CALIBRATION

To properly calibrate the CTA, application of a precise torque value equal to the

full capacity of the tester in pound-inches (regardless of the displayed units) is

required.

While holding PEAK, turn on power to the tester. When ‘CAL’ appears on the

display, press ENTER three times to select the calibration mode. At the ‘null’

prompt, press ZERO. At the ‘SPAn’ prompt, apply the calibration torque and

press ENTER. The display will show ‘uuuu’ or ‘nnnn’ if the calibration torque is

insufficient or excessive, respectively. If this happens, the only way to terminate

the calibration mode is by momentarily disconnecting the battery or connecting

the AC adapter to the tester without plugging the other end into a wall outlet.

This will stop the calibration procedure without making any changes to the pre-

vious calibration data.

Successful calibration is indicated by ‘donE’ on the display. Press ENTER to

save the changes and resume normal operation.
