SECTION VI
CALIBRATION
6-1 GENERAL
The Model HI-3510 should be calibrated at 12 month
intervals. To do so requires the use of highly specialized
test equipment and facilities, such as a radio-frequency
anechoic chamber and TEM cells, wherein fields of
known power density can be accurately established. It
should also be noted that to establish the required power
densities will require CW sources of 10W or greater
together with accurately calibrated test antennas and
power monitoring equipment. If facilities of this type are
not available, the unit should be returned to Holaday
Industries or to another qualified calibration facility for
this service.
6-2 CALIBRATION PROCEDURE
6-2-1 Set the alarm warning level to 0.5 mW/cm 2 as
described in paragraph 3-4-2.
6-2-2 Disable the latch function as described in
paragraph 3-4-4.
6-2-3 Following the procedures described below,
position the unit in a 50 - 500 MHZ TEM cell and
in a 900 MHZ to 2.5 Ghz anechoic chamber.
The preferred orientation of the E-field is parallel
to the vertical axis of the unit.
6-2-4 At each test frequency, raise the power density
level at the unit until an alarm is indicated.
Record this power density level on the test data
sheet in mW/cm 2 .
