STATIC-SENSITIVE PARTS
MOS devices are designed to operate at very high impedance
levels. As a result, any normal static charge that builds up on
your person or clothing may be sufficient to destroy these
devices if they are not handled properly. Table 5-4 lists those
parts used in the Models 868 and 869 that might be destroyed
by static charge. When handling these devices, use the following
precautions:
1. Transport and handle these parts only in containers
designed to prevent static build-up. Typically, these parts will
be received in static-protected containers of plastic or foam.
Keep these devices in their original containers until ready for
installation.
2. Remove the devices from their protective containers only at a
properly grounded work station. Also ground yourself with a
suitable wrist strap.
3. Handle the devices only by the body; do not touch the
terminals or pins.
4. Any PC board into which the device is to be installed must
also be properly grounded.
5. Use only anti-static type solder suckers.
6. Use only grounded soldering irons.
7. Once the device is installed on the PC board, it is normally
adequately protected, and normal handling may resume.
CAUTION
This assembly contains electrostatic sensitive devices which
can be damaged by static discharge when touched. Observe
precaution when handling.

PERFORMANCE VERIFICATION
This performance verification procedure should be accomplished
after any parts replacement or circuit repair, or to check instrument
operation at any time incorrect operation is indicated.
