system has not improved the experience, connect a Multi-sensor or Dose Diode and locate it somewhere

in the radiation beam so that it can serve as a trigger source.

High – Select if Std causes false triggering.

Note: If you have a strong, noise free signal, selecting High will minimize the time the system measures

a background zero in between measurements allowing you to make continuous measurements rapidly. A

new zero will be recalculated every 5 minutes.

Free - Disables the trigger. The Free mode provides a manual trigger with the Play/Pause button. A

measurement will begin after you select Free and the sensor(s) are initialized. The measurement will

continue until you select Disconnect. This can be useful to check for grounding issues since you can

record and document the noise levels.

HINT: Use Free for very low dose rate measurements with the 180CC or 1800CC ion chambers.

or in WiFi mode:

This function is only available when an ion chamber is connected and the system has been started and is

ready to measure. Selecting IC ON will give a warning about grounding and provides frequency corrected

IC waveforms. IC triggering with Wave mode set to Off will work with all settings (Low, Std & High) because

it suppresses noise. This of course makes the waveforms very distorted, but much lower IC dose and dose

rates can be measured.

This setting becomes available when an Ion Chamber or a Dose Diode is connected and is the trigger

source. There are occasions when using an IC or DD, that the automatic dynamic stop trigger ends an

exposure inappropriately. This may happen with long slowly changing or undulating waveforms such as

CT scans or fluoro exposures. One method to avoid this is to use a second sensor as a trigger (e.g. Dose

Diode) or to use Free Run as a trigger. NOTE: The default value for Dynamic Stop trigger is On. Important:

Only change the Dynamic Stop Trigger to Off if you experience a faulty ending triggers with ion chambers

or dose diodes.

Not available in WiFi mode
