The following steps require protection against ESD (Electro- Static Discharge).
`
Use a grounded wrist strap (part no. 9300- 0969 - large, or 9300- 0970 - small)
connected to a suitable ground. Failure to heed this caution may result in
damage to the instrument.
When storing or in between handling of PCBs (Printed Circuit Boards), always
`
place them in static control envelopes or enclosures.
9. Remove the detector PCB from the right side of the instrument by grasping it in the center area
along its outer edge and pulling it straight out. (If an interconnect is employed, this will draw it
out of the detector.)
10. Install the replacement detector PCB by sliding it into its mounting location on the main PCB.
(If an interconnect is employed, Installation of the PCB will insert the interconnect into the ther-
mal strap. Use caution to avoid damaging the spring at the end of the interconnect.)
11. In order to install the detector PCB, the components which retain the interconnects (or other
wiring) must be tightened, installed, and/or connected as applicable for a particular detector:
` TCD:
Connect the detector filament and delta- t
temperature sensor leads at their connector
block on the detector PCB. Use a small
flat- blade screwdriver to press each wire
lead release (located adjacent to each con-
nection) while inserting the wire into the
connector block.
