Calibration - LTL2000SQ

A calibration should always be carried out before starting a new series of measurements.

The LTL2000SQ is supplied with two calibration units. One for Rl and one for Qd.

The order of R1 / Qd calibration is not critical. Qd calibration can be done before the Rl cali- bration and reverse. The Rl / Qd calibration can also be performed individually.

The Qd calibration only consist of one calibration (no zero calibration is needed).

Calibration is done by placing the calibration unit underneath the instrument between the rails. The easiest way to place the unit is to tilt the instrument backwards, see picture page 6. The calibration units are fitted with guidance pins on the outside. The pins mounted in the middle of the longitudinal direction of the unit shall fit in the notch in the rails, see figure 2 page 9.

The instrument automatically compensates for zero signal, leakage and other possible error sources, and calculates the calibration factor. This process is fully automatic and if the cali- bration routine is followed precisely the retroreflectometer will now measure “true” Rl / Qd.

Calibrate:

Press the key to enter calibration mode.

If only Rl or Qd mode is enabled then this mode is the only one shown. In the example both Qd and Rl are enabled.

The display will show:

Calibration

= Qd = Rl

Use or key to activate the wanted calibration sequence.

Qd Calibration:

Follow the instructions in the display.

Note:

Step 1: The vertical black plate on the calibration unit shall face forward (see figure 2 page 9).

Step 2: The message will be shown for a couple of seconds.

Step 3: Edit the Qd Normal value according to the value printed on the calibration unit.

The display shows:

Step 1

Step 2

Mount Qd Normal when Ready

Calibrating Please Wait

Step3

Qd Normal: 200

= OK to Edit

Step 4

Qd Normal: 215 = when OK

Step 5

Calibration Done Remove Normal
