, KeMes A2xx starts by calibrating the acceleration sensor. The
display indicates " " until the idle state has been reached. When
the upper tool moves downward, the measurement operation is started.
After decompression, the measured angle is indicated on the display.
If the indicated angle value is flashing, only few measured values are avail-
able for determining the angle, and the displayed value is possibly incorrect.
By increasing the decompression path before the upward movement of the
press beam, the time for the measurement of the angle can be extended.
The correct final angle can only be measured if decompression has been
completed and the workpiece has fully sprung back. In addition, the work-
piece can be left in the die somewhat longer after bending has been com-
pleted.
By adjusting the

menu item, this operating mode can also be used for electric
press brakes, limited press beam openings or press brakes in which the
press beam moves very slowly.
5.6 Execution of the manual measurement
For executing a manual measurement, use of the measuring aid is recom-
mended. This allows the measurement result to be reached in less time and
with greater accuracy. In many cases, measurement accuracy is also greater
because the measuring aid makes it possible to align the device parallel to
the bending edge.
Minimum leg length
For manual measurement using the measuring aid, the following minimum
leg lengths apply, depending on the angle to be measured:
Angle Minimum leg length
30° 50 mm
60° 35 mm
90° 25 mm
120° 20 mm
150° 10 mm
Installation of the measuring aid
To install the measuring aid on the device, proceed as follows:
