Calibration parameters (Auto/Manual calibration)

3. Programming:

Read/write module data via FROM/TO instructions or use GX Works3 dedicated instructions

Digital-to-analog conversion formula: Analog output value = Digital value × Range / 32000 (unipolar) oder 64000 (bipolar)

4.3 Calibration Process

1. Auto Calibration: Execute “Auto Calibration” function in GX Works3; the module automatically completes zero and gain calibration
2. Manual Calibration:

Short-circuit output terminals, adjust zero potentiometer to achieve 0 output

Input full-scale digital value, adjust gain potentiometer to achieve full-scale output

3. Calibration Cycle: Recommended every 6 months; shorten to 3 months in harsh environment
