9.0 CALIBRATION

9.1 Dynamic Calibration of the ETX

All tension meters are calibrated with standard materials—such as

polyamide monofilament (PA)—ccording to the factory procedure. The

diameters are given in section 1.0. In 95% of all industrial applications, the

factory calibration has been proven to provide the best results and is used

for comparative purposes. The basic setup for a dynamic calibration is

shown below.

9.2 Static Calibration

NOTE: The tension meter is factory calibrated for a vertical material path

Recalibration thus also has to be carried out with a vertical

material path.

Before beginning:

Acquire one cN weight each (or several weights adding up to the required

value), corresponding to 10%, 50% and 90% of the tension range. Make

sure the tension meter is switched off and that no process material is

inserted between the rollers.

To select the calibration mode:

1. Press and hold the MEM and POWER keys until

the Display shows

2. Release first the POWER key and then the MEM key.

To calibrate the zero point:

1. Press the MEM key. As long as the MEM key is

depressed, the Display shows a random decimal

value between 500 and 1200, e.g. 800 cN. This

decimal value may vary from instrument to

instrument.Write down the decimal value.

2. Release the MEM key when the value shown on the

Display is fairly stable (the reading might fluctuate

greatly).

3. The Display shows

ijkl mnllo pqrst u vwx yzz q{qjk | pqrst u vwx} ~z q{qjk

Hang twice the weight (pulley effect) which corresponds to the

tension to be measured from the measured material, vertically,

as shown here. Please keep in mind to include the weight of

the lower deflection pulley when you calculate the suspended

weight. Pay attention to the correct unit of measure cN.

6.1 Memory Mode Selection

1. Switch on the tension meter

2. Clear the memory by simultaneously pressing the MEM and RECALL

keys.

3. Press and hold the MEM key.

The Display shows “S”. This is the Standard Memory

Mode (default). Press the DAMP or RECALL to display

the other memory modes.

Memory mode C (CONTINUOUS):

If the Display shows C, the CONTINUOUS memory

mode is set.

Memory mode L (LIMIT):

If the Display shows L, the LIMIT memory mode is set.

Memory mode F (FAST):

If the Display shows F, the FAST memory mode is set.

When you have selected the desired memory mode, you can release the

MEM key. The selected memory mode is now active and the tension meter

switches back to measuring mode.

NOTE: The selected memory mode remains stored in the memory even

after the instrument is switched off.

6.2 Data Logging in Mode S (Standard)

1. Turn on the tension meter.

2. Memory Mode S set as described in section 5.1

3. Insert process material and begin measuring as described in section 4.0.

To Start Data Logging:

1. Press and hold the MEM key until the Display

shows the memory mode “S” and the current

memory number.

2. Release the MEM key. The tension meter starts logging

the data.While the tension data are stored, the MEM

indicator blinks on the Display and the currently

measured value is displayed.

8.0 STATIC VERIFICATION OF MEASURING ACCURACY

All tension meters are calibrated with standard materials—such as polyamide

monofilament (PA)—according to the factory procedure. The diameters are

given in section 1.0. Any difference in process material size and rigidity from the

standard material may cause a deviation of the accuracy.

In 95% of all industrial applications, the factory calibration has been proven to

provide the best results and is used for comparative purposes.

NOTE: Before beginning, make sure that the tension meter is factory calibrated

for a vertical material path. The required reference weight is available.

Verification procedure:

1. Switch on the tension

meter.

2. Hang a weight which

corresponds to the tension

to be measured from the

measured material,

vertically, as shown.

NOTE: Pay attention to the correct unit of measure cN or g (gram).

3. Press the LEVER down all the way and thread the process material through

the MEASURING and GUIDE ROLLERS as described in section 4.1, then

slowly release pressure on the LEVER until the GUIDE ROLLERS return to

their original position.

4. Before verifying the calibration, move the instrument slowly up and down

to compensate for possible mechanical friction losses and thus ensure

repeatability of the measurements.

5. The tension value shown on the Display should be equal to the value of the

suspended weight (pay attention to the measuring units).

If this procedure shows a deviation, you can recalibrate the instrument following

the directions in secton 9.0
