Trig button
Button for triggering.
The function of the trig button is controlled from the display device.
10 Status LED indicator
The LED (green/red) indicates the status of the Scatter Probe.
11 Rubber feet
The rubber cross on the rear of the Scatter Probe makes it safe to place the Scatter
Probe on a flat surface with the detector surface facing upwards, without slipping.
The Detector surfaces (1 and 2)
The Scatter Probe has two detector areas of 10 and 100 cm
2
respectively. The area to use for a measurement is user-selectable
from Ocean. The area to use depend on the application and what standard or regulation to follow.
Status indicator (10)
The
Scatter Probe
power on when it is connected via USB to a display unit. The status indicator turns RED when the
Scatter
Probe has power. During measurement with Ocean, the status indicator has various functions, see below.
GREEN
READY for radiation (in communication with Ocean).
Flashing GREEN
MEASURE. The Scatter Probe measures, either by auto-trig or manual trig.
RED
NOT ready for radiation.
Flashing RED
Pause
The LED bar (8)
The LED bar serves as radiation level indicator. The number of lit LEDs is proportional to the irradiation rate.
The sensitivity of the LED bar is user-selectable by setting the Alarm Level for air kerma rate, or for ambient dose equivalent rate.
The settings are made from Ocean, see Measurement settings.
The table below describes the function of the LED indicators from left to right.
1st to 7th TURQUOISE
Irradiation rate lower than Alarm Level. Each LED corresponds to 15% of the Alarm Level. The 1st
LED will light up as soon as radiation is detected.
8th Flashing ORANGE
Irradiation rate higher than Alarm Level. Range from Alarm Level to 25 mGy/h (50 mSv/h).
8th ORANGE
Irradiation rate higher than Alarm Level. Range from 25 to 50 mGy/h (50 to 100 mSv/h).
9th Flashing ORANGE
Irradiation rate higher than Alarm Level. Range from 50 to 75 mGy/h (100 mSv/h to 150 mSv/h).
9th ORANGE
Irradiation rate higher than Alarm Level. Range from 75 to 100 mGy/h (150 to 200 mSv/h).
8th and 9th Flashing RED
Detector saturation. Irradiation rate too high.
Peak Rate indication
The highest rate during the measurement is indicated on the LED bar. W hen highest rate during a measurement is indicated by
a blue LED. The indication of the highest rate will stay lit until measurement is finished.
The trig button (9)
The trig button is controlled by Ocean. The function of the button depends on measuring mode and measuring status. The
button is a pressure sensitive surface. The response of the button is indicated by the status LED (10) and a vibration.
The various functions for the trig button is described below.
