⑥ X-rays on LED and audible signal verification: While taking the exposure to verify
the x-ray beam size, verify that the x-rays on the LED illuminate and that the
audible signal is heard.
⑦ Light field size verification: With the device positioned 70cm from the wall, adjust
the shutters until they are fully open. Enable the device and measure the light field
that is displayed on the wall. It should measure approximately 26.2 cm x 26.2 cm.
⑧ Environment setting verification: Under the Environment setting screen, check that
the appropriate settings have been saved.
⑨ Charger verification: Connect the battery pack to the charger, and make sure that
the LED light signaling proper charging turns on.
8.3.3 Annual (Optional) Calibration

The iRayA6s is factory calibrated and tested prior to release and there are no
adjustment options. However, the optional checks listed below may be performed
by a qualified technician as desired.

Set up a calibrated Performance Meter (such as the Piranha554) according to
manufacturer’s specifications to detect and report the following: X-ray Tube Voltage,
Radiation Time, and Dose.
 Measurement Method : Final performance measurements are made using a
Piranha554. Exposure time is measured from the moment X-rays are detected until
they are no longer detected (which means 90% crossing setting is selected with no
timer delay). Linearity is calculated per IEC60601-2-7, 50.102.2a. Alignment of the
light field with the x-ray field is tested by IEC60601-1-3, 29.202.9. Image quality
