JW－**0A
General
This device is a new product developed for the market demand, which, with the output current up to **0A, can work continuously for a long term.
Based on JW****7, this product has additionally the function of direct testing of DC voltage. The device can give a measurement result when a tester simply connects the resistor to be tested (shunt) to the circuit according to the four terminals method, selects an appropriate current range from 0.5A～**0A as per the current allowed to pass by the resistor to be tested (shunt) and raises the desired current value. When the output value is the range rating, the measurement accuracy is 0.*5%.
The device, equipped with a USB or RS***2 interface, can be operated by the PC, working stably and reliably.
The display uses a 5.*-inch color LCD screen, and the chart characters are displayed clearly.
