9. Remove the grounding set from the test object.
10.Turn on the CPC 100 at its mains power switch at the left-hand side.
11. An error message (313) appears if there is no ground connection, neither via
PE (protective earth wire of the power supply) nor via grounding terminal or
the power supply has no galvanic connection to ground. The latter is the
case on very special power supplies like with diesel generators or when
insulation transformers are used.
12. If the PE and grounding terminal connection are intact and the error
message still appears, select the "Disable ground check" check box at the
Device Setup tab in the Options view.
Note: After the CPC 100 has been rebooted, the "Disable ground check" check
box is cleared for safety reasons.
13. The green warning light "O" lights up, showing that the CPC 100 output does
not carry a dangerous voltage or current yet.
Note: If none or both warning lights are on, the unit is defective and must not be
used anymore.
4.3 Measurement
1. Set up your test in the CPC 100 software.
For a detailed description of how to use the software refer to respective
section in the CPC 100 Reference Manual.
2. Selecting the TanDelta - PF test card from the CPC 100’s menu
automatically turns on the CP TD1. If no CP TD1 is connected to the
CPC 100, an error message occurs.
3. Set up your measurement in the TanDelta - PF test card (see 3.1 on
page 25).
Warning: Establish a barrier to the high-voltage area.
Warning: This is a safety-relevant message. If the reason for this message is
that neither PE nor grounding terminal is connected, it can cause injury or
possibly death of the operating staff.
For safe operation always make sure that both PE and grounding terminal are
connected.
