Features: The YB5150Bi Digital Voltmeter delivers 0.56" high brightness 5 digit accuracy measurement with electrical isolation, specifically produced for dedicated voltages testing requiring external shunts beyond 10A ranges. Featuring a fully enclosed ABS housing and automatic polarity detection, this professional grades meter ensures stable ±0.05% accuracy after 3-5 minutes warming up for industrial grades reliability. Essential for electrical engineers, industrial maintenance technicians, and electronics professional working with high current systems requiring shunted voltages measurement solution. Optimized for accuracy voltages monitoring in power distribution panel, recyclable energy energy systems, and manufacturing equipment installations requiring 9999A capable shunt compatibility. Safety engineered with overloads protections and universal 75mV external shunt adaptability, this meter prevents burnouts through proper shunt implementation protocols.
