• Read this manual completely
before using ELECTRONIC
TOOL.
• To insure accuracy, work must
not move in angle mode.
• For personal safety and to
avoid tool damage, follow good
professional tool and fastener
installation practices.
• Periodic recalibration is
necessary to maintain
accuracy.
• Wear safety goggles, user and
bystanders.
• Be sure all components,
including all adaptors,
extensions, drivers and
sockets are rated to match or
exceed torque being applied.
• Observe all equipment, system
and manufacturer’s warnings,
cautions and procedures when
using this tool.
• Use correct size socket for
fastener.
• Do not use sockets showing
wear or cracks.
• Replace fasteners with
rounded corners.
• To avoid damaging tool: Never
use tool with power off. Always
turn ON tool so applied torque
is being measured.
• Do not press POWER while

This equipment has been tested and found to comply with the limits for a Class B digital device, pursu-
ant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against harmful interference in a residen-
tial installation.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equip-
ment does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
• Consult the dealer or an experienced radio/TV technician for help.
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to
the following two conditions:
(1) This device may not cause interference, and
(2) This device must accept any interference, including interference that may cause undesired opera-
tion of the device.

Note: Do not turn on tool while torque is applied, otherwise torque zero offset will be incorrect
and tool will indicate a torque reading when torque is released. If this occurs, re-zero tool by
momentarily pressing POWER button while tool is on a stable surface with no torque applied.

screen will now be displayed (depending on previous measurement mode selected).
Note: By simultaneously pressing the ENTER and UNITS U buttons, the keypad can be locked
to prevent inadvertent button presses while griping the screwdriver body. The Lock Icon is
displayed when the keypad is locked. To unlock the keypad, press the ENTER – UNITS U –
ENTER buttons in sequence (on screwdrivers (SCR) only).
Note: If the keypad was locked when powered down, on power up, the keypad will remain
locked and will require the keypad unlock button sequence of ENTER – UNITS U – ENTER to
become functional again (on screwdrivers (SCR) only).

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: If screwdriver is powered up in torque only measurement mode, angle is not zeroed until
keypad is unlocked and mode is changed to angle measurement mode. The Angle Zero Required
screen will be displayed. Angle zeroing begins automatically after 2 seconds. Screwdriver should
be placed on a stable surface with no torque applied (on screwdrivers (SCR) only).
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.
