l. Press the F4 key on the TI indicator until you see →0← soft key. Press the →0←
soft key to zero force/torque indicator.
m.
Exercise system in
direction of
intended calibration. Apply full
load to
system, using
appropriate weights from weight sets. Decrease load slowly and carefully, hesitating about
30 seconds at full and no-load positions. Repeat the cycle twice.
NOTE
System should be exercised by loading to full load in the proper
direction just prior to calibration.
CAUTION
Do not exceed rated capacity of TI.
NOTE
Readings are + (plus) in cw direction and - (minus) in ccw.
a. Performance Check
(1) Press the F4 key on the TI indicator until you see →0← soft key. Press the
→0← soft key to zero force/torque indicator.
NOTE
Calibration data on TI should be taken within 30 minutes after
exercising.
NOTE
Apply torque smoothly in the increasing torque direction.
obtain torque in cw direction for each calibration point listed in table 3. Remove weights.
If TI indication is not within tolerances listed in table 3 then perform b below.
NOTE
Deenergize TI indicator before changing torque cells.
(3) Repeat 7f through 8a(2) above for all torque cells in both cw and ccw directions.
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 torque cell being
calibrated. Add the serial number to the device name.
