— Enclosing the beam working area with protective panels (for example, 3.0 mm stainless steel can attenuate
the beam to background levels)
Contact your Olympus representative for assistance and suggestions on interlocks and applications that limit
radiation exposure.
• Trigger issues
"Deadman trigger" mode requires the user to pull and hold down the trigger for the duration of the test.
Releasing the trigger immediately aborts the test.
3.3 Indicators and Statuses
This section explains the DELTA handheld XRF analyzer's indicators (see Figure 3-1 on page 9) and statuses.

3.3.2 X-Ray Indicator
The X-ray indicator is located on the upper rear of the instrument (see Figure 3-1 on page 9). It consists of a six-element red
LED array and provides two key functions:
X-ray indicator continuously ON (solid red LED array)
This signifies that:
• The X-ray tube is enabled.
• There is no radiation exposure to you or bystanders.
The instrument can be carried or set down safely in this condition.
X-ray indicator flashing ON (blinking red LED array)
This signifies that:
• The X-ray tube is powered to full operational level.
• The analyzer is emitting X-ray radiation through the measurement window.
In this condition, the analyzer must be pointed towards a test sample.
