Front Panel Fuse Replacement
WARNING: Make sure the instrument is disconnected from the power line and other equipment
before replacing the AMPS fuse.
1. Turn off the power and disconnect the power line and test leads.
2. From the front panel, use a screwdriver to rotate the fuse carrier several turns counter-clockwise.
Take the fuse carrier out of the socket.
3. Remove the fuse and replace it with the same type (T1AL, 250V, 5×20mm).
CAUTION:
Do not use a fuse with a higher current rating than specified or instrument damage
may occur. If the instrument repeatedly blows fuses, try to find out the reason
before replacing the fuse.
4. Install the new fuse by reversing the procedure above.
