Converting Data to Physical Quantities
Data converted from analog to digital is 2-byte integers from -32768 to +32767.
When the input is +/-100% of the set input range, the value is +/-25000.
The input value is obtained from the following formula:
Input value = (A/D conversion value of the data file) x SLOPE + Y_OFFSET
z
About the tachometer pulse input data
25,000 is 100% range value at 16 bits mode.
1,638,400,000 is 100% range value at 32 bits mode.
The LX-20/20L records the tachometer pulse input data by reflecting the number of pulses per revolution
and /or the pre-set divided rate.
