The WrenchStar Multi is a wireless production and quality audit wrench which works with the IQVu or TCI.
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 and the 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 such as Peak. The WrenchStar Multi communicates the final fastening readings to an IQVu
using RF giving a range of approximately 10m
*
. If the WrenchStar Multi loses its link to the IQVu, then it
continues to work offline, storing up to 200 readings. It is very easy to pair, (associate the connection), of a
WrenchStar Multi with a particular 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

The WrenchStar Multi unit has a battery pack that contains a Lithium Ion battery. From fully discharged the
unit will require up to a 4 hour charge to attain maximum capacity.
The full capacity of the battery is 2600mAh which yields approx. 10 hours of normal use.
When a WrenchStar Multi is placed in charging cradle, the charge indicator LED will illuminate with colour
according to the charge status.

The wrench can be charged by inserting into the charging cradle.
Note: alternative charging methods may become available in the future.
The WrenchStar Multi will monitor its battery level. If the battery level goes below 10% the status LED will
flash blue. If the status LED starts flashing it is recommended that the readings are immediately finished and
the WrenchStar Multi taken back to the IQVu to upload any remaining readings. The WrenchStar Multi
should be fully charged in a cradle before using. If the level goes to 0% the WrenchStar Multi will switch
OFF.
Charger voltage is 5V.
The WrenchStar Multi button has several functions:
•When the WrenchStar Multi is OFF pressing the button for less than 1s will turn the WrenchStar
Multi ON.
•When the WrenchStar Multi is ON and the button is pressed for approx. 2s the WrenchStar Multi will
go into pairing mode and the status LED will change to purple.
•If the WrenchStar Multi is in pairing mode pressing the button will take the WrenchStar Multi back to
normal RF mode and the status LED will change to blue.
•If the WrenchStar Multi is ON and the button is held for more than 5s then the WrenchStar Multi will
switch OFF.
The WrenchStar Multi will switch OFF after 10 minutes of no activity. It can be turned back ON with a press
of the button. No activity means no torque messages from the IQVu and no torque pulled.

•Amber = LO
•Green = OK
•Red = HI
If the secondary parameter goes HI then light ring will go Red regardless of state of the primary

If MoveOn or Yield are not detected and torque was LO or OK then will get amber flash sequence
(dash dot dot), otherwise if torque was HI then will get red flash sequence (dash dot dot).
The light ring will start indicating the status as soon as torque goes above threshold.
When a new job is received the light ring will cycle twice through sequence amber, green, red to
indicate job has been received and loaded. It will do the same when power up and the job is already
loaded.
When a job is complete the light ring will continuously cycle through sequence amber, green, red
until data is completely removed.
•The WrenchStar Multi will work with the Crane 1-Touch ID Head recognition system, the Crane 1-
Touch system allows the wrench to compensate for special head designs that do not use the
standard insert head dimensions.
•The Crane 1-Touch Heads can be programmed with an ID from 1 through to 126, if there is no ID
then the WrenchStar Multi will not use the ID system and treat the head as a standard insert head,
with a critical compensation length of Zero.
•The 1-Touch ID heads can be programmed with a compensation length, these lengths can be from 0
to 200 mm. When the wrench recognises that there is an ID Head present, it will automatically
compensate the torque by the critical length programmed into the head.
•The 1-Touch ID Heads can be programmed up to 4 times, therefore if the compensation value needs
to be updated, this can be done up to 3 times. This programming is done by Crane Electronics.
•Below is a diagram of how to calculate the critical length for an ID Head.

Yellow (amber) =Threshold < Value < LSL
Green = LSL < Value < USL
Red (user should stop pulling if they see Red) = USL < Value
If the Secondary value goes greater than its USL you will see a Red light on the WrenchStar Multi to warn
the user to stop.
At the end of a measurement, until the next measurement starts, the WrenchStar Multi will display the
primary measurement status for that joint.
In the case of a MoveOn or Yield not being found the Light Ring will flash (long flash followed by 2 short
flashes) amber if the torque reading remains below the USL and flash red if the final torque reading is above
the USL.
The WrenchStar Multi is constantly being polled by the IQVu for readings (every 0.5s). If the WrenchStar
Multi goes out of range it can continue to take readings, which it will store. Once the WrenchStar Multi is in
range of IQVu, the readings will be polled out of the WrenchStar Multi, oldest first.
If the WrenchStar Multi completes the subgroup of the job it will flash amber, green then red twice. When
this happens you should take the WrenchStar Multi back to the IQVu so any remaining readings can be
uploaded. If required, you can then download the next subgroup.
IQVu check is assumed to be a job subgroup with 200 readings.
The IQVu will show the readings it gathers from the WrenchStar Multi in the standard way. The readings will
have their status colour coded as usual. The reading count will show how many readings have been
retrieved.
Note: - no traces are stored or can be retrieved from the WrenchStar Multi.
The following screens show examples of readings gathered by IQVu from the WrenchStar Multi using
different measurement modes:
