4. Disconnect the coaxial cable and re-install the sensor in its normal position. Reconnect the
coaxial cable.
This procedure re-confirms that the sensor is correctly calibrated to the hygrometer.
We recommend that verification of the overall linearity of calibration of the system should be
carried out on a 12 monthly basis.
4.2 Programmed
Settings
The
dew
TEC DS2000 has two setting modes that modify the hygrometers’ operation. The
modes and parameters are shown in the following table:
MODE PARAMETER
Program Mode
Calibration Data, Decimal Point Position,
Linear Output scaling, Offset, Filter,
Communications address and baud rate,
Display Colour, Lock, Help on/off
Configuration Mode
Alarm Mode, Alarm Direction, Linear
Output type, Totaliser
Enter the mode that you require as described in this section to change a parameter.
NOTE
: Many of the parameters are factory set during manufacture, test and calibration. Do
not change any of these settings as your hygrometer may give erroneous readings without you
knowing.
