The WrenchStar Multi is a wireless production Wrench with audit capability when connected to the
IQVu or Tool Control Interface (TCI) lineside controller. There is a variant that works with a cable
connected to the IQVu. In this case there is no battery pack or RF. The power comes from the IQVu.
Torque and Angle data are transmitted as digital signals along the cable to the IQVu.
The WrenchStar Multi reads the Torque and Angle values in real time and converts them to digital
values. The WrenchStar Multi analyses the digital samples using measurement algorithms to
calculate properties of the fastening. The WrenchStar Multi communicates the final fastening
readings to an IQVu using RF giving a range of approximately 10 metres*. If the WrenchStar Multi
loses its link to the IQVu, then it continues to work offline, storing up to 200 readings. It is simple to
pair a WrenchStar Multi with an IQVu.
The WrenchStar Multi contains its own power source which is a Lithium Ion battery pack.
* The RF range depends on the environment in which the WrenchStar Multi and IQVu are being used
and the figure quoted is for a relatively metal free work space with the IQVu in line of sight of the
WrenchStar Multi.
Physical Measurement:
Bi-directional torque and angle. Pulse count.
Measurement Modes:
Peak: Capture of highest Torque value during the cycle.
MoveOn: Capture of MoveOn point Torque during auditing of a tightened joint.
Yield: Special measurement algorithm for use with joints being taken into plastic region.
The Wrench supplies its torque range (span), PPR (for Angle), serial number, calibration due date.
Reading Storage:
The WrenchStar Multi can store up to 200 readings in Offline Mode.
LEDs:
The WrenchStar Multi has a:
Charge LED used when charging battery pack. Status LED
Light Ring for fastening status.
Torque Measurement:
Resolution to 0.006% of transducer span
Sampled every 60 micro-seconds (16,667) per second
