Principal procedure of a 90° measurement with WYLER LEVEL SOFT
The angular error of the instrument must be determined (optional)
The measurement follows the required set-up (Step length, number of measurements etc.)
After the measurement the respective lines may be adjusted according to different methods. For the following
three methods the angular errors are computed and displayed:
•
Method Endpoints
•
Method ISO1101
•
Method Linear regression (least square)

A principal procedure of a measurement of a line with WYLER instruments is described below:
Example:
•
Sensitivity of the instrument 1 µm/m
•
Length of measuring base 200 mm/ step length 180 mm
•
The line to be measured must be divided in equal sizes according to the base available (calculated
step length) Overlapping of the steps is important, otherwise measuring errors are inevitable.
•
Place the instrument at the begin of the line measurement
•
Slide the instrument step by step along the line to be measured. Note all the measuring results after
allowing enough settling time. Then the line can be drawn as shown below considering the base
length and the sensitivity of the instrument.
This shows the
measurement of a line using
LEVELTRONIC „NT“ and a
LEVELMETER 2000
The data transfer is done via
radio module
Measurements on granite surface plates are done with instruments equipped with hardened steel bases with
dust groves. The sharp edges prohibit dust particles to get between the plate and the base when sliding the
instrument.
The manual measuring and the computing effort is quite big if possible at all and the source of errors large.
Such a task is best done with the
WYLER LEVEL SOFT 99.
