WY2174A AC Millivolt Meter (Digital Range Switch)Detailed product description：

Characteristics of WY2174A AC Millivolt Meter:

◎ Wide measurement range: Thirteen levels with a range of 30 μ V to 300V
Low local noise: ≤ 5 μ V, the highest level in China
◎ Wide frequency: 5Hz-2MHz, measured up to 5MHz
High input impedance: ≥ 10M Ω, high impedance is the foundation for ensuring correct testing
◎ Friendly human-machine interface: Soft digital range switch, circular arrangement LED clear display status
Durable and long-lasting: No worries about misalignment and slipping, input protection and output current limiting, and no overshoot of the electric meter.
This machine also has a common ground/floating selection, making high voltage measurement safe and micro voltage measurement accurate. This machine will be the first choice for audio engineering, college electrical engineering, electronic laboratories, and analog signal testing.
