Novus e
kV test
WARNING: X-rays are generated when this test is car-
ried out. PROTECT YOURSELF FROM RADIATION.
1. Connect the +probe of a DMM to test pin TP14
(kVfb) and the -probe to TP17(GND) on the Genera-
tor board.
2. Select service command exp and an exposure time
of 2000 ms (refer to section 4 Service assistant and
service functions, in this manual).
3. Protect yourself from radiation and take an expo-
sure. Check the feedback values from the DMM.
The feedback values must be within the tolerances.
Selected kV kVfb Tolerance (V)
63 2.86 ±0.1 (2.76 - 2.96)
66 3.00 ±0.1 (2.90 - 3.10)
70 3.18 ±0.1 (3.08 - 3.28)
73 3.32 ±0.1 (3.22 - 3.42)
77 3.50 ±0.1 (3.40 - 3.60)
If the values are not within the tolerances, recali-
brate the Generator board, see section 5.2 Service
Commands (the calib command).
Beam alignment test
Check the beam alignment. Refer to the Installation and
set-up manual for information on how to do this.
Ground test
Disconnect the unit from the main power supply before
carrying out this test.
For ME EQUIPMENT with an APPLIANCE INLET the
impedance between the earth pin in the APPLIANCE
INLET and any part that is PROTECTIVELY EARTHED
shall not exceed 0.1 ohm. The grounding resistance is
measured between APPLIANCE INLET ground pin and
any metal part of the unit.
The resistance MUST be <0.1 ohm.
