10.1 Remove the cap of the 11.3% salt solution and install the sensor gland
(with the sensor) into the salt solution. To increase the life of the calibration
salts, an effort should be made to minimize the amount of time that the salt
solution is exposed to the ambient air.
10.2 Turn the unit off.
11.0 Allow the sensor to reach equilibrium with the calibration salt.
11.1 With the power to the unit still turned off, leave the sensor in the
calibration salt for a minimum of 24 hours. It is acceptable to leave the
sensor in the salt solution for a longer period of time, even a few days, if
desired.
12.0 Begin the 11.3% (Zero) calibration process
12.1 After leaving the sensor in the salt for at least twenty-four (24) hours, turn
the unit on. The reading on the display is not important at this point.
12.2 Simultaneously press the “11.3%” and “Calibration” buttons on the
microprocessor board.
13.0 Verify the 11.3% (Zero) calibration
13.1 Do not be concerned if the unit does not display 11.3, since it is not
supposed to match the value of the calibration salt.
13.2 Use the “Sensor Temp” switch on the faceplate of the unit to determine
and record the sensor temperature.
13.3 Look up this temperature on the “Theoretical Dew Point Values for
Calibration Verification” chart located in the back of this manual. Appendix
“A” will show the temperature values in Fahrenheit, and Appendix B will
show the temperature values in Celsius.
13.4 Next to the appropriate temperature, note the number in the corresponding
column titled “11.3%”. This should match with the dew point that is shown
on the display of the DP2000.
