5Hz-2MHz) Digital AC Millivolt MeterDetailed product description：

The WY1971D digital AC millivolt meter (5Hz-2MHz) is an upgraded product of the original WY1971. It is an intelligent digital instrument based on CPU control and can measure the effective value and corresponding level value of sine wave voltage with frequencies ranging from 5Hz to 2MHz. The voltage measurement range is from 30 μ V to 1000V, with a resolution of 0.1 μ V, which is the highest level in China. Specially designed LCD screen with menu style display of multiple parameters and dynamic pointers for range automation.
