Performance Tests

Warm Up

The lock-in should be turned on and allowed to warm up for at least an hour before any tests are performed. The self test does not require any warm up period.

It is necessary to turn the unit off and on to preset it. As long as the unit is powered on immediately, this will not affect the test results.

The Test Record

Make a copy of the SR850 Performance Test Record at the end of this section. Fill in the results of the tests on this record. This record will allow you to determine whether the tests pass or fail and also to preserve a record of the tests.

If A Test Fails

If a test fails, you should check the settings and connections of any external equipment and, if pos- sible, verify its operation using a DVM, scope or some other piece of test equipment.

After checking the setup, repeat the test from the beginning to make sure that the test was per- formed correctly.

If the test continues to fail, contact Stanford Research Systems for further instructions. Make sure that you have the unit's serial number and firmware revision code handy. Have the test record on hand as well.
