3. Connect Digital Voltmeter (Fluke 8000A) to read the ac lamp voltage at the collimator lamp socket
terminals.
4. - Depress the FIELD LIGHT Button and read Lamp Voltage.
5. Compare Lamp Voltage to no-load battery voltage as listed in the table below. If necessary, extrapolate
between values. The lamp voltage must be equal or greater than the values given, however too high
a lamp voltage will reduce lamp life.
No Load Minimum Lamp Voltage (VAC)

128 222 243
126 22.0 24.1
124 21.7 23.8
122 21.4 23.5
120 21.1 23.1
118 20.7 22.7
116 20.3 22.3
114 19.9 21.9
112 19.5 21.5
110 19.0 21.0
6. The secondary of 8T1 is factory connected to the Blue Tap. A shift to an adjacent 8T1 tap will
change lamp voltage by approximately 0.5 v rms. If necessary, select the lowest voltage tap of 871
that provides at least the minimum voltage listed in the Table above.

7. Replace nameplate and knobs after verifying that the collimator lamp is operating in the proper
voltage range.
8. Record Collimator Lamp Voltage and battery voltage on F-3382, Test 27-33, Set F.
5-6 Coilimator Beam Alignment Tests
To meet HEW requirements:
a. The misalignment of the edges of the light field with the respective edges of the x-ray field
along either the length or width shall not exceed 2% of SID when the field is perpendicular
to the x-ray beam.
