High-speed imaging meter testing program

Via RS485 Settings "preset test time pulse number" is 0, the preset test volume to zero. Switching signal from the high level to low gear start counting immediately, high-speed timing (accuracy 0.01ms) and real-time pulse output. When switching the signal level from the low to high gear to stop immediately count, high-speed counting and pulse output. It can be read via RS485 cumulative number of gears and accumulated high-speed timing pulses
