h. Allow equipment to stabilize at ambient temperature.
i. TIs with range below 20 in-oz; connect low torque station to a 115 V ac power source.
Set power switch to ON and allow unit to warm-up for 30 minutes.
j. TIs with ranges of 20 in-oz to 12 in-lbs (192 in-oz); connect torque tester to a
115 V ac power source. Set power switch to ON and allow unit to warm-up for 30 minutes.
k. Perform l through q below for TIs with ranges of 12 in-lbs (192 in-oz) or greater.
l. Connect cable supplied with force/torque indicator to appropriate connector on
force/torque indicator and applicable torque cell.
m. Attach torque cell to holding fixture or torque adapter. Position torque cell with
cable hanging down at the six or seven o'clock position.
n. Connect force/torque indicator to a 115 V ac power source. Set power switch to ON
and allow unit to warm-up for 30 minutes. Select channel 3 by using the CHANNEL +
and keys.
o. Press the F4 key on the force/torque indicator until the
soft keys are
displayed. Press the
soft keys as necessary to select the torque cell for the TI
range, direction, and serial number being calibrated.
p. Press the F4 key on the force/torque indicator until the UNIT soft key is displayed.
Press the UNIT soft key as necessary to select the appropriate units to display.
NOTE
When possible use one torque cell to calibrate entire range of TI.
q. Exercise torque cell as described in (1) through (5) below:
(1) Attach socket wrench (part of adapter set) to torque cell.
(2) Slowly apply torque to torque cell in clockwise direction until full-scale is reached.
NOTE
The indicator will indicate + (positive) for clockwise torque and
- (negative) for counterclockwise torque.
(3) Slowly release torque until only tare torque of wrench is applied.
(4) Repeat (2) and (3) above two more times.
(5) Remove socket wrench from torque cell.
r. Exercise TI as described in (1) through (5) below:
(1) Attach TI to table mounted holding fixture.
