D.4 Checking the Proper Function of the System

To ensure your radEAGLE is working properly, we will supply a short checklist for successful

operation.

1. Check the status of the battery failure LED

a) After some time, the booting screen of the radEAGLE should appear.

• If the screen does not appear, check if the display has backlight. If not, there

might be a problem with the battery. Power the instrument with external

power and check whether the problem persists.

• If the instrument boots with power cable connected, check the status of

the battery switch in the rear battery chamber of the instrument.

b) Is the orange battery fault LED on?

• If yes, there might be charging problem or some other problem with the

batteries. If it is running, turn oﬀ the instrument, and try charging the bat-

teries.

2. System boot-up and welcome screen

a) Self-checking routines run in the background of the boot process. If a self-check

fails, a corresponding error message will appear on the device and give you fur-

ther advice.

b) Once started, the system should welcome you in dose rate mode. If no source

is around, the ambient dose rate is expected to be between 0.01 µSv/h and

0.08 µSv/h.

c) The count rate in cps should be greater than 0. There are always natural radia-

tion counts.

d) If you have a neutron detector, the neutron cps should be close to 0.00 cps.

Sometimes values of about 0.05 might occur. If you observe a neutron count

rate of 0.5 cps or greater, it is likely that a neutron source is nearby.

e) If the battery was charged, the battery status bar should indicate fully charged

status

f) If the bar shows a low battery, this might point towards a problem with the bat-

teries. Try charging the battery again.

3. Speciﬁc checks in spectrum mode

a) Enter spectrum mode. Without a source, start a spectrum acquisition and ob-

serve the area around 1460 keV. After a few minutes, the natural potassium

peak should appear at 1460 keV. You can use this peak to verify the correct po-

sitioning of the instrument even if no cesium calibration source is available. After

fresh startup, the instrument should have at least a precision of around ±0.5 %

of the line energy or a maximum deviation of ±7 keV around the 1460 keV line.
