Connecting SPECTANO 100 to a test cell without guard ring
NOTICE
The safe area is only safe if the delivered cables and adapters are used.
Otherwise, this can also be a danger zone.
To connect SPECTANO 100 to a test cell without guard ring:
1. Ground SPECTANO 100 according to the safety rules (see 2.2 "Five safety
rules" on page 5).
2. Connect the standard triaxial cable according to the color code to the
SPECTANO 100 OUTPUT and INPUT connectors:
• Red-labeled cable to the OUTPUT connector
• Blue-labeled cable to the INPUT connector
3. Depending on the test cell connection (BNC or 4 mm plug), connect one of
the adapter cables described earlier in this chapter with the corresponding
color code to the standard triaxial cable:
• Red-labeled adapter cable to the red marked standard cable
• Blue-labeled adapter cable to the blue marked standard cable
4. Connect the adapter cables to the test cell without guard ring according to
the schematic diagram.
Note: If you are using the triaxial-to-4 mm plug adapter cable, be aware that the
inner shield (guard) and the outer shield (ground) are not connected.
For more information and example connections to different types of test cells,
see "Appendix" in the SPECTANO 100 User Manual.
