Digital meters Major technical parameter: 1.Basic error:0.5%FS±1db; 2.Resolving power:1,0.1,0.01,0.001 3.Max.display:1999; 4.display:Red digital tube 5.nput:Single terminal ; 6.Power supply:AC220V,AC380V,AC110V,50/60HZ 7.frequency;45 65HZ(to AC);C 8.ompression resistance;AC2000V/1min. 9.Spill display:1or -1; 10.Insulation resistance:DC500V≥20MΩ 11.Polar display:Only display-(to DC); 12.Weight;≈300g It is divided to economy digital AC ammeter and programmable digital AC ammeter, which is mainly used in the real-time measurement and indication on AC current of electric wiring. It can assort with all kinds of electrical quantity and non electrical quantity transmitter with linearity analog signal output of 0 20mA, 4 20mA and indicate the electrical quantity or non electrical quantity value in the primary circuit. Economy digital AC ammeter is only provided with the measuring display function. Feature: can change the measuring range through interior jumper; single instrument can support shunts with several different specifications; low price. Programmable digital AC ammeter is provided with several outputs of alarm, transmitting, communication and live programmable function except the measuring function. Eight shapes can be chosen freely. We can also produce the meters according to your drawings or models
