AS2294D Dual channel AC millivolt meterDetailed product description：

AS2294D dual channel AC millivolt meter: gentle digital range switch, durable: no worries of misalignment and slipping, dual pin display on the same meter Input protection and output current limiting, the meter is free from overshoot Automatic zeroing function, touch the key to select synchronous/asynchronous operation. During synchronous control, both left and right switches can control the range, and the pointer shaking during range conversion is minimal. It has switch protection function, common ground, floating function, and dual channel synchronous/asynchronous range control functions, making high voltage measurement safe and micro voltage measurement accurate Can conveniently test dual channel balance and amplifier gain This machine will be an ideal choice for audio engineering, college electricians, electronic laboratories, and analog signal testing
