Qd Dark 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). See above
The instrument will warn about this fact before calibration
Note: Be aware that it is NOT possible to recover the factory calibration if the Qd value is recalibrated.
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 ‘Qd Dark calibration’ on the screen.
•
Tilt the instrument backwards and make sure it is not pointing at anything within a few meters.
•
Press OK and wait for success confirmation.
•
Important: Perform Reference Qd calibration (see above)
