Step 5
Calibrate the Conductron Sensor
To calibrate the Conductron sensor, see Calibrate the Module at
Atmosphere on page 35.
An atmospheric calibration is performed on the Conductron sensor at the
factory before the module is shipped. The factory calibration sets the
atmospheric calibration point to approximately 635 Torr (846 mbar,
84.6 kPa).
Because atmospheric pressure varies according to location, you should set
the atmospheric calibration point,
using N
2
or air , before putting the module
into operation. Periodic resets of the atmospheric calibration point also
improve the accuracy and repeatability of the Conductron sensor.
2.3 Eliminating Radio
Frequency Interference
The module complies with U.S. Federal Communications Commission
(FCC) limits for a Class A digital device, pursuant to Part 15 of the FCC rules.
These limits provide reasonable protection against harmful interference
when the module operates in a commercial environment.
The module generates and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions in this manual, may
cause harmful interference to radio and television communications.
However, there is no guarantee that interference will not occur in a
particular installation. If the module causes interference to radio or
television reception, which can be determined by turning the module OFF
and ON, use one of the following methods to eliminate the interference:
• Re-orient or relocate the receiving antenna.
• Increase the separation between the module and the receiver.
• Connect the module into an outlet on a circuit that is not the circuit to
which the receiver is connected.
• Consult an experienced radio or television technician for help.
