Warm Up
The DS360 should be turned on and allowed to warm up for at least an hour before the
performance tests are preformed. The self tests and functional tests do not require any warm up
period.
It is necessary to turn the unit off and on to reset it. As long as the unit is turned back on within a
minute, this will not effect the tests results.
Test Record
Make a copy of the DS360 Performance Test Record at the end of this section. Fill in the results
of the tests on this record. The record will allow you to determine whether the unit passes or fails
the tests and preserves a record of the tests.
If a Test Fails
Check the settings and connections of any external equipment and, if possible, verify its operation
using an oscilloscope or other piece of test equipment.
After checking the setup, repeat the test from the beginning to make sure that the test was
performed correctly.
If a test continues to fail, contact Stanford Research Systems for further instructions. Make sure
that you have the unit serial number and firmware revision number handy. Have the test record on
hand as well.
