Using the HSA
Figure 11: Diag log file
6. Please email to SPECS, support@spesc.de, these log files to help diagnosis of
the exact problem.
Note: Particularly with analyzer connected, rise time errors are possible be-
cause of a resistance network in the analyzer box and capacitance effects. Es-
pecially the module for Ekin has a higher capacitance to supply and may
cause rise time errors even if the module is okay. Values of 0.8 are within the
limit.
2.3.2 Connection check for the analyzer electrodes
While performing the checks below, it may be useful to refer to the Appendix, sec-
tion 3.3 for the pin assignments of the PHOIBOS feedthroughs.
2.3.2.1 Check all analyzer (HSA) voltages
Check whether the electrode voltages are present at the female contacts of the spec-
trometer plugs. Check the accuracy of the voltage ranges (40V, 400V) with a high
18 HSA3500 / HSA3500 plus Power Supply
