Calibrate the RL value by following these steps:
•
Select ‘Calibrate’ from the main menu.
•
Type in the RL-calibration value printed on the calibration target sticker.
•
Place the calibration target under the LTL3000 (in the front)
and press ‘Calibrate RL’ on the screen.
Note: the pins on the calibration target fit into the slots underneath the LTL3000 instrument.
•
Wait for success confirmation.
RL Dark calibration (occasionally)
Normally, it is sufficient to make a reference calibration of the LTL3000 instrument prior to conducting
measurements. However, if the instrument in rare occasions measures incorrectly it is recommended to do a
dark calibration.
To do a dark calibration follow these steps:
•
Select ‘Calibrate’ from the main menu.
•
Press ‘RL Dark calibration’ on the screen.
•
Tilt the instrument backwards and make sure it is not pointing at anything within several meters.
•
Press OK and wait for success confirmation.
•
Important: Perform Reference RL calibration (see above)
Reference Qd calibration (never):
The instrument is factory calibrated for the Qd value and thus Qd should not be re-calibrated.
Qd calibration requires a Qd calibration marking (optional). The instrument will warn about this fact before
calibration.
Special Qd calibration marking.
Note: Be aware that it is NOT possible to recover the factory calibration if the Qd value is recalibrated.
To calibrate the Qd value follow these steps:
•
Select ‘Calibrate’ from the main menu.
•
Type in the Qd calibration value printed on the calibration target sticker.
