In a Breakaway test, torque is applied to fastener that
is already tightened. When enough torque is applied and the
fastener begins to turn or breakaway, the test stops.
In a
Yield test, torque is applied to a fastener until the screw
or base material thread begins to deform, then the test
stops. |
Torque controlled power tools are set to apply consistent torque,
but fasteners are not necessarily tightened to that value. Breakaway
torque tests are used to measure the actual tightening torque of the
fastener.DI-12 Motorized Torque Tester measures breakaway torque
automatically without overtorquing already tightened fasteners. Once
breakaway torque is determined, powertools can be reset to the
proper tightening torque. DI-12 also detects the yield torque value
of untightened fasteners. Proper tightening torque can be determined
as a percentage of yield torque value. DI-12 features selectable
units (lbf-in, kgf-cm and N-m), and Peak, Real Time or
Breakaway/Yield measuring modes. Torque data can be continuously
output to data acquisition software via RS-232, enabling you to
display torque profiles of breakaway and yield torque.

Operation
|
Both CW and CCW motorized rotation
|
Measurement modes
|
P-P: Displays PEAK Torque value that will not change
until a higher value is measured.
T-R: Displays TRANSIENT torque values.
RG: Determines peak down and yield torque (CW only)
If a peak down torque value is detected, the green indicator
will light, and tester rotation will stop automatically.

Test Start Value
|
Start of RG Mode can be set in 0.001 N-m increments.

RS-232 Output
|
Continuous (9600 baud) output in PP and RG measuring
modes.
|
Auto-power-off
|
After 5 minutes of non-use.
