Applications
The wireless clamp tester is available with a measuring range of 0.00mA-60A AC. The clamp ammeter is especially suitable for places with dense wiring (power metering systems, high-speed rail systems, automotive circuit maintenance, etc.), and non-contact current measurements to ensure safe operation. The instrument is small in size, high in precision, stable in performance and perfect in function, and is one of the necessary tools for electrical safety inspection and maintenance.

Tips: How to use a clamp meter?
When using a clamp meter to detect the current, be sure to clamp a measured wire (wire). If two (parallel wires) are clamped, the current cannot be detected. In addition, when the center (core) of the clamp ammeter is used for detection, the detection error is small. When checking the power consumption of home appliances, it is more convenient to use a line splitter. Some line splitters can amplify the detection current by 10 times, so the current below 1A can be amplified before detection. Use a DC clamp ammeter to detect the DC current (DCA), if the current flows in the opposite direction, it will display a negative number. This function can be used to detect whether the car's battery is in a charging state or a discharging state.
