Need different line frequency or voltage
I need to use a Series 3700A at a different line frequency or voltage. What do I need to do?
The Series 3700A only supports a line frequency of 50 or 60 Hz. The line frequency is automatically
sensed and no user action is needed.

Card is not correctly seated in the slot
Check the seating of the card:
1. Remove power from the instrument.
2. Pull the card out of the slot.
3. Carefully guide the card inside the rails while reinstalling.
4. Make sure the outer shield is not inserted into the card rails.
5. Make sure that no other portions of the card catch on any part of the instrument frame while
installing.
