2.2 Battery Management & Charging
The tension meter has a built-in rechargeable LiPo battery, which has been charged at
the factory. The tension meter can only be switched on if the battery has enough charge.
If the instrument does not power up or if the battery level indicator shows only one bar
after power-up the battery needs to be recharged.
NOTE: To ensure maximum battery life, avoid discharging it completely or charging it
frequently for short periods. The battery should not be stored for a prolonged time when
empty. After a maximum storage period of one year, the battery has to be recharged.

Charging the Battery
NOTE: The battery must be charged at a temperature between +5 °C and
+45 °C. Before connecting the AC adapter, verify that the supply voltage is
correct (100 V – 240 V). Electromatic provides no warranty or liability for
damage resulting from the use of AC adapters from other manufacturers.
To charge the battery, connect the cable of the AC adapter to the USB output. When
the battery is fully charged, the battery level indicator will show 3 bars
The charging time is approx. 3 ½ hours. Battery overcharging is not possible.

5.0 DAMPING MODE
8.0 CALIBRATION
The tension meter is equipped with an electronic damping that ensures steady readings
when tension ucutates. This is achieved by averaging the measured values at the preset
update rate.
5.1 Switching On the Damping Mode
NOTE: Before switching on the damping mode, it is recommended that you measure
the rst values without damping enabled.
1. Insert process material as described in section 4.1.
2. Press and hold the DAMP key. The display shows the currently set damping factor.
3. Release the DAMP key. The display shows DAMP below the
currently measured value.
5.2 Switching Off the Damping Mode
1. Press and release the DAMP key. If display shows only the
currently measured value, damping is off.
5.3 Changing the Damping Factor
The tension meter is factory preset to a damping factor of 12. The tension values are
thereby averaged for the display in the following way:
12 old values + 4 new values
16
The damping factor can be modied in 15 steps from 01 = low damping:
1 old value + 15 new values
16
to 15 = high damping:
15 old values + 1 new value
16
1. Switch on the tension meter
2. Press and hold the DAMP key. The Display shows the set damping factor.
3. You can now increase the damping factor by pressing the MEM key and
decrease it by pressing the RECALL key.
4. Release the DAMP key to return to the measuring mode.
NOTE: The selected damping factor remains stored in memory even
after the gauge is turned off.

8.1 Dynamic Calibration of the ETX
All tension meters are calibrated with standard materials—such as polyamide
monolament (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.
Line speed Vmax. = ETMB 100 m/min
Vmax. = ETMPB 60 m/min
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 deection pulley when you calculate the suspended weight. Pay attention to the correct
unit of measure cN.
NOTE: The gauge has been calibrated dynamically according to factory procedure.
Therefore, differences may occur between static and dynamic readings.
8.2 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%,40%, 70% and 100% 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 E –0
2. Release rst the POWER key and then the MEM key.
To calibrate the zero point:
1. Press the RECALL key. As long as the RECALL key is
depressed, the Display shows a random decimal value between
–2000 and 2000, e.g. 800 cN. This decimal value may vary from
instrument to instrument.Write down the decimal value.
NOTE: If the value is outside this range, calibration cannot be guaranteed.

7.0 STATIC VERIFICATION OF MEASURING ACCURACY
6.0 STORING AND RECALLING TENSION VALUES
All tension meters are calibrated with standard materials—such as polyamide
monolament (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.
Verication 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 down 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 Sec 8.0
