Wrench Power On Sequence
Note: Do not turn on wrench while torque is applied, otherwise torque zero offset will be incorrect and
wrench will indicate a torque reading when torque is released. If this occurs, re-zero wrench by
momentarily pressing POWER button while wrench is on a stable surface with no torque applied.
1. Turn On Wrench.
While holding wrench still, momentarily press POWER button. Snap-on logo will be displayed
followed by torque and angle re-zeroing screens (if angle mode has been previously
selected). If real-time-clock has not been set, date and time entry screens are displayed (see
Advanced Configuration section for entering date and time). After entering date and time or
if time has been previously set, target TORQUE or ANGLE screen will now be displayed
depending on previous measurement mode selected.
2. Select Measurement Mode.
Toggle between target TORQUE and ANGLE screens by repeatedly pressing ENTER button.
Note: When date and time is set for first time, In-Service date is also set and is used for calculating
initial calibration interval (see "Setting Calibration Interval" in Advanced Configuration section).

torque or angle reached. Second

Third indicates 80% of target
reached.
Green - Indicates target torque or angle
reached.
Red - Indicates exceeded torque or
angle target plus 4% or exceeded
