6.4.10 MEASUREMENT OF RECTANGULAR OBJECTS
The following options are possible. Please be sure to note which of the lines is the reference-line (sha-
ded gray):

reference line

The first step is the determination of the instrument’s error, which is done by two reversal measure-
ments (horizontal and vertical) according to the sketch below.
Procedure for the determination of the angular error
of the measuring instrument:
1. Reversal measurement on a horizontally aligned
surface plate
2. Reversal measurement on a master, a cube of
granite with two parallel surfaces in the quality
000
Remark:
For a detailed instruction, please visit our www.
wylerag.com. Under Products>Software>MT-SOFT
there is a video for the procedure.

If the possibility of a reversal measurement on a so-called master is not available, there are the following
alternatives for the input of the angular error:
• If a calibration certificate exists, the value can be transfered from there
• You trust the measuring base and you type in a correction value of “0“
