Overview
The 210-2002 is a Vaporstat™ wall-mounted dewpoint sensor. The sensor is designed for measuring indoor or outside dewpoint or absolute humidity level.
Sensor Wiring
1. For wiring the dewpoint sensor to a CPC input board, use Belden #8761 shielded two­conductor cable or equivalent.
2. Connect the BLACK and WHITE wires to the screw terminals on the sensor’s connector as shown in Ground and WHITE to 0-5V Output). Clip the SHIELD wire.
Figure 1 - Sensor and Input Board Wiring
3. Connect the SHIELD and BLACK wires to the 0V terminal of the input board. Connect the WHITE wire to the SIG terminal of the input board.
4. Connect 24VAC (a separate 120VAC/24VAC transformer must be used P/N 640-0039) to the power terminal on the dewpoint sensor back plate using the BLACK and WHITE wires. (This 24VAC transformer must only be used to power this dewpoint sensor. Do not use
Figure 1
(connect BLACK to Signal
this transformer to power additional devices.)
5. Locate the input dip switch for the sensor point, and set to the OFF position (LEFT for MultiFlex, DOWN for 16AI). Refer to the input board’s user manual for locations of the input dip switches.
Controller Setup
DO NOT set this sensor up with a sensor type
of “Dewpoint”; that setting is only for CPC Dewpoint Probes (P/N 203-1902). This dewpoint sensor MUST be set up as a sensor type.

Set Up Zero Calibration
The Zero Calibration mode allows the user to calibrate the sensor to a verified zero concentration of water vapor. For best results, allow the sensor to warm up for at least 10 minutes.
For zero calibration, all tubing should be connected between the gas bottle and the sensor inlet flow port. Before initiating calibration using the sensor keypad, the gas should be flowed to the sensor at a rate of 80­100 cc\minute for a period of five minutes.
Observe the following steps to set up Zero Calibration mode.
1. Attach the short hose to the bottom port on
the flowmeter.
2. Attach the long hose to the top port on the
flowmeter.
3. To ensure the meter is kept in the vertical
position, secure the flowmeter to the side of the gas bottle using the supplied tie wrap.
4. Remove the protective cap from the
nitrogen bottle and attach the gas regulator.
5. Attach the open end of the bottom hose
(located on the flowmeter) to the gas regulator. Slide the hose far enough on the gas port to ensure a secure, airtight connection.
6. Insert the male luer fitting (located on the
longer hose) into the calibration port, located on the bottom of the dewpoint sensor.
7. Verify that all components are installed
correctly and initiate the calibration process by turning the knob on the regulator. Turn the knob until the indicator reaches 7 psi.
8. Turn the flowmeter knob until the floater
reaches 80-100 cc/minute.
9. Allow the gas to flow for at least 5 minutes
before proceeding.

10. Press the Clear and Enter buttons together
and hold for five seconds. The word CAL will appear in the topline of the LCD display:
11. Use the arrow buttons to toggle to the Zero
Calibration mode.
NOTE: Prior to pressing the Enter button, the zero
gas should be flowing to the dewpoint sensor for atleast five minutes.
12. When ZERO is displayed, press the Enter
button to initiate the calibration process.
13. Once the Enter button is pressed, the
calibration process will take five to seven minutes during which time the green LED below the display will flash. Once calibration is completed, the sensor will revert to its normal display mode.
Calibration Layout
Refer to the calibration topic of the manufacturer’s manual for the sensor’s zero calibration layout. Contact your CPC sales representative for calibration kit (P/N 210-2005) purchasing information.
