Processor Board

Either

• Discard the processor board and send the instrument to a repair facility. A new

processor board will be installed and the instrument will be repaired and calibrated. If

the instrument is still under warranty, you will not be charged for the new processor

board.

• If you have another working instrument, install the processor board into that

instrument and erase the memory. Then reinstall the processor board back into the

non-working instrument and send it to a repair facility for repair and calibration. If

you discover that the processor board does not function in the working instrument,

discard the processor board and note that it caused the instrument failure on the repair

order. If the instrument is still under warranty, you will not be charged for the new

processor board.
