§4. Using the Light Integrator

The light integrator front panel has a TFT display and four function buttons: 

          ⊙  Calibrate

↑  Increase Exposure
↓  Decrease Exposure
⊛  Start/Stop Exposure

The usage of these buttons is explained in the following sections.

Selecting a Light Source

Light source selection is automatic, based upon the attached sensors. The attached sensor type is shown on the first line of the display.

Setting the Exposure

The currently selected exposure value is shown on the second line of the display. The exposure value can be set to anything between 1.0 and 30,000, which, for a calibrated system, represents an exposure time from about 1 second to 8 hours.

  • To increase the exposure value, press the INCREASE button. Long presses will increase the exposure value faster
  • To decrease the exposure value, press the DECREASE button. Long presses will decrease the exposure value faster

[Firmware 1.3.47] When the exposure value is changed, the light integrator will store it and use the value as the default when next switched on.

[Firmware 1.3.48 or later] After a new exposure value has been used, the light integrator will store it and use the value as the default when next switched on.

Starting the Exposure

Once a suitable exposure value has been chosen:

  1. Press and release the START/STOP button to begin the exposure
  2. If using the power controller, then the mains electricity supply to the light source will automatically be switched on. If not using the power controller, then do this manually
  3. The light integrator display will show the remaining exposure, which counts downwards to zero
  4. Once the light integrator detects light then it will also start a timer. The clock is shown on the third line of the display. This counts upwards
  5. If a temperature sensor is attached, then the temperature readings are shown on the fourth line of the display
  6. Once the exposure value reaches zero, the light integrator will beep and stop taking measurements
  7. If using the power controller, then the mains electricity supply to the light source will automatically be switched off. If not using the power controller, then do this manually
  8. The light integrator will display the total exposure (i.e. the exposure value) along with the total exposure time

The system is immediately ready for the next exposure. Pressing the START/STOP button will begin a new exposure. The INCREASE and DECREASE buttons will adjust the exposure value as normal.

Pausing the Exposure

To pause the exposure, press and release the START/STOP button.

If using the power controller, then the mains electricity supply to the light source will automatically be switched off. If not using the power controller, then do this manually.

Press and release the START/STOP button to restart the exposure. The timer will continue once light is detected.

If using the power controller, then the mains electricity supply to the light source will automatically be switched on. If not using the power controller, then do this manually.

Cancelling the Exposure

To cancel the exposure, first pause it then press the CALIBRATE button.

If using the power controller, then the mains electricity supply to the light source will automatically be switched off. If not using the power controller, then do this manually.
