RK9800N series digital power meter

The RK9800N series digital power meter is used to measure common parameters of alternating current, such as voltage, current, power, power factor, power (energy), and frequency.
The RK9800N series products are upgraded versions of the RK9800 series. Compared to the RK9800 series, the new products have the following advantages:
Add two products: high current and low current.
Add power (energy) display function.
The entire series can be equipped with optional communication functions.
The adjustment process for current and power exceeding limits is more intuitive and easier to operate.
The alarm functions for current and power exceeding the upper limit and lower limit can be set to enable or disable separately.
The time for over limit alarm can be adjusted.
