Indicator LEDs
Three LEDs indicate the current processing stage when using the integration measurement mode. The integration
measurement sequence is shown below.
1. Green rate LED – indicates that the measurement is in real-time. The display reading will fluctuate according to
the random nature of the radiation source.
2. Amber integrate LED – indicates that the instrument is busy. The LED will continue to flash over the duration
of the integration period.
During this period the display continues to show an averaged measurement with a one second refresh rate.
3. Red stop LED – indicates that the measurement is complete. The display no longer updates while the red LED
is flashing.
Press the Rate/Int./Stop
key again and the instrument returns to rate mode (1). The sequence is now complete.
