SPECIAL NOTE:
When a 6610XA comes in for calibration or repair and the instrument has a serial number with in
the range shown above the socket may need to be replaced?
To identify if the socket is defective see Figure 2 below for specific details.

intermittent connection will occur.
The pin connections may not be reliable. Over time the pins may become intermittent which will cause
the instrument not to communicate or not complete self test.
