båÖäáëÜ
4. DANGER! After switching off the unit, wait at least 4 minutes (LED
V500 on the DX6 must no longer be on) before removing jumper H
from the DX6 board.
Remove the jumper (H) from connector X302 on the DX6 board.
5. DANGER! Only use fully insulated measuring wires.
Connect the digital multimeter with the measuring wires to test points
MA- (X5-) and MA+ (X4+) at connector X302 on the DX6 board.
6. On the multimeter, select the current measuring range 20mA DC.
7. NOTICE! If the lid of the tube assembly cover is not attached, the ring
circulation is impeded and the unit can be damaged.
Temporarily install the lid of the tube assembly cover (E) on the unit
using the screw (D).
8. DANGER! Do not touch any live components!
Set the main switch (A) to I (see also Operating Instructions).
9. Wait for approx. 1 minute.
10. Press the R key.

The unit moves to its starting position.
Performing measurements XG 3D
Performing measurements 1. Select the P1 program (see Operating Instructions).
2. Set the highest kV/mA level, 66kV/8mA (see Operating Instructions).
3. Make ready for exposure in SIDEXIS (see Operating Instructions).
4. CAUTION! Activating the release button triggers X-rays.
Start the exposure by pressing the release button. Hold down the
release button until image acquisition is completed and the acoustic
signal that indicates the end of the exposure can be heard.
Evaluating measurements XG 3D
Analyzing measurements ➢ Read the voltage value on the display of the multimeter.

The tube current must be 8mA ± 1.6mA.

If the measured value does
not
fall within the permissible
tolerance, replace the tube assembly (see Service Manual).

If the measured value falls within the permissible tolerance,
conclude the measurement.
Concluding the measurement 1. Switch the unit on via switch (A) (see also Operating Instructions).
E
D
IMPORTANT
1 mA corresponds to a tube current of 1 mA. The permissible tolerance
is ± 20 %.
