Clipping indicator cannot be cleared

Question:

When starting the PATCHMASTER software today I got the following error message:

"EPC10_USB clipped indicator cannot be cleared"

This message appeared suddenly. What can I do?

Answer:

- Please disconnect every other device which might be connected to the EPC 10 amplifier.
- Switch off the amplifier and check for the proper connection of the headstage/probe to the amplifier. If you connect it you should hear a "Click" sound.
- Shield the headstage/probe with the BNC cap provided by HEKA (it has a red rubber plate inside). Some other BNC caps may have a small metal pin inside causing a short circuit.
- Check if the housing of the headstage/probe is electrically insulated from the micromanipulator.

If this does not help please contact the support team. An inspection of your amplifier is necessary.
