CALIBRATION PROCESS FOR
MODELS PD 1201, PD 2501, DPT-1200, DPT-1200R, DPT-2500,
DPT-2500R AND PD 12003
6. Preliminary Instructions
a. The instructions outlined in paragraphs 6 and 7 are preparatory to the calibration
process. Personnel should become familiar with the entire bulletin before beginning the
calibration.
b. Items of equipment used in this procedure are referenced within the text by common
name as listed in table 2.
c. Unless otherwise specified, verify the result of each test and, whenever the test
requirement is not met, take corrective action before continuing with the calibration.
Adjustments required to calibrate the TI are included in this procedure. Additional
maintenance information is contained in the manufacturer's manual for this TI.
d. Unless otherwise specified, all controls and control settings refer to the TI.
7. Equipment Setup
a. Verify that TI is clean and free from defects that would impair its operation.
b. Ensure that the equipment has been allowed to stabilize at the ambient
temperature.
c. Position torque plate (mounting plate for PD 1201 and PD 2501) on a stable and
rigid work surface and secure with bolts or clamps.
d. Assemble TI and torque cell no. 1 (torque cell no. 2 for PD12003) on torque plate
(mounting plate for PD 1201 and PD 2501) using appropriate drive bar and socket wrench
adapter. Ensure that locating pins and drive bar are engaged in their respective mounting
holes. Install TI crank handle in socket as necessary.
e. Connect torque cell to force/torque indicator using cable supplied with force/torque
indicator. Connect force/torque indicator to appropriate power source. Turn power switch
to ON and allow the units to warm-up for 30 minutes. Select channel 3 using the
CHANNEL + and keys.
f. 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
and ccw torque. Ensure the serial number matches the torque cell being used.
