Loading Correction Constants from Disk

his will load a copy of the CC data that is on disk into temporary RAM. Once in RAM, the
analyzer will continue to use that data until turned o . A warning message will be displayed
if some adjustments have not been done or if the serial number contained in the le does not
match the instrument serial number. o permanently save this data to EPROM, you must also

Storing Correction Constants to EP OM
his will copy the current contents of the analyzer's CC data that is contained in RAM to
permanent storage in the EPROM. his procedure should be done when you are satis ed that
the current correction constants in temporary RAM are complete and correct. Once stored to
EPROM, a backup copy should made on a oppy disk using the \Storing Correction Constants
to Disk" procedure.

Installing Correction Constants from Disk

his procedure automatically loads CCs from disk and stores them in EPROM. his procedure
is typically done after replacing the CPU board assembly in order to return the analyzer to its
previously calibrated state.

Warning: No Correction Constants Installed
install the correction constants from disk using the \Install Correction Constants From Disk"
procedure.
If you suspect that the current CC data is inaccurate, rst try reinstalling CC data using the
\Install Correction Constants From Disk" procedure. If this does not seem to improve the
situation, try erasing all of Static RAM (SRAM) by using the following procedure. Note that this
will erase any data in the non-volatile RAM, but it will not a ect the CC data.
Cycle the the analyzer's power.
After about 8 seconds, the analyzer will emit a double beep. Immediately after this double
beep, press
PRESET
he analyzer will pause after performing the CPU main self-tests and ask if you want to zero
the SRAM. Answer YES by pressing the
When the analyzer completes its power up routine, it will be placed in the factory default
condition. Verify that the analyzer is now producing correct measurement results. If not, the
analyzer may have to be repaired or re-calibrated.
