SMAKN Digital Voltmeter Ammeter AC 130-500V 100A Voltage Ampere Multimeter
Measuring range: AC 130-500V; AC 0-100A. Accuracy: 1% +/- 2 digits. Measurement speed: about 2 times/seconds. Working mode: voltage and current dual display; 2-wires. Color of housing: black. Display: 0.39 inch LED digital tube display, voltage - red, current - green. Dimensions: 70mmx40mmx30mm. Installation size: 68x38 mm. Transformer inner hole: about 11 mm. Features: Split type: easy installation, can be separated from instrument transformer, transformer based on the actual location of the need to install (could be longer transformer secondary side lead, in order to achieve the ideal installation location). Dual display of AC voltage and AC current in the same time. Instrument wiring is simple: Two wire system: no other power supply, red, black line by measuring the voltage at the same time to power a header (without polarity). Current test without having to purchase another transformer, instrument with high precision transformer. Within the header l trimmer potentiometer, can the calibration error of voltage and current. Split type header with a back cover of transformer, use rise more secure, more convenient, more comfortable. Note: The instrument connection order is: first meet current loop line, finally connected to 220V voltage, on 220V power supply, can not touch the back of the instrument of any components and circuit, to prevent electric shock risk. This table using capacitance step- down principle design, because of the higher frequency capacitance impedance is smaller, so weak in the high frequency electronic speed, non sine wave frequency, electric, or other places that have requirements of high frequency components, otherwise easy to burn.
