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, press POWER button. BAHCO 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).
Note: If wrench is powered up in torque only measurement mode, angle is not zeroed until mode is
changed to angle measurement mode, at which time torque and angle zeroing begins automatically
after 2 seconds. Wrench should be placed on a stable surface with no torque applied.
Note: Pressing ENTER button while angle is zeroing will abort zeroing function to allow user to
select another measurement mode.

TORQUE MODE

1. Set Target.
Use UP/DOWN buttons to change TORQUE target value.
2. Select Units of Measure.
Repeatedly press UNITS button while on target TORQUE screen until desired units are displayed.

½ second audible alert and handle vibration alerts you to stop.
4. Release TORQUE.
Note peak TORQUE reading flashing on LCD display for 5 seconds. Pressing BACKLIGHT button
while peak torque is flashing will continue to display value until button is released. Momentarily
pressing UP/DOWN, ENTER or UNITS button will immediately return to target TORQUE screen.
Reapplying TORQUE will immediately start another TORQUE measurement cycle.
5. Recall Peak TORQUE Reading.
To recall last peak TORQUE measurement, press and hold BACKLIGHT button for approximately 3
seconds. Peak TORQUE will flash for 5 seconds.
