Verification Kit Part Number 7000A846

Introduction

Connecting a mismatch of a known value and measuring it with the Antenna Tes­ter provides a test to determine the degree of measurement accuracy.

Measurement accuracy is specified to be ± 0.040 of Rho (p), where:

VSWR 1–

ρ

-------------------------=
VSWR 1+

Because of the manufacturing tolerance, each mismatch is analyzed across the
frequency band of the Antenna Tester. Rho data is recorded so that future com­parisons can be made without regard to the manufacturing tolerance.

This verification kit is used to verify Antenna Tester performance. It is intended
for use with the AT-800 Antenna Tester. These instructions were written with the
understanding that the operator is familiarwith the operation of the Antenna Tes­ter. Refer to the Antenna Tester Operator Manualfor more information.

6. Press the SINGLE FREQ key.

7. Press the UNITS key.

8. Press the RHO key.

9. Press the FREQ MHz key.

10. Using the numeric keys, enter 806.

11. Press the ENTER key.

12. Compare the resultant value to the minimum and maximum values listed for
806MHz.

13. Repeat for 833MHz and 960MHz. To enter another frequency repeatedly press
the SELECT key until the cursor is blinking on the frequency, then use the
numeric keys to enter the desired frequency.

14. If any value is outside the listed minimum and maximum acceptable values
see the Calibration section on page 3.

Calibration

For maximum performance and accuracy, the Antenna Tester should be calirated
once every 12 months or if the verification test indicates the accuracy is not within
the specified range. Return the unit to the Bird Electronic authorized service
center listed below.

Limited Warranty

All products manufactured by Seller are warranted to be free from
defects in material and workmanship for a period of one (1) year,
unless otherwise specified, from date of shipment and to conform to
applicable specifications, drawings, blueprints and/or samples. Seller’s
sole obligation under these warranties shall be to issue credit, repair
or replace any item or part thereof which is proved to be other than as
warranted; no allowance shall be made for any labor charges of Buyer
for replacement of parts, adjustment or repairs, or any other work,
unless such charges are authorized in advance by Seller.

If Seller’s products are claimed to be defective in material or work­manship or not to conform to specifications, drawings, blueprints and/
or samples, Seller shall, upon prompt notice thereof, either examine
the products where they are located or issue shipping instructions for
return to Seller (transportation-charges prepaid by Buyer). In the
event any of our products are proved to be other than as warranted,
transportation costs (cheapest way) to and from Seller’s plant, will be
borne by Seller and reimbursement or credit will be made for amounts
so expended by Buyer. Every such claim for breach of these warranties
shall be deemed to be waived by Buyer unless made in writing within
ten (10) days from the date of discovery of the defect.

The above warranties shall not extend to any products or parts thereof
which have been subjected to any misuse or neglect, damaged by acci­dent, rendered defective by reason of improper installation or by the
performance of repairs or alterations outside of our plant, and shall
not apply to any goods or parts thereof furnished by Buyer or acquired
from others at Buyer’s request and/or to Buyer’s specifications. Rou­tine (regularly required) calibration is not covered under this limited
warranty. In addition, Seller’s warranties do not extend to the failure
of tubes, transistors, fuses and batteries, or to other equipment and
parts manufactured by others except to the extent of the original man­ufacturer’s warranty to Seller.

The obligations under the foregoing warranties are limited to the precise
terms thereof. These warranties provide exclusive remedies, expressly in
lieu of all other remedies including claims for special or consequential
