minimum of 4 increasing tension values such as: 50, 100, 150 and 200. If
desired you can define more than 5 weight points, with a maximum of 10
points total. If 10 calibration points were selected the entries could look
something like this: 10, 20, 30, 40, 50, 60, 70, 80, 90.
5.
ENTER WEIGHT . After selecting the number of calibration points, you
need to define these weight values. Using the up or down arrows select
your first tension or weight calibration point and press
ENTER. Do not use
0 (zero) as this value is already programmed into the instrument . Next, use
the up or down arrows to select your weight 2 value, making sure the
value entered is greater than the entry in weight 1 . Next, select increasing
weight values for the additional weight points, without exceeding the
maximum tension range of the instrument.
6.
CALIBRATE TENSION . Next you will calibrate the instrument using the
weight values you previously selected. To properly simulate these
tensions, suspend a single length of your material from above and
suspend known weights onto the material
in the values you’ve previously
selected, when prompted. (See Figure 8.)
a. CALIBRATE TENSION, NUMBER OF POINTS __, ZERO UNIT.
Without any material engaged to the instrument, hold it in the
attitude you will be taking the reading in and press ENTER to
calibrate zero weight. Next the display will prompt you to
suspend the weight value you previously selected in step 5. If,
for example you selected 50 lb. for your first weight value the
instrument will indicate: PLACE WEIGHT 50.
b. Suspend the exact weight value from your material that
you’ve
previously selected (In this example it would be 50 lb.)
c. Next, engage the instrument to your tensioned material, then
press ENTER once the reading has stabilized.
d. Repeat steps b. and c. for the remaining weight points by
suspending additional weights onto your material in the values
previously selected and entering these readings.
e. Once the last weight value is entered, the instrument will return
to the SETUP menu. Press the ESCAPE button to return to the
main display.
f. The main display will now indicate the material/material
description you just finished calibrating. If the material name on
the display is not the material you just recalibrated, you have re-
programmed the incorrect description. If this happens, you will
need to recalibrate both the material indicated on the display
along with the material you thought you were calibrating.
g. After completing a calibration always recheck the values. Refer
to “Check Accuracy” in Section 7
