Calibration

It is suggested that this device should be calibrated on a routine basis, such as once
per year or as prescribed by the user’s quality system requirements.

Sensor Technology:

The dew point measurement is based on a capacitive thin film polymer. Water
molecules in the surrounding air or gas diffuse into the polymer layer through the
permeable upper electrode, which changes the capacitance of the sensor. Changes
in capacitance can be directly correlated to the quantity of water molecules in the
gas.

Special Features:

The dew point sensor in the DPL4000 performs two functions that provide increased
accuracy and response time.

 Automatic Calibration – The sensor warms itself and performs an offset (zero

point) correction. This is performed automatically at start up and after every 45
minutes of continuous use.

 Sensor Purge – This function evaporates all excess moisture molecules from the

sensor to significantly increase the response time when the sensor goes from a
wet condition to a dry condition. This is performed automatically at startup and
after every 24 hours of continuous use. A Sensor Purge will also be initiated
automatically when the sensor detects a large wet-to-dry environmental change.

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.

Installing and Removing the Battery Pack

The DPL4000 is supplied with a rechargeable battery pack. It is

also possible to power the instrument using four (4) “AA” 1.5V

alkaline batteries. To use the alkaline batteries, you will need
to install the supplied metal contact plate at the base of the
battery housing.

1. Unscrew the back plate of the indicator.

2. Remove the old batteries. If a rechargeable battery is
installed, remove the black connector by gently pulling up
on the wires.

Figure 1 Installing the Battery Pack

3. Connect the black connector of the new rechargeable
battery pack. Make sure the red and black wires are on
the upper edge of the connector. Do not push the
connector with any conducting material. If using alkaline
batteries, the metal contact plate will need to be inserted
if it is not already present.

4. Close the back plate, and tighten the screw.

5. Charge the battery before use.

Charging the Battery Pack

1. Plug the charger into the top of the indicator (located
under the rubber cap).

2. Connect the charger to a wall socket. A dynamic battery
symbol will be visible in the top left corner of the display.

3. When the battery symbol does not change, the battery
pack is fully charged.

4. Disconnect the charger.

The duration of recharging is typically 4 hours.

Pressure (P) - Preset to Atmospheric Pressure at time of

manufacture

Specific Gravity (G) – Preset for Nitrogen

NOTE: For most applications, the default values for each of

these settings will be appropriate. The variations in
Atmospheric Pressure will have negligible impact on the
resulting dew point. The Specific Gravity is not used in the
