Disassembly and Repair
To Replace a Current Input Fuse
Electrostatic Discharge (ESD) Precautions
Both the mA and the A current input terminals are fuse protected. The
fuse for the mA input terminal is located on the front panel (see
The fuse is a 0.63 mA, 500 V fuse, Agilent part number 2110- 1432. If you
determine that the fuse is faulty, replace it with one of the same size and
rating.
The fuse for the A current input terminal is located inside the multimeter
(see
is a 25 A, 440 V fast- acting fuse, Agilent part number 2110- 1431. If you
determine that the fuse is faulty, replace it with one of the same size and
rating.
Almost all electrical components can be damaged by electrostatic discharge
(ESD) during handling. Component damage can occur at electrostatic
discharge voltages as low as 50 volts.
The following guidelines will help prevent ESD damage when servicing the
instrument or any electronic device.
• Disassemble instruments only in a static- free work area.
• Use a conductive work area to reduce static charges.
• Use a conductive wrist strap to reduce static charge accumulation.
• Minimize handling.
• Keep replacement parts in original static- free packaging.
• Remove all plastics, foam, vinyl, paper, and other static- generating
• Use only anti- static solder suckers.
