Scheduling the tests

The test scheduler lets you set the date and time at which the next impedance test will be executed, and whether it is to be repeated at regular intervals thereafter. It also lets you set the schedule independently for each amplifier channel, together with the frequency to be used and the tolerance to be applied.

An impedance measurement outside the prescribed tolerance will be classified as a Test

Failure, be recorded in the amplifier log and/ or generate an email alert (if set up in Event

Logging).

In systems with multiple amplifiers, each amplifier may run its own set of tests simultaneously if wished. However, it is not possible to run tests on more than one channel within each amplifier simultaneously, so test times for the channels in any one amplifier should be carefully staggered.

To add a test to the scheduler, select a channel from the drop-down list under Scheduled

Tests, select the frequency to be used (see remarks above), and select a tolerance; 30% is recommended initially. Click the calendar symbol to open the test scheduling calendar window.

If the test is to be repeated on a regular basis, select the repetition rate using the lower set of date/time spin boxes. Note that test intervals can be set in increments of one minute up to several years.

When all the scheduling data has been entered, click Apply to close the window. The date and time at which this particular test will be next run is displayed. To add the test item to the schedule, click the ‘ +’ button at the end of the test item line.

Further tests may be added using the same procedure. Tests may be added with any or all of the same settings, or different settings may be used. A test item may be deleted from the schedule by clicking its ‘ x’ button. When the test schedule for the amplifier is complete, the process should be repeated for the other amplifiers comprising the system.

Select the date on which the next test is to be run by clicking on it. The months can be scrolled through with the ‘ |<’ and ‘>|’ buttons at the top. Next select the time at which the test is to be run using the Hours and

Minutes spin boxes.
