter

      KMM 01U is very advanced multimeter which gives user precise readings in 4 digits and seperate CT ratio adjustments for
flexible systems. It is not only measures the current pulled from the L1, L2,L3 but also voltage and frequency of those lines in True RMS.
      There is 5 rows for measurement digits. Three for the currents that are showed continuously, one for the voltage that is cycling every 3 seconds (VL1,VL2,VL3,VL1-L2, VL1-L3, VL2-L3) and one for the frequency of the line voltmeter shows (between phases shows the first phase’s frequency).

      Measures very accurately, the voltage value of the line (AC+DC) in True RMS. The values measured shown every 3 seconds (VL1,VL2,VL3,VL1-L2, VL1-L3, VL2-L3)in a cycle. If user would like to observe any of the lines value, the only thing is to select the desired value, it will show selected value for 60 seconds continuously, than begins to cycling again.

     Shows the frequency of the line that voltmeter shows. When the voltmeter shows between phases values it shows first phase’s frequency. For example : If the voltmeter shows L2-L3 value frequencymeter shows L2 frequency.

      By pressing the MENU () button on the front panel, desired current can be choosed, then CT ratio of the current shown; by pressing () adjustment digit is choosed and by pressing () adjustment can be done. For saving adjusted value, just waiting for 5 seconds is enough.
