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 web from above and suspend known weights onto the web in
the values you’ve previously selected, when prompted. (See Figure 7.)
a. CALIBRATE TENSION, NUMBER OF POINTS __, ZERO UNIT.
Without any web 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 web that
you’ve
previously selected (In this example it would be 50 lb.)
c. Next, engage the instrument to your tensioned web, 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 web 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 web/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.
