Specification

Special Features
Patented mechanism for reliable measurement of impulse tools. Integrated light ring giving visual indication of fastening status.

Tool Compatibility
All torque tools, including impulse tools (not impact tools). Joint kit recommended for off-line measurement of continuous drive and impulse tools to represent joint conditions.

Physical Measurements
Bi-directional torque (clockwise calibration unless otherwise specified) . Optional bi-directional angle encoder (also enables RPM measurement on suitable indicator).

Plug and Play Transducer
A Crane readout or data collector can automatically read the following information from the CheckStar Multi transducer. Torque range, angle encoder data, serial number, calibration due date.

Calibration
Issued with calibration certificate traceable to National and International Standards.

Standard Crane Calibration
10 points; single direction (clockwise unless otherwise requested); 10% to 100% of nominal torque. Recalibration is recommended every 12 months.

Bi direction Standard Calibration
(optional) 10 points; each direction; from 10% to 100% of nominal torque.

UKAS Calibration
Calibration to BS 7882.

Construction
Patented slip ring mechanism eliminating signal losses due to brush bounce and enabling low running friction in either direction (<0.1% rated torque or 0.1Nm, whichever is greater); design is durability tested to >100 million revolutions with no measurable degradation of electrical performance or wear.
