Features:<br> High accuracy dual- display, the display is bright and for sharp.<br> Voltage and current power measuring instrument, which can only measure and display the voltage, current and power- of the circuit under test-.<br> It can be adjusted by adjustable resistance to fine tune the display value. It does not have the function of lifting voltage or limiting current regulation, so it does not affect the actual voltage and current of the circuit under test.<br> Wiring: red cable for positive, black cable for negative, non-connection when testing loop current.<br> Fine-tuning for voltgae & current display, no- load current does not return to zero-.<br> <br> Specifications:<br> Material: ABS <br> Operating voltage: 6-120V DC-<br> Range:<br> Voltage measurement range: 6-120V,10V- below display mode 0.0V, voltage 6.00V jump, error range 1V<br> Current measurement range 0-10A, current 0.03A- jump, error 3%<br> <br> Note:<br> Please allow 1-3cm error due to manual measurement. pls make sure you do not mind before you bid.<br> Due to the difference between different monitors, the picture may not reflect the actual color of the item.<br> <br> Package includes:<br> 1x Digital Ammeter Voltmeter
