How to manually adjust the metering frequency?

When the power button of the electromagnetic pump is pressed, the default factory setting of the metering pump frequency is 100 times or 150 times.

2. Press the down and up keys, and the measurement frequency can be adjusted freely between 0 and 150HZ. For example: Press the down key, adjust the metering frequency to 135, and press the OK key to save. (After power is cut off and the power is restarted, the data saved by the last OK key will be automatically saved.) Set the current frequency to 135HZ. It has an automatic storage function and no further Settings are required when restarting.

3. When the default factory setting of the metering frequency is 100HZ, the metering frequency can be adjusted freely from 0 to 100, and the operation method is the same as above.
