MEASURING CONDITIONS

Measuring range
The instrument’s measuring range is 70m. At night, under poor visibility conditions or if the surface to be measured is in shadow, the measuring range can be reduced. To prevent this, carry out measurements during the day or use luminous plates when the object to be measured has poor reflecting properties.
Object surface
The instrument can give errors when measurements are carried out on colorless liquids (e.g. water), transparent glass, polystyrene, very polished or half permeable surfaces because of the deviation of the laser beam. Non-reflecting surfaces may cause delays when measuring.
Maintenance
Do not immerse the instrument in water. To clean the instrument, use a soft cloth moist with neutral detergent

REPLACING INTERNAL BATTERIES

The instrument is supplied by 2×1.5V AA LR06 alkaline batteries. When the symbol  flashes on the display, it is necessary to replace the batteries. Proceed as follows

1. Slide the battery compartment cover to the right and remove it.
2. Remove the batteries and insert the same number of batteries of the same type, respecting the correct polarity. Only use alkaline batteries.
3. Restore the battery compartment cover into position by sliding it to the left to fasten it again.
   Replacement of the internal battery.

ERROR MESSAGES ON THE DISPLAY
