2.3.2.4 Fast check of all applied voltages
First run the "Diagnostic tool" as described on page 15. This tool needs no special
equipment and performs a complete check of all generated voltages in the modules
via software.
To check the voltage modules with a high voltage probe (1000:1) and a digital volt-
meter, set the kinetic energy and the workfunction via software (HSA3500 Juggler or
FixedEnergies mode in SPECSLAB 2 ).
The table 12 on page 24 shows an example for EKin=800eV and Ep=20eV in FAT
mode for XPS energy range, the table 13 shows the same for UPS energies.
Tables for former releases can be found in the document "Check-PHOIBOSRx.pdf"
which are supplied by SPECS upon request.
If the measured values are correct, the HSA unit as well as the analyzer box (plug)
and cables are o.k.
Now the voltages can again measured either without the filterbox cable or while be-
ing applied to the analyzer.
The next two procedures should be only carried out by
well trained personnel. Only touch electrical contacts
with the HV-probe.
1.) To exclude the analyzer connection box and the cable, repeat the test
without these connection parts.
Measure the voltages at the rear of the HSA ("Voltages to ground for some
modi (WF = 0), PHOIBOS 100/150 R6 or higher." on page 26). Disconnect the
analyzer box at the rear panel of the control unit. Set a short circuit bridge
between pin C1 and pin C2 at the analyzer output socket (see Appendix sec-
tion 3.2, Rear panel wiring of the HSA, and be sure to use the diagram that
corresponds to your model's wiring type). This bridges the safety interlock if
the analyzer is not connected and enables HV output.
2.) To be able to measure the voltages while applying them to the analyzer the
following procedure is required.
