Necessary Equipment

The performance tests described in this section are designed to verify
with a high degree of confidence that the unit is performing correctly.
The results of each test may be recorded on the test sheet at the end of
this section.
If you need to contact Stanford Research Systems, please have the
serial number of your unit available. The 5-digit serial number is printed
on a label affixed to the rear panel. The serial number is also displayed
when the unit is powered on.
The firmware revision code is shown after the serial number when the
unit is powered on.
Throughout this section, it will be necessary to preset the lock-in into a
known default state. To do this, turn the power off. Turn the power back
on while holding down the [Setup] key. The unit will perform power up
tests and then assume the default settings. Each test generally starts
with a preset. This procedure will be referred to as {PRESET}.
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.
Make a copy of the SR810 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, you should check the settings and connections of any
external equipment and, if possible, 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 performed 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.
The following equipment is necessary to complete the performance
tests. The suggested equipment or its equivalent should be used.
