Maintenance-314 Service
NOTE
The spring tension of the pin socket ensures a good
connection between the circuit board and the pin.
This spring tension can be destroyed by using the
socket as a connecting point for spring-loaded
probe tips, alligator clips, etc.
Lead-End Pin Connectors.
The pin connectors used to
connect the leads to the interconnecting pins arecrimped
to the ends of the leads. To remove and replace damaged
lead-end pin connectors, remove the damaged connector
from the end of the lead and crimp the replacement
connector to the lead.
Some of the pin connectors are grouped and mounted
in a plastic holder. These connectors are removed and
installed in the instrument as a multi-pin connector unit.
To provide correct orientation of the multi-pin connector
with the circuit board, an arrow is stamped on the circuit
board and a matching arrow is molded into the plastic
housing of the connector body. Align the arrows when
connecting to the circuit board.
If individual lead-end pin connectors are removed from
the plastic holder, note the wire color and position of the
individual wires.
Recalibration After Repair
After any electrical component has been replaced,
recheck the calibration of the affected circuit as well as the
calibration of other closely related circuits. Since the low-
voltage supplies affect all circuits, calibration of theentire
instrument should be checked if repairs have been made
to the power supply.
Instrument Repackaging
If the instrument is to be shipped for long distances by
commercial transportation, it is recommended that it be
repackaged in the original manner for maximum protec-
tion. Save the original shipping carton for this purpose.
