There are many CMOS devices installed in M3500A. CMOS devices are
static sensitive and can be destroyed by electrostatic discharge during
handling. Handle these devices with following precautions to avoid
damaging them:
1.
Transport and handle ICs only in containers designed to prevent
static charge.
2. Disassemble instruments only in a static-free area.
3. Ground yourself with a suitable wrist strap.
4. Handle the devices only at a properly grounded work station.
5. Minimize handling and do not touch the pins during handling the
devices.
6. Remove all plastic, styrofoam, vinyl, paper and other materials that
may generate static from your work station.
7. Only use grounded tip solder irons and anti-static type solder
suckers.

If a circuit board is removed during repair or a component is replaced,
the M3500A must be recalibrated for accuracy.
