Performing a Low Flow Setpoint Adjustment

If your instrument repeatedly goes into low flow alarm and you have tried all

of the recommendations in the Troubleshooting section, you may need to

perform a low flow setpoint adjustment.

1. Use the AIRS or (SHIFT)T buttons to display the FLOW ADJ menu

item. Press and release the POWER ENTER button. The pump will turn

off and the screen will display values that reflect the pump’s current draw.

2. Use the AIRS or (SHIFT)T buttons to get a reading of approximately

1500 on the bottom value. When you have adjusted the value as close as

you can, press and release the POWER ENTER button.

3. The pump will turn on and two new values will be displayed. The top will

be a reference value and the bottom will reflect the pump’s current draw.

Connect a flow meter to the inlet of the instrument and adjust it to 0.5

SCFH ± 0.1 SCFH. This will be the low flow setpoint. You do not need to

adjust anything at the instrument. Once the low flow setpoint is set, press

and release the POWER ENTER button.

4. You will return to the FLOW ADJ menu item in Maintenance Mode.

Exiting Maintenance Mode

1. Use the AIRS or (SHIFT)T buttons to display the START menu item.

Press and release the POWER ENTER button.

2. The unit will exit Maintenance Mode and begin its start up sequence.
