b. Source antenna should be carefully located to isolate it from
sources of reflection.
c. Source antenna should be properly polarized (vertical, if
vertical receiving antenna is used).
2. The following considerations should be taken into account when
taking measurements using a reference leak source:
a. Use a half-wave dipole when taking measurements.
b. Place dipole 10 feet from the source antenna and 10 feet from
ground, oriented with same polarization as source antenna.
CALIBRATION
When a known field is established, the vehicle may be driven
through the field and calibrated using the Compensation feature in
LEAKAGE mode. (A significant amount of compensation may be
required when using vehicle mounted antennas).
While in the LEAKAGE mode, press the
compensation. A new set of soft keys will appear. Use the
soft keys to increment and decrement the compensation value.
You can find the compensation value in the upper right-hand
portion of the screen directly below the measurement distance.
Adjust the compensation so that the leakage measurement value
displayed on the CLI-1450 matches the calibrated reference field.
Press the
soft key when you have finished.
Tip
You can quickly clear out the compensation value by pressing the
SHIFT +
keys.
