SETTING: TRIG MODE

The trig mode setting affects both how a measurement is triggered and which parameters are displayed.

AUTO

When in auto trig mode, start of measurement is triggered by radiation, with trig level (N80) 20 μSv/h or 10 μGy/h

 (1.2 mR/h). The sensor is in this mode useful as a sensitive dose rate meter, placed in the primary X-ray field.

Parameter displayed are:

accumulated dose,
time,
instantaneous dose rate (final reading: average dose rate),
mean energy.

MANUAL

In manual trig mode, you can start and stop the measurement from the base unit. This mode is suitable for

 measuring leakage or scattered radiation from X-ray equipment and γ-emitting isotopes.

Parameters displayed are:

accumulated dose,
time,
instantaneous dose rate (final reading: peak dose rate),
mean energy.
