• Press coarse/fine detection button. The

instrument is ready for fine detection.

• Move the instrument slightly up and

downwards like the coarse detection

procedure.

• When the instrument displays as shown

in the figure, it is at the right position.

• Tighten the clamp bolt and mark the position of the object on the

rabbet. This mark will be the horizontal reference of the fine detection.

(e) Sound function

• If the instrument is working in a circumstance that makes it difficult

to use the display function, the sound function can be used instead.

• Press the sound function button. The sound symbol is displayed

which means it is ready for sound function. The instrument then

conducts coarse/fine detection through sound (buzz) signals.

• When the sound signal is ultra-short buzz, move the instrument

slightly upwards.

• When the instrument makes short buzz, move it slightly downwards.

• When the instrument makes intermittent, continuous sound, it is at

the right position.

• If there is no buzz heard, the instrument has not received the laser

scanning signal.
