Caution!

Note the torque gauge’s capacity before use and ensure that the capacity is not exceeded.
Producing a torque greater than 150% of the gauge’s capacity can damage the internal sensor. An
overload can occur whether the gauge is powered on or off.

Typical materials able to be tested include many manufactured items, such as springs, electronic
components, fasteners, caps, mechanical assemblies, and many others. Items that should not be used
with the gauge include potentially flammable substances or products, items that can shatter in an unsafe
manner, and any other components that can present an exceedingly hazardous situation when acted
upon by a force.

The following safety checks and procedures should be performed before and during o peration:

1. Never operate the gauge if there is any visible damage to the AC adapter or the gauge itself.

2. Ensure that the gauge is kept away from water or any other electrically conductive liquids at all
times.

3. The gauge should be serviced by a trained technician only. AC power must be disconne cted and
the gauge must be powered off before the housing is opened.

4. Always consider the characteristics of the sample being tested before initiating a test. A risk
assessment should be carried out beforehand to ensure that all safety measures have been
addressed and implemented.

5. Wear eye and face protection when testing, especially when testing brittle samples that have the
potential to shatter under force. Be aware of the dangers posed by potential energy that can
accumulate in the sample during testing. Extra bodily protection should be worn if a destructive
failure of a test sample is possible.

6. In certain applications, such as the testing of brittle samples that can shatter, or other applications
that could lead to a hazardous situation, it is strongly recommended that a machine guarding
system be employed to protect the operator and others in the vicinity from shards or debris.

7. When the gauge is not in use, ensure that the power is turned off.

2 POWER

The TT03 is powered either by an 8.4V NiMH rechargeable battery or by an AC adapter. Since these
batteries are subject to self discharge, it may be necessary to recharge the unit after a prolonged period
of storage. Plug the accompanying charger into the AC outlet and insert the charger plug into the
receptacle on the gauge (refer to the illustration below). The battery will fully charge in approximately 8
hours.

USB connector

Power input jack

Caution!

Do not use chargers or batteries other than supplied or instrument damage may occur.

If the AC adapter is plugged in, an icon appears in the lower left corner of the display, as follows:
If the AC adapter is not plugged in, battery power drainage is denoted in a five-step process:

1. When battery life is greater than 75%, the following indicator is present:

2. When battery life is between 50% and 75%, the following indicator is present:

3. When battery life is between 25% and 50%, the following indicator is present:

4. When battery life is less than 25%, the following indicator is present:

5. When battery life drops to approximately 2%, the indicator from step 4 will be flashing.

Several minutes after (timing depends on usage and whether the backli ght is turned on or
off), a message will appear, “BATTERY VOLTAGE TOO LOW. POWERING OFF”. A 4-tone
audio indicator will sound and the gauge will power off.

The gauge can be configured to automatically power off following a period of inactivity. Refer to the Other
Settings section for details.

If battery replacement is necessary, the battery may be accessed by loosening the two captive screws in
the rear half of the housing and separating the two halves of the housing.

3 MECHANICAL SETUP

Fig. 3.1

Proper axial loading of Series TT03 torque gauge.

3.1 Proper alignment

Load must be applied axially with respect to the sensor, as shown in Figure 3.1. If attachments are used,
ensure that the sample is acted upon axially with respect to the instrument. Side loading or off-center
loading can damage the instrument, whether power is turned on or off.

3.2 Mounting to a plate
The indicator portion of the gauge can be mounted to a plate with four thumb screws fastened into the
appropriate holes in the rear half of the housing.

The torque sensor portion of the gauge (shown in Figure 3.1) can be mounted directly to a Mark-10
torque test stand or tabletop mounting kit without the need for any additional adapters. Flat surfaces are
provided to prevent rotation within a fixture.

Refer to the Dimensions section for detailed information.

The current displayed load reading. See Operating Modes section for
details.
Analog indicator to help identify when an overload condition is imminent. The
bar increases either to the right or to the left from the midpoint of the graph.
Increasing to the right indicates clockwise load, increasing to the left indicates
counter-clockwise load. If set points are enabled, triangular markers are
displayed for visual convenience. This indicator reflects the actual load, which
may not correspond to the primary reading (depends on operating mode).
The ZERO key does not reset the load bar. See Operating Modes section for
details.

lbFin – Pound-inch
ozFin – Ounce-inch
kgFmm – Kilogram-millimeter
Ncm – Newton-centimeter
Note: not all sensor models display all the above units. Refer to the capacity /
