In this demo you learn about the conversion triggering modes. There are three conversion triggering modes: Auto, WaitTime and Manual.

In the sample script we provide, a ticks counter is incremented each 30 ms after the document was loaded. When the ticks count reached 100 in about 3 seconds the startConversion() is called.

When the triggering mode is Manual the call to startConversion() will trigger the conversion.
When the triggering mode is WaitTime a wait time of 5 seconds is sufficient to allow the ticks count reach 100.
When the triggering mode is Auto the conversion will start before the counter reached 100.
