In this step, you must inject 0.5mL into the chamber.
Use the 1mL syringe and inject the 0.5mL volume fast enough, but without exceeding ±5volts on the chart. This
may take some practice and you can repeat it as many times as you want. Before you deliver the volume, make
sure the entire chart is at zero. When you feel you have a good injection, click Next while the entire injection is still
on the chart. If part of the injection runs off the chart, then you must repeat it. After you click Next, and
FinePointe has checked your delivery is good, it will freeze the injection for you to accept.
Note: The polarity of the voltage signal may be inverted from what you see here. That is due to
the orientation of the transducer. If you choose, you can leave it inverted. The calibration
process will correct it. Or you can reverse the way the transducer is plugged in and retry this
