CIENTIFIC
When the unit shows more than one status code, it adds the codes together
and displays them as a decimal sum. For example, if the unit displays a
Memory status code (listed as hexadecimal number “(H)1” on the
instrument’s specific status code table) and a Valve A status code (listed as
hexadecimal number “(H)4” on the instrument’s specific status code table)
at the same time, the two status codes (when downloaded) would be
displayed as the decimal number “5.”
The decimal number “5” must then be converted back to hexadecimal (in
this case also “5”) to match the status code table. Only two status codes
would add up to a value of 5 (Table A-2). By looking at instrument’s
specific table and breaking down the downloaded status codes, you will be
able to decipher which status codes the unit has displayed. Repeat the
operation for each place in the hexadecimal code (10’s, 100’s, etc.).
For example, decipher the following decimal status code (8433666) for an
instrument with the given example status code table (Table A-3).
First convert the decimal status code downloaded from the monitor to a
hexadecimal number using the Windows (or another scientific) calculator:
8433666= (H)80B002
