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

Normal operation Manually fine adjustment S2 / S3 , S4|4 (int), S4|5 (ext) & S7&S8
