    _____________________________________________________________________________________________ Chapter 11 Maintenance and Service 11.1 A-Terminal Fuse Replacement (3238/39) To avoid electric shock when replacing the fuse, first disconnect the test leads from the object to be measured. DANGER Replace the fuse only with one of the specified characteristics and voltage and current ratings.

    _____________________________________________________________________________________________ 11.2 Power Supply Fuse Replacement To avoid electrocution, turn off the power switch and disconnect the power cord and test leads before removing the fuse. DANGER Replace the fuse only with one of the specified characteristics and voltage and current ratings. Using a non-specified fuse or shorting the fuse holder may cause a life-threatening hazard.
