SETTING: STOP DELAY

The stop delay setting defines for how long the instrument will wait for more radiation to include in the same

 measurement.

Use a longer stop delay when measuring on a pulsed fluoroscopy system or to get a prepulse recorded into the

 same measurement as the following ordinary exposure.

Stop delay setting longer than the time between pulses (t>T), will result in one long measurement. Note that you

 have to wait as long as the stop delay setting (t) after the last exposure before the measurement ends and values

 will be displayed.

Stop delay setting shorter than the time between pulses (t<T), will result in many short measurements (one for each

 pulse).
