CLEAR Key
Pushing the
CLEAR - key {A, 5} clears the last entry
or measurement. Within a function (area, volume,
etc.) single measurements can be deleted step by
step and re-measured.
Illumination
Pressing the
ILLUMINATION -
key {
A, 6} turns on the
display backlight
.
Another press turns it off again.
Switching off the device (or automatic switch off)
also turns off the light.
Reference Setting
The default reference setting is from the rear of the
instrument. By pressing the
REFERENCE - key {A, 4},
the setting can be changed, so that the next
measurement taken will be from the "front" of the in-
strument. Afterwards the reference setting automat-
ically defaults back to rear. See picture {
D}.
Measuring
Single Distance Measuring
Pressing
DIST - key {A, 1} turns the laser on. Aim at
the desired target and press DIST - key {
A, 1} again.
The measured distance is displayed immediately in
the chosen unit.
Minimum/Maximum Measuring
This function allows the user to measure the
minimum or maximum distance from a fixed
measuring point as well as to determine spacing - see
figure {
E}. It is commonly used to measure diagonal
distances (maximum values) or horizontal distances
(minimum values).
Press and hold
DIST - key {A, 1} until you hear a
beep, indicating the device is in a continuous
measuring mode. Then slowly sweep the laser back
and forth respectively up and down over the desired
target point - see figure {
F, G} - (e.g. a corner in the
room).
Press
DIST - key {A, 1} again and the continuous
measurement will be stopped. The current values for
maximum and minimum distances are shown in the
display as well as the last measured value in the main
line.
Functions
Addition / Subtraction
Take the first measurement, addition is executed by
pressing the
PLUS - key {A, 2} and subtraction by
pressing the
MINUS - key {A, 8}, then take the next
measurement. This process can be repeated as many
times as is required. The result is displayed in the
main line, whilst the last measurement taken is also
displayed. Pushing the
CLEAR - key {A, 5} undoes the
last step.
