Getting Started:

To begin taking measurements with the DPL4000:

 

• Connect a ¼” Male NPT quick-disconnect fitting (supplied) to the gas source.  This fitting will not allow the gas to flow until the mating quick-disconnect fitting has been connected.

• Attach the sensor sampling assembly to the gas source using the quick disconnect fitting at the base.

• Start the flow of gas at approximately 10 CFH.  Loosing and tightening the knob on the front of the flow meter will adjust the flow.

• Connect the small end of the Sensor Communication Cable to the port on the back of the sensor that is labeled “II”.  This will be the port without the rubber boot.

• Connect the other end of the cable to the handheld display using either one of the ports on the bottom.

• Turn on the power on the handheld display unit.

• If desired, change the environmental settings (selecting “NO” will use the default values).

• The instrument will need to go through some diagnostic tests including an automatic calibration and one or more sensor purges.  During this time, the readings on the display will either indicate all dashes, or a dew point value that does not move.  This condition will exist for between 5 and 15 minutes, depending on the dew point of the measured gas and the dew point that the sensor was exposed to prior to installation.
