Calibration; Calibration Flow - M-system M3LU2 Operating Manual

10. CALIBRATION

'Calibration' means I/O ranging or output fine adjustments using the front control buttons. M-System's 'One-Step-Cal' cali-
bration technique realizes automatic I/O ranging and adjustment.
This chapter describes flow and operation procedure of the calibration.
You can also carry out the calibration using the PC Configurator Software (model: M3LUCFG). For detailed information,
refer to the M3LUCFG users manual.

The calibration includes I/O Ranging Mode and Fine Adjustment Mode. Hold down the MODE button to shift each mode
