3. Function / signal levels

• The torque wrench with built-in angle gauge has four signal levels (combined visual, audible and physical signals) that are activated when configured values are reached.
• The visible signals are shown below the matted ring on the handle, the audible signals are generated by a buzzer in the housing and the physical signals are created by a vibration motor in the handle.
• The torque wrench with built-in angle gauge has two selectable operating modes: "Torque" and "Rotation angle".
• In "Torque" mode, you can select the torque programs "Torque track" and "Torque peak".

• A snug torque (starting point for the angle measurement), a target value for the rotation angle and a ± tolerance for the rotation angle in "0" (degrees) are entered in the "Rotation angle" program.

• A yellow light flashes once upon reaching the snug torque and therefore the start of angle measurement.

• The first signal level – yellow flashing light, acoustic signal and low-frequency vibration – starts when the applied torque reaches the set threshold value, e.g. 80% of the lower value of the target value range. Once the first signal level is reached, you should reduce the tightening speed and pay closer attention to the force you are applying, the display and the signals of the torque wrench with built-in angle gauge. The lower the target value and the higher the threshold, the quicker the first signal level is exceeded.
• The second signal level – green flashing light, acoustic signal and mid-frequency vibration – indicates that the applied torque is within the target value range. Once the second signal level is reached, stop screw action in this area.

The lower the target value and the tolerance value, the quicker the second signal level is exceeded.

• The third signal level – red flashing light, acoustic signal and high-frequency vibration – indicates that the applied torque is above the target value range. If the third signal level is reached, the applied torque is too high. Stop the screw action. Proceed in line with the instructions for this screw-joint: e.g. undo the screw and re-tighten it, or replace it with a new one.
• The fourth signal level – permanent red light, permanent acoustic signal and permanent vibration – indicates that the applied torque is above the maximum permissible torque range of the torque wrench with built-in angle gauge. If the fourth signal level is reached, the screw action must be aborted immediately. Failure to comply with these instructions can result in (irreparable) damage to the torque wrench with built-in angle gauge.
• If no further torque or rotation angle is applied after activation, the display alternates between the maximum value of this action and an OK/Not OK message.
• The "Torque track" program displays the torque currently being applied without specification of a target value or a tolerance on the display. In this program, only the fourth signal level is activated when the maximum permitted torque value has been reached. The highest torque value for this process (without validation) is displayed when no more force is being applied.
• The torque wrench with built-in angle gauge can be programmed with "Direction of rotation: right (+)" and "Direction of rotation: left (-)" in the "Torque peak" and "Rotation angle" programs.

NOTE! In "Torque track" and "Peak" mode, the screw action stops after 2 seconds if no torque is applied during this time. In "Rotation angle" mode, the screw action stops after 4 seconds if no torque is applied during this time.

• Every screw action is stored in the memory with a corresponding date and time.
• Pressing a key rotates the display (in order to read the display regardless of direction of actuation).
• The torque wrench with built-in angle gauge switches off automatically after the set "stand-by" time when it is not being used.
• If necessary, a rotation angle check for torque tightening and a torque check for rotation angle tightening can be programmed in order to check the screw action and connection. If a check function is programmed, the second signal level is only activated and the screw action is only evaluated as OK if the relevant target value and check ranges overlap with one another at the end of operation.
• The "Parameters" menu option allows you to save programs for various screw-joints. Activating a workflow enables these screw-joints (parameters) to be completed one after another. The wrench display indicates the progress of the workflow.

6. Before starting the operation

Always ensure tools are used, inspected and maintained in compliance with the respective local, state, national or federal regulations.

To prevent failures in the transfer of force, do not use hinge connections or extensions where possible. The torque applied to the screw joint can be changed dramatically when using hinge connections.

Ensure that the insert tool holder, socket wrench inserts or other accessories in use are seated firmly. When using reversible ratchets, check the required direction of the rotation setting. The lever at the top of the insert reversible ratchet switches the ratchet between clockwise and anti-clockwise operation.

When using inserts, ensure that their design conforms to stand - ards and that their shape and size are correct for screw joint connection. You should also ensure compliance with the maximum permitted load for the insert in use. This can be lower than the achievable torque for the torque wrench with built-in angle gauge. Modified or custom-made tools can be dangerous and may not be used. Do not use worn or damaged tools or inserts. Failure to comply can result in personal injury and/or material damage.

Position the tool so that it cannot slip from the screw joint. Users must maintain a safe, balanced position when working. Failure to do so poses a hazard to persons and/or a risk of material damage.

It is possible for screw joints to become loose. Do not exceed the maximum torque of the torque wrench with built-in angle gauge (such as when undoing bolts which are seized due to rust) under any circumstances. Overloading may damage the torque wrench with built-in angle gauge and falsify the release value.

When tightening the rotation angle, ensure that the expected torque for the set rotation angle does not exceed the maximum permitted torque for the tool.

8.1.1 Track

NOTE! The "Torque track" program displays the torque currently being applied without specification of a target value or a tolerance on the display. In this program, only the fourth signal level is activated when the maximum

permitted torque value has been reached. The highest torque value for this process (without validation) and the direction of rotation (leading sign + = right, - = left) are displayed when no more force is being applied.

NOTE! The "Track" mode is suitable for determining the breakaway torque of tightened screws, for example.

8.1.2 Peak

1. After pressing OK, selecting the "Peak" menu option enables you to set the values for torque "Target value" using ↑↓.
2. After confirming this value with OK, you can set the direction of rotation to right (+) or left (-) using ↑ ↓. The direction of rotation selected is shown with a yellow background.
3. After confirming the direction of rotation with OK, you can set the permitted ± tolerance in percent (%) for the target value of the torque using ↑ ↓. A target value range is defined by entering a target value and the permitted tolerance range. For example, the target value range for a target value of 100 Nm with a tolerance of ±4% is between 96 Nm and 104 Nm. In addition to the numerical values on the display, the signals of the torque wrench with built-in angle gauge inform the user of the torque being applied.
4. Confirming the tolerance value with OK displays the "Rotation angle check" menu option. Pressing OK again enables you to select whether the target torque value is to lie within a certain angle range or not using ↑ ↓.
5. If you do not want to perform a rotation angle check and select "No", you will return to the menu after pressing OK.
6. If you wish to perform a rotation angle check and select "Yes", you can press OK and then use ↑ ↓ to set the value for the snug torque.
7. After confirming the value for the snug torque with OK, you can set the lower rotation angle value of the check range with ↑ ↓.
8. After confirming the lower rotation angle value with OK, you can use ↑↓ to set the upper rotation angle value of the check range.
9. Confirm the upper rotation angle value with OK.

8.2 Rotation angle

The "Rotation angle" menu option enables you to carry out the programming for the tightening method "Rotation angle".

1. After pressing OK in the "Rotation angle" menu option, you can set the value for the snug torque with ↑↓.
2. After confirming the value with OK, you can set the value for the rotation angle with ↑ ↓.
3. After confirming this value with OK, you can set the direction of rotation to right (+) or left (-) using ↑ ↓. The direction of rotation selected is shown with a yellow background.
4. After confirming the direction of rotation with OK, you can set the permitted ± tolerance in degrees (°) for the rotation angle using ↑ ↓.

NOTE! The ± tolerance in degrees (°) can be set in 1° increments from 1° up to max. 10% of the rounded-down rotation angle value.

Example: Rotation angle 98^ = . tolerance 9^

If, for example, a rotation angle of 75^ is set in a new program, the tolerance is automatically set at ±7^ . The tolerance can then be changed from ±7^ in 1^ increments to ±1^ .

NOTE! If the wrench in "Rotation angle" mode is activated, the first value (before the slash) is the displayed rotation angle and the second value (after the slash) is the torque applied here.

Initially the value after the slash (torque) is displayed on its own - until the snug torque is reached - and then the value before the slash (rotation angle) appears after the yellow signal.

1. Confirming the tolerance value with OK displays the "Torque check" menu option. Pressing OK again enables you to select whether the rotation angle to be tightened is to lie within a certain torque range or not using ↑ ↓.
2. If you do not want to perform a torque check and select "No", you will return to the menu after pressing OK.
3. If you wish to perform a torque check and select "Yes", you can press OK and then set the lower torque value of the check range with ↑ ↓.
4. After confirming the lower torque value with OK, you can use ↑ ↓ to set the upper torque value of the check range.
5. Confirm the upper rotation torque value with OK. This concludes programming.

Activating a workflow enables these screw-joints to be completed one after another. The activated workflow, the current position in the workflow and which parameter can be processed next appear on the wrench display. The corresponding parameters must first be programmed in the menu item "Parameters" in order to insert them into the workflow. Up to 25 different screw joints can be stored.

Programming parameters

1. You must switch to the menu with M and select the "Parameters" menu option with ↑ to program parameters.
2. After pressing OK in the "Parameters" menu option, you can select the required parameter – from "Parameter 1" to "Parameter 25" – with ↓. Use ↑ to go backwards within the parameter selection.
3. Confirming the parameter selected with OK displays "Inactive" / "Active".

NOTE! If the "Inactive" display has a yellow background, this parameter is not currently being used in a workflow. If the "Active" display has a yellow background, this parameter is being used in at least one workflow. Check carefully whether you really want to change this parameter because the change becomes effective when a workflow containing this parameter is activated.

1. If you want to change the parameter, press OK to display "Torque" / "Rotation angle". Here you can use ↑ ↓ to select the mode in which this parameter should be programmed. The mode selected is shown with a yellow background.

8.10. Application / operation of the torque wrench with built-in angle gauge

The torque wrench with built-in angle gauge must only be operated with the handle at right angles to the screw joint. The hand force deployed must be applied uniformly onto the centre of the handle (ring marking).

In order to avoid measurement errors when measuring the rotation angle, do not allow the screwed workpiece or its support to turn, move or sway during operation.

You can also activate the dimmed display to reduce the power consumption.

After approx. 30 seconds the display is dimmed slightly.

8.11 PC connection

The torque wrench with built-in angle gauge is ready to be connected to the optionally available Smart Tool software. The subsequent procedures for establishing a connection, reading saved data and for programming the wrench with the software are part of the operating instructions for the SmartTAC Tool software.

9. Adjustment / calibration

Electronic torque wrenches with built-in angle gauge should be checked and calibrated on a regular basis. After a long period of use, re-certification or re-calibration by the factory is advisable. Electronic torque wrenches with built-in angle gauge are measuring tools. Appropriate measurement equipment must be used to test (and where applicable, adjust) measuring tools at the time intervals laid down by Quality Management.

The time gap between test dates is dependent on the frequency of use. We recommend testing after approx. 5000 screw operations (but the period in-between tests should be no longer than 6 months).

NOTE! The "Version" menu option provides information on the software version, the serial number, the date of the last calibration and the remaining number of releases until the next calibration of the wrench.

1. To access the information in the "Version" menu option, you must switch to the menu with M and select the "Version" menu option with ↑.
2. The software version information is displayed after pressing OK in the "Version" menu option.
3. Further information is shown on the second page of the display. Use ↓ to move to the 2nd screen and ↑ to return to the 1st.

HAZET has appropriate test equipment. HAZET torque wrenches with built-in angle gauge sent in to HAZET are returned with a test certificate after they are checked and after any necessary adjustment/calibration work is carried out. The test equipment used by HAZET for torque wrenches with built-in angle gauge is continually monitored by the German Calibration Service (DKD) and is calibrated and adjusted whenever required. This guarantees both the level of expertise necessary in the field of controlled screw joint tightening and also the quality of HAZET tools.

The HAZET factory also accepts electronic torque wrenches with built-in angle gauge from your specialist dealer for inspection and calibration.

10. Torque wrench with built-in angle gauge certificate and calibration instructions

Every torque wrench with built-in angle gauge comes with a calibration certificate in compliance with DIN EN ISO 6789-2:2017 and VDI/VDE 2648 part 2.
