DP2000 Portable Dew Point Analyzer Operations Manual
To prevent the possibility of moisture damaging the instrument, be sure that the
measured dew point is below ambient levels before it is stored. If necessary, dry
compressed air, nitrogen, or argon can be used to purge the instrument after
use.
If the DP2000 still reads 80°F (27°C) after completing the procedure to dry out
moisture, please contact Super Systems, Inc. at

support as the sensor is likely damaged and will need to be replaced.
No visible flow is shown in the flow meter:
Sampling Pump Does Not Function When Energized:
Verify that the unit is powered up and the pump is turned on. Listen for the
sound of the pump (normally, the pump is loud enough to hear when it is
energized). If the pump does not sound like it is energizing, please contact Super
Systems, Inc. at
for more technical support. Otherwise, if the pump

is running, see below for additional troubleshooting tips.
Sampling Pump Does Function When Energized:
Option 2
Follow the
instructions in the Troubleshooting section labeled, Drying
out the Model DP2000:, to verify that the internal tubing is clean and free of any
moisture, dirt, and debris.
Verify that the pump seals are still good. Open the flow control valve on the flow
meter (reference Figure 3). To do this, turn the black knob on the bottom of the
flow meter counter-clockwise (or to the left) as much as possible. With the
sampling pump running, open the face pate (reference Figures 8 & 9) and verify
that the tubing connected to the outlet of the sampling pump is actually
connected and hasn't come loose (reference Figure 20). Verify that the tubing is
also still connected to the bottom of the flow meter (also reference Figure 20).
Disconnect the tubing from the sampling pump inlet (reference Figure 19) and
flow meter outlet (reference Figure 21).
Check the flow through the meter to see if it is at least 1.5 CFH. If not,
disconnect the tubing to the bottom of the meter and physically feel if there is
any air coming out of the pump. You can do this by putting the tubing up to your
lips or tongue to feel air flow. If you can't feel any air flow, disconnect the other
end of the tubing from the sampling pump outlet and blow compressed air
through the tubing to verify that there is no blockage in the tubing. Reconnect
the tubing. If this does not help, the seals have probably failed and the pump
needs to be replaced. Please contact Super Systems, Inc. at
