3.4.5 Activating Damping Mode

Damping can only be activated and changed in the tension  
mode.

The tension meter is equipped with an electronic damping which ensures steady read-
ings when tension fluctuates. This is achieved by averaging the measured values at the 
set update rate. Before switching on the damping mode, it is recommended that you 
measure the first values without damping enabled.

Requirements:
- Process material inserted as described in Chapter 3.4.1.
- The DISPLAY has shown the first tension values.

To switch on damping:
- Press the DAMP key.

  The display shows the set damping factor e. g. 

.

- Release the DAMP key. 

  The DISPLAY shows 

2 2 1

.

cN

 DAMP below the currently measured value.

To switch off damping:
- Press the DAMP key.

  The DISPLAY shows 

12

N

 only the currently measured value.

3.4.6 Changing the Damping Factor

The tension meter is factory preset to a factor of 06. The tension values are thereby 
averaged for the display in the following way:
6 old 4 new values

   

10

The damping factor can be modified in 15 steps from 01 = low damping:

1 old value + 9 new values

   

10

to 15 = high damping:

9 old 1 new value

   

10

Requirement:
- Tension meter switched on as described in Chapter 3.3.2.
Procedure:
- Press and hold the DAMP key.
  The display shows the currently selected damping factor.
- You can now change the damping factor with the OFF/ON key.
- Release the DAMP key.
  The tension meter returns to the measuring mode.
