To avoid electrical shock from components under voltage, also be
aware that:
The capacitors of the capacitor bank can be electrically charged
even when the system is switched off and the power cable is disconnected!
Individual capacitors of the capacitor bank may have been disconnected from the discharging circuit, erroneously or as a result of
failure, and can still be electrically charged!
Disconnect the battery blocks in the XP Digital prior to maintenance and service work!
Carelessness can result in death or serious bodily injury.
¹ Make sure that no parts or tools fall into the unit;
¹ Do not touch potentially dangerous
components(Fig.2/p.11)
¹ If loose parts must be removed from the unit, use only
insulated tools;
¹ Protect the work area so that no other persons are able
touch the unit while the covers are open or removed!
• Switch the unit off before servicing or maintenance. Always disconnect the power plug
first.
• Make sure that the main switch is switched off.
• The capacitor bank discharges to < 40 V in approx. 15 minutes.
¹ The safety covers can be removed after this period has elapsed.
• Prior to performing any work, it must be verified that areas with dangerous voltage are
voltage-free (Fig.2/p.11).

Requirement:
• The coefficient of variation for the radiation dose for any combination of exposure pa-
rameters does not exceed 0.045. This requires operation at the line voltage compliant
with Siemens specifications.
X
NOTE
Required measuring instrument:
- Dosimeter
Procedure:
In the following test, 10 sequential exposures are taken within one
hour.
The exposure parameters should be temporarily set to different
values following each measurement.
• After switching the system on, wait until its temperature has stabilized. The unit is ready
for these measurements after 15 minutes.
• Release the number of exposures with the specified exposure data:
- 85 kV, 1.0 mAs, 10 exposures.
• Measure the dose for each exposure.
• Reset the display prior to each new measurement.
Calculations: Coefficient of variation C
• For a series of 10 dose measurements, coefficient of variation C is determined using
the following formula:
Fig. 21:
s = Standard deviation resulting from the measurements
