Storing/Adding Measured Values
Push the memory add button 3 in order to store the current measured value – a length, area or volume value, depending on the current measuring mode.
As soon as a value has
been stored, “M” is
indicated in the display and “Add” is briefly indicated next to it.
If a value is already stored in the memory, the new value is added to the memory contents, however, only if it’s the same type of measurement.
As an example, when an area value is in the memory and the current measured value is a volume value, the addition cannot take place. “Err.” briefly flashes in the display.
However, values of the same type (e.g. length values) can be added no matter if they have been measured in feet and inches, decimal feet or meters.
Subtracting Measured Values
Push the memory subtraction button 2 in order to subtract the current measured value from the memory value. As soon as a value has
been subtracted, “M” is indicated in the display, and is briefly followed by “Sub.”
If a value is already stored, then the new measured value can be subtracted only when the measures of unit correspond (see “Storing/Adding Measured Values”).
Displaying the Stored Value
Push the memory retrieve button 11 in order to display the value stored in the memory. “M=” is indicated in the display.
When the memory
contents “M=” is indicated in the display, it can be doubled by pushing the memory add button 3 or
set to zero by pushing the memory subtract button 2.
The memorized values can only be displayed in decimal feet or meters.
Deleting the Memory
To delete the memory contents, first push the memory retrieve button 11 so that “M=” is indicated in the display. Then push the clear button 1; “M” is no longer indicated in the display.
Operating Instructions
The reception lens 20 and the laser beam outlet 19 must not be covered when taking a measurement.
The rangefinder must not be moved while taking a measurement (with the exception of the continuous measurement mode). Therefore, whenever possible, place the rangefinder against or on the measuring points.
Measurement takes place at the centre of the laser beam, even when target surfaces are sighted at an incline.
The measuring range depends upon the light conditions and the reflection properties of the target surface. For improved visibility of the laser beam when working outdoors and when the sunlight is intense, use the laser viewing glasses 22 and the laser target plate 23 (optional accessories), or shade off the target surface.
When measuring against transparent surfaces (e.g. glass, water) or reflecting surfaces, faulty measurements are possible. Also, porous or structured surfaces, air layers with varying temperatures or indirectly received reflections can affect the measured value. These effects are due to physical reasons and can therefore not be compensated for by the rangefinder.
Sighting with the Alignment Aid (see figure G)
With the alignment aid 7, sighting over larger distances is a lot easier. For this, look alongside the aligning aid on the top side of the rangefinder. The laser beam runs parallel to this line of sight.
Measuring with the Extension Pin
(see figures B and H)
The extension pin 14 is suitable for measuring from inside corners (to measure diagonals) or from hard to reach areas, such as from roller- shutter rails.
