1. Open the sample inlet valve, see A .<br />
• Positioning valve with pointed end facing up for open position.<br />
2. Open the bypass/needle valve by turning counterclockwise, see B .<br />
• Check for appropriate sample flow.<br />
• Adjust pressure regulator if required. See step 3.<br />
3. Adjust the knob on the pressure regulator, see C , so the ball in<br />
the flow meter indicates the correct flow rate reading, see D .<br />
The flow rate should be adjusted to 40 mL/min.<br />
• Pull out the knob to unlock the setting and allow adjustment of the<br />
flow rate.<br />
• Turn the knob clockwise to increase the flow rate.<br />
• Turn the knob counterclockwise to decrease the flow rate.<br />
• Push in the knob to lock the setting.<br />
4. Push in the diverter valve on the flow cell.<br />
• Flow cell will begin to fill.<br />
5. Flush the flow cell for 10 to 60 minutes. The sample will drain from<br />
the siphon tube into the siphon drain to the waste.<br />
6. Begin a DKA calibration. Refer to Chapter IV, Before Performing<br />
