Performing and analyzing a measurement
1. Set the highest kV/mA level, e.g. 90kV/12mA (see Operating
Instructions).
2. Make the SIDEXIS 4 ready for exposure.
3. CAUTION! Activating the release button triggers X-rays.
Activate the release button and take the voltage drop reading on the
multimeter display.
If the measured voltage drop does
not fall within the permissible
tolerance range
(see the following table), notify the customer that
a suitable line voltage (according to the notes listed in the
Installation Requirements) must be installed.
If the measured voltage drop falls within the permissible
tolerance range (see the following table), finalize the
measurement.
Permissible voltage drop:
Concluding the measurement
1. Switch the unit on via switch (A) (see also Operating Instructions).
2. Disconnect the unit from the junction box of the building installation.
3. DANGER! Wait at least 1 minute after disconnecting the unit from the
junction box of the building installation before removing the
measuring wires!
Remove the measuring units from the unit.
4. Re-attach the "Bottom profile" cover to the unit.
IMPORTANT
In such a case, the unit must be switched off immediately and
disconnected from the junction box of the building installation. It must
not be placed in operation!
