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:
o
Scroll down until CUSTOM NAMES is highlighted, and press ENTER.
o
Scroll down to CUSTOM1 (or to the next available CUSTOM entry),
and press ENTER.
o
Using 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:
o
Press the ESCAPE button until only SETUP is showing, and press
ENTER.
o
Scroll down to RE-CAL TENSION, and press ENTER
o
Press the ENTER, UP, ENTER buttons. (This is the password.)
o
Scroll up or down to select the CUSTOM NAME for the material want
to calibrate, and press ENTER.
o
Enter the number of calibration points you will be using (at least five,
and no more than ten). Zero counts as the first point.
o
ENTER 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.)
o
When 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.
o
As the display prompts you, suspend the correct weight from your
material. Then clamp the instrument on the material and press
ENTER.
o
Repeat for each weight as prompted.
