has introduced a unique 4-in-1 meter for the first time. It has simultaneous measurements of Volts, Current, Frequency and Power Factor (Single phase and three phase balanced load.) This reduces the cost of using 4 seperate meters and saves space on the Panel. Wiring of cables is also reduced thus effecting tremendous saving in cost. 4 in 1 Display Rescaleable Facility for Volts, Amps, Frequency. High Accuracy and Stability. Small, compact in size. Micro controller based design.   SPECIFICATIONS DISPLAY RANGE ACCURACY VOLT 110, 220, 440 (anyone) 50Hz ±0.3% + 4digits CURRENT 0-1, 5A (anyone) 50 Hz ±0.3% + 4digits FREQUENCY 40 - 99.99 Hz ±0.1% Hz POWER FACTOR 0.2 (LEAD) - 1.0-0.2 (LAG) ±2° ELECTRICAL       MODEL  RPFM-11, 96 RPFM-11 SINGLE PHASE ONE ELEMENT  RPFM-31, 96 RPFM-31 THREE PHASE ONE ELEMENT (BALANCED LOAD)   Note: Volt Span: Rated Voltage  ±15%, Current Span: 20% to 120% of rated value  Insulation Resistance  : >20 MΩ at 500V DC  Operating Temperature  : 0 to 50° C (RH, <70%)  Auxiliary Supply*  : Self Powered  Dimension  : RPFM-11 RPFM-31    :96X48X110   96RPFM-11, 96RPFM-31:   96X96X110     *Meters with Seperate Auxiliary Supply are also available.   DIMENSIONS
