Test setup and procedure
For the testing of radar SARTs, place the test box on a table or other surface that does not
reflect radio waves.
Make sure that there are no reflecting items or surfaces such as metal floors or metal walls
within a distance of at least 70 cm around the test setup.
Put a mark on the table where the SART is to be positioned during the test, which is 50 cm
from the radar antenna on the rear panel of the test box.
1) Select the Radar SARTs test mode and press OK.
2) Set number.
As you may wish to test several Radar SARTs in a row, each Radar SART can be given its own
individual set number for recognition. Default number is 1. Press OK to confirm, or press ↑ or ↓
to change to another number. Then, press OK and go to the test.
3) In the Activate SART mode, press OK and the test box will emit a 10-second audible control
burst prior to the actual test. The burst consists of tone pulses with increasing frequency.
4) During the control burst, activate the SART in test mode and keep it activated whilst placing
it on the mark on the table with the antenna part pointing down. The test box carries out the
SART test within two seconds following the control burst.
5) A double tone confirms that the test box has completed the test, and the SART can be
deactivated accordingly.
The test box will display the average frequency of the response signal transmitted by the SART
– along with a figure indicating the signal strength level. A level figure of 150 or higher should be
obtained in order to ensure a reliable test.
The test results are automatically stored in the test box memory with the facility of transferring
them to a PC at a later date.
