8.6.3. Disk-On-Module Replacement Procedure
NOTE
Servicing of circuit components requires electrostatic discharge protection, i.e. ESD grounding straps,
mats and containers. Failure to use ESD protection when working with electronic assemblies will void the
instrument warranty. Refer to Section 9 for more information on preventing ESD damage.
Replacing the Disk-on-Module (DOM) will cause loss of all DAS data; it may
also cause loss of some instrument configuration parameters unless the
replacement DOM carries the exact same firmware version. Whenever changing
the version of installed software, the memory must be reset. Failure to ensure that
memory is reset can cause the analyzer to malfunction, and invalidate
measurements.
After the memory is reset, the A/D converter must be re-calibrated, and all
information collected in Step 1 below must be re-entered before the instrument
will function correctly. Also, zero and span calibration should be performed.
1. Document all analyzer parameters that may have been changed, such as
range, auto-cal, analog output, serial port and other settings before replacing
the DOM.
2. Turn off power to the instrument, fold down the rear panel by loosening the
mounting screws.
3. When looking at the electronic circuits from the back of the analyzer, locate
the Disk-on-Module in the right-most socket of the CPU board.
4. The DOM should carry a label with firmware revision, date and initials of the
programmer.
5. Remove the nylon standoff clip that mounts the DOM over the CPU board,
and lift the DOM off the CPU. Do not bend the connector pins.
6. Install the new Disk-on-Module, making sure the notch at the end of the chip
matches the notch in the socket.
7. It may be necessary to straighten the pins somewhat to fit them into the
socket. Press the chip all the way in.
8. Close the rear panel and turn on power to the machine.
9. If the replacement DOM carries a firmware revision, re-enter all of the setup
information.
