3-2 Adjustments
Although this instrument has been designed in accordance with
international safety standards, this manual contains information,
cautions, and warnings which must be followed to ensure safe
operations and to retain the instrument in safe condition. Service and
adjustments should be performed only by qualified service personnel.
Adjustments in this section are performed with power supplied
to the instrument while protective covers are removed. There
are voltages at many points in the instrument which can,
if contacted, cause personal injury. Be extremely careful.
Adjustment should be performed only by trained service
personnel.
Power is still applied to this instrument with the LINE switch in
STANDBY. There is no OFF position on the LINE switch. Before
removing or installing any assembly or printed circuit board,
remove the power cord from the rear of both instruments and
wait for the MAINS indicators (red LEDs) to go completely out.
Capacitors inside the instrument may still be charged even if the
instrument has been disconnected from its source of power.
Use a non-metallic tuning tool whenever possible.
The equipment required for the adjustment procedures is listed
in 'lkble l-l, Recommended Test Equipment, at the beginning of
this manual. If the test equipment recommended is not available,
substitutions may be used if they meet the "Critical Specifications"
listed in the table. The test setup used for an adjustment procedure is
referenced in each procedure.
For adjustments requiring a non-metallic tuning tool, use fiber
tuning tool HP Part Number 8710-0033. In situations not requiring
non-metallic tuning tools, an ordinary small screwdriver or other
suitable tool is sufficient. However, it is recommended that you use a
non-metallic adjustment tool whenever possible. Never try to force
any adjustment control in the analyzer. This is especially critical when
tuning variable slug-tuned inductors and variable capacitors.
