(P2) and press
To select the exact position of the weight P2 relative to the Pe unbalance, use 3 o'clock
as a reference if the "H3" configuration is active, or 6 o'clock if the "H6" configuration
is active, or 12 o'clock if the "H12" configuration is active.
The angle between P1 and P2 must be less than 120° and must include the outer
weight Pe.
8 If the angle selected is greater than 120°, the machine displays Fig. 16D for approxi-
mately 3 seconds to indicate that the procedure described in step 7 must be repeated
correctly. If the angle selected is less than 120°, the machine immediately displays
the value for the weight P2. The LED
