6. DISPLAY SCREEN
•SETUP Screen
oLCD Refresh Rate
To either speed up or slow down the instrument’s LCD refresh rates:
▪Scroll to SETUP and press ENTER.
▪Scroll to LCD REFRESH RATE and press ENTER.
▪Enter your preference: 1, 2 or 5 Hz and press ENTER.
Note: This feature is unrelated to Data Averaging.
oData Averaging
Use this feature to adjust the stability of your displayed tension readings. It
allows users to select the duration the meter takes tension readings over before
averaging all of the readings and posting that average to the display. The
meter takes ~300 readings per second, so if a 1 second duration is selected,
the meter will average all 300 readings before posting the average of those
readings to the display. Likewise, if a 10-second duration is selected, the meter
will average all 3000 readings before posting the average of those 3000
readings to the display. Options are: 1, 2, 5 and 10 seconds. This is a rolling
average, meaning that only the readings taken in the last 1, 2, 5 or 10 seconds
(your choice) will be averaged and displayed.
Note: This feature is primarily used in processes where the material to be
checked is constantly moving, such as coil winding and textiles.
oCal Analog (Optional feature)
Use this feature to calibrate the Analog Out option by hanging the weight
specified on the screen then entering that numeric value on your Signal
Conditioner (follow the instructions with your signal conditioner)
▪Scroll to SETUP and press ENTER.
▪Scroll to CAL ANALOG and press ENTER.
▪Using the up and down arrows adjust the display to indicate the value
at which the instrument should output maximum Voltage or current.
▪Then press ENTER.
oCal Length (Optional feature)
Use this feature to calibrate the Length measurement option of your instrument.
▪Scroll to SETUP and press ENTER.
▪Scroll to CAL LENGTH and press ENTER.
▪Next, using a precise 20-foot length of your material (20.0’), thread
one end through the instrument’s three rollers and slowly pull exactly
20.0’ through the instrument.
NOTE: The material must be under tension to make good contact
with the rollers on the instrument.
▪Then press ENTER.
oCustom Names
Custom calibrations, listed as Custom 0 –9, can be renamed so your material
appears as a selection on the Main Display. To rename a Custom Calibration:

7. ADVANCED OPERATION
•General Calibration Precautions
1. To verify accuracy or to calibrate your instrument, hang a sample length of
material vertically, and suspend known weight(s) from the opposite end. (See
Figure 9.)
2. When performing this test, use a micrometer to measure your material
diameter and verify it is dimensionally within tolerance and not out of round.
3. Only use free-hanging weights which are traceable to National Standards.
4. Never use any tensioning device that attempts to convert rotational torque
values into tension loads, as these types of systems are highly inaccurate.
Also, any load cell system must be routinely checked for accuracy using
traceable weights, as these types of systems are also highly inaccurate and
generally do not meet minimum repeatable accuracy standards.
•Check Accuracy
1. To check the accuracy of your meter, first hang the test material and suspend
weights from it as described in “General Calibration Precautions” above.
2. Select from your meter’s menu the material type and material diameter
corresponding to your test material.
3. Before engaging the instrument onto the material, zero the instrument by
holding it in the same attitude you’ll be taking the readings, and pressing the
“Enter” or “Zero” button. This will eliminate any small tare effects.
4. Take readings along the material.
FOR BEST RESULTS ALWAYS TAKE SEVERAL READINGS OF
THE MATERIAL TENSION BYDISENGAGING AND THEN RE-
ENGAGING THE INSTRUMENT ON THE MATERIAL.
5. If the meter is accurately calibrated, readings will fall within 1% of the full-
scale capability of the instrument:
▪TX-125-1: +/- 1.3 grams
▪TX-1000-1: +/- 10 grams
▪TX-5000-1: +/- 50 grams
If you have additional questions, please contact Tensitron for assistance.

•Calibrate Instrument
*IMPORTANT: THIS FEATURE SHOULD ONLY BE USED BY A CALIBRATION FACILITY USING CERTIFIED AND
TRACEABLE DEAD WEIGHTS.DO NOT USE THIS FEATURE FOR A SIMPLE ACCURACY CHECK.
NOTE 1: TX-1 instruments are calibrated for Wire and Filaments through a
factory process not available to users. Use the calibration procedure below
to add or change a calibration in the CUSTOM menu.
NOTE 2: When calibrating your TX-1 instrument, tension values must be
entered in grams.
1. To add or change a calibration in the CUSTOM menu of your TX-1 meter,
first hang the material for the calibration as described in “General Calibration
Precautions” above. (You will suspend the weights later in the process.)
2. Access the setup menu: Turn on your meter and press the DOWN ARROW
until SETUP is highlighted, then press ENTER.
3. If there isn’t yet a CUSTOM NAME in the menu for the material, then add one
as follows:
oScroll down until CUSTOM NAMES is highlighted, and press ENTER.
oScroll down to CUSTOM1 (or to the next available CUSTOM entry),
and press ENTER.
oUsing a combination of the UP, DOWN and ENTER buttons, key in a
name for your custom material.
4. Add or change the calibration for your CUSTOM material:
oPress the ESCAPE button until only SETUP is showing, and press
ENTER.
oScroll down to RE-CAL TENSION, and press ENTER
oPress the ENTER, UP, ENTER buttons. (This is the password.)
oScroll up or down to select the CUSTOM NAME for the material want
to calibrate, and press ENTER.
oEnter the number of calibration points you will be using (at least five,
and no more than ten). Zero counts as the first point.
oENTER WEIGHT for each data point:
▪Zero is the first value and is already programmed.
▪Each successive data point should be a higher weight than
the previous one.
▪Data points are typically distributed evenly along the tension
range. (Example: With 5 data points for 1000 grams, use 0,
200, 400, 600 and 800.)
oWhen the display reads Zero Unit, hold the instrument (NOT engaged
on the material) in the attitude that you plan to do the calibration (likely
horizontal). Then, press ZERO.
oAs the display prompts you, suspend the correct weight from your
material. Then clamp the instrument on the material and press
ENTER.
oRepeat for each weight as prompted.
