WY1972P Type Dual Channel Digital High Frequency Current/Voltage MeterDetailed product description：

The WY1972P dual channel digital high-frequency current/voltage meter is a fully automatic AC current and voltage measuring instrument controlled by a CPU. It has a wide measurement response frequency range (10Hz~2MHz), and the LCD digital displays multiple sets of parameters simultaneously. It has automatic range selection for undervoltage and overvoltage indication of the measured voltage, making it easy to measure AC current and voltage simultaneously. Voltage measurement has a high input impedance (10M Ω/40pF), high measurement accuracy, and good linearity. This machine also has an input floating selection function.


Features:
◎ Automatic/manual range selection, voltage and current undervoltage and undercurrent, overvoltage and overcurrent indication.
Simultaneous measurement of AC current and voltage, with a wide measurement range (100 µ V~400V, 20 µ A-5A) and high resolution (1 µ V, 0.1 µ A).
LCD displays multiple sets of parameters simultaneously: V, dBm, and I values.
Voltage measurement automatically resets to zero, current measurement has low internal resistance (1 Ω).
