CALIBRATION

General Information

This section describes the calibration method for the torque/angle sensors. Calibration is accomplished by performing tightenings with the wrench and referencing external measuring equipment to compare the results. The Parameter Adjustment Knob on the wrench's front panel is used to match the wrench display readings to that of the reference equipment. Calibration values are stored in nonvolatile memory. Any previously entered setup parameters already stored in tightening modes are scaled to reflect the altered calibration. Performing calibration causes all final tightening data and stored curves to be flushed from memory. Calibration requires torque instrumentation certified to national standards at 0.1% of torque. Currently angle measurements are not traceable to a national standard.

When calibration is complete, rotate the Mode Select switch back to the setup position. Press the Reset button and rotate the Parameter Adjustment Knob CCW until the Custom Setup Mode number is below 100. This is necessary to activate the Timeout feature. Update records or label with new calibration information and data.

NOTE

If calibration equipment is not available, it is recommended that the wrench be returned to an authorized Ingersoll-Rand service center for an annual recalibration.

NOTE

If the wrench has an angle reference arm (models EA-), calibrate angle before calibrating torque. If the wrench has an EZ angle non-contact angle sensor (models EVS-), calibrate torque before calibrating angle.
