3.1 Weight adjustment
The anti-vibration table AV1 and AV5 can be used to hold equipment with a weight
from 15 to 72 kg. However, the table needs to be installed correctly to have the
optimal anti vibration ability.
NOTE: Before proceeding it is important that you know the exact weight (in
Kg) of the equipment, which you will place on the anti-vibration platform.
When AV1 or AV5 leaves the factory it is equipped with 3 springs and an extra
weight plate. See right column in the table below. The yellow areas indicate the
optimal working conditions for the 3 different installation methods.
Example:
The total weight of equipment placed on the anti-vibration platform with 3
springs should be in the range from 45- 72 Kg.
The Anti-vibration table can be modified in 2 steps to gradually work optimal with
less heavy equipment on the platform.
Step 1: To work with equipment from 30-45 kg one spring is removed so only 2
springs are used.
NOTE: Only remove the middle spring, when needed.
Step 2: To work optimal with equipment from 15-30 kg 2 springs are installed and
an extra weight plate must be used.
