Digital voltmeter
C. PROCEDURE
1. Remove trim covers to gain access to the lamp socket.
2. Verify that the specified lamp is in the socket.
3. With the light-field energized, measure the voltage across the lamp socket terminals.
4. Record the voltage measured.
5. Record the model number, serial number and calibration date of the digital voltmeter.
D. VERIFICATION OF COMPLIANCE
The voltage recorded shall be within the tolerances specified by the manufacturer.
NEMA Standard 5-15-1979
NOTE: THE AC VOLTAGE AT THE LAMP SOCKET MUST NOT BE LESS THAN 19.5
VAC RMS
XR 8-2.17 X-RAY FIELD/RECEPTOR CENTER ALIGNMENT
REQUIREMENT - Means shall be provided to align the center of the X-Ray field with
respect to the image receptor to within 2 percent of the SID (See 21 CFR 1020.31 (e)
(1) ).
A. GENERAL
1. All exposures taken during this test must have a uniform film density of approximately 1.0.
2. Actual versus indicated SID must be determined prior to performing this test.
B. EQUIPMENT
Radiographic cassette loaded with film (20 by 25 cm).
November 2005 ( 5 - 16) Linear MC150-C Collimator
C. PROCEDURE
1. Load cassette with film and place into the bucky tray.
2. Assure the X-Ray beam is perpendicular to the image receptor and centered over the bucky
tray.
