If disconnecting the tubing from the flow meter inlet allows air to flow out of the
tube that you can feel, the issue may be with the flow meter. Turn off the pump
and power to the DP2000. Close the lid and physically rotate the DP2000 so that
the flow meter is upside down in relation to its normal position. Verify that the
indicator ball inside freely moves when the unit is rotated. If the indicator ball
does not move, it may be frozen in the meter. See the section below about
cleaning the flow meter or contact Super Systems, Inc. at

technical support.
Cleaning the Flow Meter:
Remove the tubing from the inlet and outlets of the flow (reference Figures 20 &
21). Blow dry air, nitrogen, or argon through the flow meter to free the indicator
ball. If necessary, flow isopropyl alcohol through the meter and then flow air
through the meter to free the ball. Re-connect the sample supply tubing at the
bottom of the meter and see if there is any flow shown through the meter. If so,
reconnect the sample tubing to the top of the meter. If flow stops, the sample
tubing out of the meter may be clogged. Isolate that tubing and blow clean, dry
air through the tubing. Reconnect the tubing and check for flow.
Display appears to be locked up and never changes (not at 80°F):
Disconnect power to the unit and wait for 30 seconds. Reapply power to the unit
and verify the display. If the unit still appears to be “frozen,” please contact
Super Systems, Inc. at 513-772-0060 for more technical support.
Display reads -50°F (indicating that the sensor failed):
Please contact Super Systems, Inc. at 513-772-0060 for more technical support.
Display reads higher than normal and does not match other dew point
equipment:
If soot is allowed to collect on the dew point sensor in the instrument, it could
result in higher readings. This soot will also retain moisture than can corrode the
sensor over time. Please contact Super Systems, Inc. at 513-772-0060 for more
technical support.
RETURNING THE UNIT TO SSI –
This analyzer contains some components that may require periodic replacement
based on the amount of use that the unit experiences and the methods in which it
