Converting Data to Physical Quantities

In case of 16 bits AD, the AD conversion value is an integer ranging from –32768 to +32767 and the value

would be ±25000 when the input is ±100% in the input range settings. In case of 24 bits AD, the AD

conversion value is an integer ranging from –8388608 to 8388608 and the value would be ±6400000 when

the input is ±100% in the input range settings. The input value is obtained from the following formula:

Input value = (A/D conversion value of the data file) x SLOPE + Y_OFFSET

■ Data of tachometer pulse input on LX-120

25,000 are 100% range value at 16 bits mode.

1,638,400,000 is 100% range value at 32 bits mode.

The LX-120 records the tachometer pulse input data by reflecting the number of pulses per revolution and

/or the pre-set divided rate.
