TO CHECK PLUMB
Choose a wall and set laser 5m away from the wall. Mark point A on the
wall, please note the distance from point A to ground should be 3m. Hang
a plumb line from A point to ground and find a plumb point B on ground.
turn on the laser and make the vertical laser line meet the point B, along
the vertical laser line on the wall and measure the distance 3m from point
B to another point C. Point C must be on the vertical laser line, it means the
height of C point is 3m.
Measure the distance from point A to point C, if the distance is over 2 mm,
please, contact with seller to calibrate the laser.
CARE AND CLEANING
Please handle measuring instrument with care. Clean with soft cloth only
after any use. If necessary damp cloth with some water. If instrument is
wet clean and dry it carefully. Pack it up only if it is perfectly dry. Transport
in original container/case only.
Note: During transport On/Off compensator lock (3) must be set to posi
-
tion “OFF”. Disregard may lead to damage of compensator.
SPECIFIC REASONS FOR ERRONEOUS MEASURING RESULTS
•
Measurements through glass or plastic windows;
•
Dirty laser emitting window;
•
After instrument has been dropped or hit. Please check the accuracy.
•
Large fluctuation of temperature: if instrument will be used in cold
areas after it has been stored in warm areas (or the other way round)
please wait some minutes before carrying out measurements.
ELECTROMAGNETIC ACCEPTABILITY (EMC)
•
It cannot be completely excluded that this instrument will disturb other
instruments (e.g. navigation systems);
•
will be disturbed by other instruments (e.g. intensive electromagnet-
ic radiation nearby industrial facilities or radio transmitters).
