This meter applies micro-electronic technology to measure the power. It gets voltage sampling signals from the divider. The current divider will get the current & voltage signals from multiplier and through frequency conversion, produce a counting pulse in which the frequency is in direct ratio with the voltage current. Then the counter is driven by frequency dividing stepping motor to meter the power.
