Change the line voltage
Line voltage is preset at the factory, but may be reset in the field.
If you change the line voltage, you also need to replace the line fuse. Use only the correct
fuse type. Failure to do so could result in injury, death, or instrument damage.
To change the line voltage:
1. Remove the handle from the 6517B.
2. Use a Philips screwdriver to remove the left mounting ear (left when looking at the front panel of
the 6517B).
3. Use a small coin to change the voltage setting.
4. Replace the mounting ear and handle.
5. Replace the line fuse. See
Line fuse (on page 5-2, on page 5-1) for more information.
