3.5 Air Damping
(Optional Accessory Code
A
)
Setting the dashpot:
- Screw in the setscrew clockwise as far as it will go = maximum possible damping. The
screw is protected against overwinding. The damping is now at its maximum setting.
- Turn the setscrew counterclockwise until the desired damping of the pointer is reached,
and the pointer swings are minimal.
The setting range is three counterclockwise revolutions, starting from the maximum
setting.
During operation, as in spooling or winding machines, high frequency tension fluctuation
can occur. This process fluctuation can result in rapid pointer swings which make it difficult
to read the scale. This effect can be reduced by using the built in Air Dashpot Damping
mechanism. The dashpot is infinitely variable and ensures the best readable pointer re-
sults with minimum pointer swings. The air dashpot is built in during production of the ten-
sion meter and can thereforen not be retrofitted.

Setsrew for Air damping
Turn setscrew clockwise
= Increase damping
Turn setscrew counterclockwise
= Decrease damping
Do not screw out the setsrew by more than 5 counterclockwise revolutions;
the setscrew may otherwise fall into the tension meter housing.
