OEC 9800 Periodic Maintenance Procedure
46
X-RAY Generator Accuracy Tests (Annual PM)
These tests measure the kVp accuracy of the system.
WARNING
:
The following steps produce X-rays. Use appropriate precautions.
Radiographic Accuracy
Set the system to
FILM
mode. Use a kVp meter. Tolerance (
±
(5% or 3 kVp) greater of the two)
Radiographic kVp Accuracy @ 50 mas
1.
Enter 50 mAs exposure. Take exposures at 60, 90 and 120 kVp and record the results on the PM form.
Radiographic kVp Accuracy @ 200 mas
1.
Enter 200 mAs exposure. Take exposures at 60, 90 and 100 kVp and record the results on the PM form.
Fluoroscopic Accuracy
Set the system to
FLUORO MANUAL
mode. Use a kVp meter for the measurements. Tolerance (
±
(5% or 3 kVp)
greater of the two)
Fluoroscopic kVp Accuracy @ 1 mA
1.
Enter 1.0 mA beam current. Take exposures at 60, 90 and 120 kVp and record the values on the PM form.
