pressing the "Plus" key. The previous three
measurement and calculation results will
be in the intermediate displays.
8.5 Subtracting distances
Single distances can be conveniently
subtracted from each other. This is useful
for determining, for example, offsets to
inaccessible places or the distance from
the underside of a pipe to the ceiling. To do
so, the distance from the floor to the
underside of the pipe is subtracted from
the distance from the floor to the ceiling. If,
additionally, the pipe diameter is deducted,
the result is the distance from the top of
the pipe to the ceiling.
1. Press the "Measure" key.
(The laser beam will be switched on.)
2. Aim the range meter at the target.
3. Press the "Measure" key.
The first distance will be measured and
shown.
(The laser beam will switch off.)
4. Press the "Minus" key for subtraction.
The first distance will appear in the
middle intermediate result line and a
minus sign in the lowest one.
(The laser beam will switch on.)
5. Aim the range meter at the next target.
6. Press the "Measure" key.
The second distance will be measured
and shown in the bottom intermediate
result line. The result of the subtraction
will appear in the result line.
The current difference between
distances is always shown in the
result line.

This procedure can be followed until all
distances have been subtracted.
To terminate the subtraction of distances,
simply measure a distance without first
pressing the "Minus" key. The previous
measurement and calculation results will
be shown in the intermediate displays.
8.6 Indirect measurement
An indirect distance can be determined by
taking several distance measurements and
calculating according to Pythagoras's
theorem.
The functions for indirect measurement are
called by pressing the "Indirect distance
measurement" function key.
When doing so, there are two possibilities:
the combined version using three
measured distances
(Press the function key
once.)
the simple version using two
measured distances
(Press the function key
twice.)
The simple version is suitable when a
rectangular reference exist such as two
perpendicular walls or a floor adjacent
to a vertical wall.
The combined version is more suitable for
a free determination where it is not
possible to measure a perpendicular dis-
tance to one end of the distance to
be calculated.
- NOTE -
The result of indirect measurement is, due
to principle less accurate than direct
