To Check Plumb; Care And Cleaning; Specific Reasons For Erroneous Measuring Results - ADA INSTRUMENTS Phantom 2D Operating Manual

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 verti-
cal 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 position "OFF". Disregard may lead to damage of compensa-
tor.

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.
