4.0 TAKING A MEASUREMENT
NOTE: Before taking a measurement, be sure that the correct unit of
measurement (g or cN) has been selected and a zero adjustment
has been performed.
4.1 Inserting the process material
1. Press the LEVER to tilt the outer GUIDE ROLLERS sidewards.
2. Thread the PROCESS
MATERIAL through the
MEASURING and
GUIDE ROLLERS
(ilament guide).
3. Slowly release pressure on
the LEVER until the GUIDE
ROLLERS returnto their
original position.
NOTE: It is important to
assure that the PROCESS
MATERIALruns smoothly
between the MEASURING
and GUIDE ROLLERS.
4.2 Measuring the process
material
The DISPLAY now shows the
measured tension values. Error
messages which might be displayed
are described in Sec. 6.5.
4.3 Removing the process material
1. Press the LEVER and remove the PROCESS MATERIAL.
2. Slowly release pressure on the LEVER until the GUIDE ROLLERS
return to their original position.

2. Release the RECALL key when the value shown on the Display is fairly stable
(the reading might luctuate greatly).
3. The Display shows E –10
o 1st calibration point: o
1. Hang a weight which
corresponds to 10% of
the tension range from the
measured material, vertically,
as shown.
2. Press the LEVER down
all the way. Thread the
PROCESS MATERIAL
through the MEASURING
and GUIDE ROLLERS.
Slowly release pressure on
the LEVER until the GUIDE ROLLERS return to their original position.
3. Before starting the calibration, move the instrument slowly up and down to
compensate for possible mechanical friction losses and thus ensure repeatability of
the measurements.
4. Press the RECALL key. As long as the RECALL key is
depressed, the DISPLAY shows a decimal value which is
higher than the irst decimal value, e.g., 3500. This decimal
value may vary from instrument to instrument.
Write down the value
5. Release the RECALL key when the value shown on the
DISPLAY is stable (the reading might luctuate greatly).
The DISPLAY shows
o 2nd calibration point: o
1. Repeat steps 1 through 4 above using a weight which corresponds to 40% of the
tension range
2. Press the RECALL key. As long as the RECALL key is
depressed, the DISPLAY shows a decimal value which is
higher than the second decimal value, e.g., 6000. This decimal
value may vary from instrument to instrument. Write down the
value
3. Release the RECALL key when the value shown on the
DISPLAY is stable (the reading might luctuate greatly).
The DISPLAY shows E –70
