Test Consideration
For optimum performance, all procedures should comply with the following
recommendations:
– Ensure that the calibration ambient temperature is stable and between 18 °C and 28 °C.
– Ensure the ambient relative humidity is less than 80%.
– Allow at least 30 minutes of warm-up period upon power on.
– Use shielded cables only. Keep the cables that connect the test setup as short as
possible.
– In the event of a test failure, it is recommended to repeat the test to ensure that
procedural error was not made.
– The verification and adjustment procedures are based on the assumption that the
recommended test equipment is being used. Substituting with an alternative test
equipment may require modification of some procedures.
