The 16 data channels are numbered from 0 to 15 : Blank, Volt. reference, Press. supp., Press. offset, Temp. supp., Temp. offset, Cond. supp., Cond. offset, Bottle trip flag, Touch down flag, Press. supp., Press. offset, Temp. supp., Temp. offset, Cond. supp., and Cond. offset. Data file is formatted as 16I6. Note that the number which appeaars in column 1 may not be channel 0 (because record may be out of sync.) Example : the address bit of number 7770 indicates it is channel 1, hence it is Volt. reference.
