Maintenance and Adjustments
Newport Scientific offers a maintenance and calibration service
for the 8074A. This service should be performed annually.
Alternatively, most wearable parts can be replaced by the user.
To access the serviceable parts inside the monitor, the 8074A
panel must be removed from the carrying case.
Monitor Disassembly and Assembly
WARNING: Unplug the 8074A from power before disassembly.
Even with the power switch off, voltages are present inside the
unit.
Slide the sample tubing off of the front panel elbow.
Use a screwdriver to remove the 5 screws along the perimeter
of the panel holding it in the case. Use the sample tubing elbow
to help lift the panel straight up and out of the case.
When re-assembling the panel into the case, make sure sensor
cable wires are tucked in and not pinched under the panel as
you lower it into the case.
Install the 5 mounting screws, taking care not to cross thread
the screws as you proceed. The screws only need to be snug to
the panel, do not overtighten!
