Introduction
The information in this section describes routine maintenance of the instrument that the operator
can perform.
Line fuse replacement
A fuse on the 2470 rear panel protects the power line input of the instrument. Follow the below
instructions to replace the fuse. You do not need to return your instrument for service if the fuse is
damaged.
Disconnect the line cord at the rear panel and remove all test leads connected to the
instrument before replacing a line fuse. Failure to do so could expose the operator to
hazardous voltages that could result in personal injury or death.
Use only the correct fuse type. Failure to do so could result in injury, death, or instrument
damage.
Use a 5 x 20 mm slow-blow fuse rated at 250 V at 2 A.
To replace the fuse, you will need a small, flat-bladed screwdriver.
