2.6 Zero Adjustment of the Measuring Position (Auto Zero)
Each time the tension meter is turned on (before starting measurement),
you need to carry out zero adjustment, as described below. This procedure
is necessary to compensate for the weight of the measuring roller in the
measuring position. The zero adjustment for the new measuring path only
remains effective until the instrument is switched off.
NOTE: Zero adjustment must be repeated whenever the material path is
changed or the tension meter does not display “0.”
NOTE: Before beginning the zero adjustment, you must select the unit of
measure as described in section 2.5.
1. Turn off the tension meter. Process material must not be inserted at this
point.
2. Hold the gauge in the desired measuring position. Be careful to hold the
gauget absolutely steady.

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
