(4) Press the TI indicator CHANNEL + and keys to select channel 1.
(5) Press the F4 key on the TI indicator until you see the
soft keys. Press
soft keys as necessary to select the load cell entry for the TI load cell and
the
direction being calibrated.
(6) Press the SIGNAL
keys to select the GROSS mode of operation.
Press the F4 key on the TI indicator until you see the Acal soft key. Press the Acal soft
key as necessary to activate the Acal enunciator.
(7) Press the F4 key on the TI indicator until you see the UNIT soft key. Press the
UNIT soft key as necessary to select lb to be displayed.
(8) Exercise TI load cell and standard load cell as described in (a) through (c) below:
CAUTION
Do not overload standard load cell or TI load cell.
(a) Apply force slowly to capacity of TI load cell.
(b) Release force slowly to obtain minimum indication on force/torque indicator.
(c) Repeat (a) and (b) above two more times.
(9) With no load applied press the F4 key on the TI indicator until you see →0←
soft key. Press the →0← soft key to zero force/torque indicator. Zero should be stable
within 0.02 percent of capacity. Zero the load cell indicator.

(10) Apply force to obtain a load cell indicator indication equivalent to approximately
10 percent of maximum range of TI load cell. If the TI indicator does not indicate within
Load Cell Accuracies listed in table 5 of load cell indicator reading then perform b below.
(11) Repeat (10) above for TI load cell cardinal points of 20, 40, 60, 80 and 100% of
full scale. Release force.
(12) Rotate TI load cell 120.
(13) Repeat (5) and (12) above for a total of three runs.
(12) Repeat (5) through (13) above for tension calibration.
(13) Repeat (5) through (13) above for all TI load cells.
b. Adjustments
NOTE
If necessary to update device setup, connect a serial cable
between the computer com port and the TI indicator com port
and use the MGCplus Assistant software to load the correct
device file for the size and direction of the TI load cell being
calibrated. Add the serial number to the device name.
