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.

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
Page #7 of 19 ___________________________________________________________________________ M4581 – DPL4000
calculation of dew point. It is only used in the determination of ppm/ppb (parts per million/billion of water). If only dew point is displayed, the Specific Gravity value can be ignored.
Menus
The settings can be changed and functions can be selected in the menus. Follow the instructions below:
1. Open the main menu by pressing one of the
buttons.
2. Press Open within 5 seconds. Otherwise, the basic
display returns. If this happens, start from step 1 again.
3. Move in the menus using the buttons.
