To set the flow rate on the E-RPISU Radon Progeny Monitor, follow these steps:
1. When the unit is powered up and the "READY" message is displayed on the LCD screen, press the red stop button.
2. The elapsed time will be displayed for a few moments. While the elapsed time is displayed, press the start button.
3. This will start the pump under control of the potentiometer, and allow you to adjust the flow rate by turning the blue flow adjustment xxxx . Turning the xxxx clockwise will increase the flow rate, while turning it counterclockwise will decrease the flow rate.
4. Once you have set the desired flow rate, press the red stop button to calibrate the pump to this new value. The LCD screen will display "WAIT" for a few moments while the new flow rate is being internally set.
5. After the new flow rate has been calibrated, the E-RPISU Radon Progeny Monitor will return to the "READY" state.
It is recommended by Rad Elec to set a flow rate of approximately 0.8 liters per minute.
