Customer length Calibration
Mount instrument on calibration flanges in a dust-free environment, at theexact distance as measuring path length and power on.
Set switch S2/S3 up, check the optical alignment & make it perfect & setS2/S3 down.
Press switch S5 towards left. The yellow LED starts blinking & system will automatically start calibration
cycle.- LED Int. CALIB- Zero point INTERNAL calibration.- Span calibration- Zero point EXTERNAL calibration- Zero point check- Window check
- Span check
