5. Calculate KVP (MIN) and KVP (MAX) for 50, KVP (MIN) = KVP (measured) x 110
80 and 110 KVP based on measured KVP and Bat. Volt (Measured)
battery voltage.
KVP = KVP (measured) x 120
MAX

m Bat. Volt (Measured)
6. Record data on F3382, Test 19. Refer to III. 4-11-40. Calculate KVP deviation. KVP-(MIN) and KVP
(MAX) must be within (+)10 KVP +5%) (-(5 KVP +5%) of each selected value. If KVP is too low,
disconnect tap 4 of 1T1 from 2TB1-P1L and replace it with tap 3 of 1T1. Repeat accuracy test.
7. Turn keyed switch and circuit breaker OFF. Remove H.V. Divider and scope. Connect 10 ft. H.V.
cables to tube unit using standard procedure. Replace the cable tie-wrap on the cathode H.V. cable.
Dc not disconnect tube current test meter.
.. 8. Turn circuit breaker and keyed switch ON. Make an exposure at 80 KVP, 200 MAS. Readjust 3A2R34,
| if required for MA value of Step 3. Readjustment of 3A2R30 may be required to compensate for re-
moval of H. V. Divider and 5 foot cables.
9. Turn keyed switch and circuit breaker OFF. Remove the tube current test meters and reinstall the MA
(+; to MA (-) jumper. Do not disconnect the battery voltage DVM.
10. Optional MAS test. (Not required for field installation) may be performed by inserted MAS meter
(FLUKE 8000A/W MAS option) into the MA + MA - terminals of panel 3. With battery voltage in
the green band, record 10 consecutive exposures. Compare dial selection of MAS to reading on cal-
ibrated MAS meter. Readings should be within accuracies as stated in Chapter 4, Section 1.
