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 "°" (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.

nal 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.22

Design and function Signals table Signal levelsTorqueRotation anglePeak TrackLevel 1 (threshold value) Yellow flashing light, acoustic signal and low-frequency vibration v v Level 2 (within target value range) Green flashing light, acoustic signal and mid-frequency vibration v v Level 3 (above target value range) Red flashing light, acoustic signal and high-frequency vibration v v Level 4 (above max. torque) Permanent red light, permanent acoustic signal and permanent vibration v v v Yellow light flashes once on reaching the snug torque start of angle measurement

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 activa

tion, 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 pro

gramed 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 dur

ing 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 cor

responding 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 con

nection. If a check function is programed, 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.

6. Before starting the operation

Always ensure tools are used, inspected and main- tained 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 con- nection. 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.

Design and function 8.10. Application / operation of the torque wrench with built-in angle gauge The torque wrench with built-in angle gauge must only be oper- ated 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.

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 measur

ing 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 opera

tions (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.

ment/calibration work is carried out. The test equipment used by HAZET for torque wrenches with built-in angle gauge is continu

ally 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.

(3 sec. until acoustic signal sounds twice), the torque wrench with built-in angle gauge is defective. Send the torque wrench with built-in angle gauge to your HAZET partner for testing. "System test not OK" An electronic system test runs at power-on. If the torque wrench with built-in angle gauge is under load when switched on, the message "System test not OK" is displayed. Switch the torque wrench with built-in angle gauge off by pressing . Place the torque wrench with built-in angle gauge on a flat, stable surface such that no loading is applied to it. To switch on the torque wrench with built-in angle gauge, re-press

(3 sec. until acoustic signal sounds twice). "System test not OK" If it is certain that the torque wrench with built-in angle gauge was not under any load when switched on, and "System test not OK" is displayed nevertheless, the torque sensors are not working properly (e.g. fol

lowing overloading). Send the torque wrench with built-in angle gauge to your HAZET partner for testing. "Service" If "Service" is displayed after switching on the torque wrench with built-in angle gauge, this is an indication that 5000 load cycles have been performed since the last calibration. If you wish to ignore this message, press

and at the same time. Work can continue immediately. This message continues to be displayed every time the device is switched on. Send the torque wrench with built-in angle gauge to your HAZET partner for calibration. The direction of rotation, the torque target value and the tolerance specification (in %) are not displayed when swit

ched on. You are in mode "Track torque" You are able to work in program "Track torque". You are able to change the torque program. Refer to

No value is displayed upon operating the torque/angle wrench. You are on the start display. "OK" is dis

played. Check the settings carefully. Confirm the settings by pressing . "OK" is no longer displayed. The torque wrench with built-in angle gauge is ready to use. Torque or rotation angle value not OK (alternately) The torque or rotation angle value applied was not within the programed tolerance of the target value. The torque or rotation angle value was too low. No, or only the first, signal level was activated during operation. 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. Carefully increase the torque. Pay attention to the actu

ation speed and the signal levels. Operate the torque wrench with built-in angle gauge in such a way that it remains in the 2nd signal level. Torque or rotation angle value not OK (alternately) The torque or rotation angle value applied was not within the programed tolerance of the target value. The torque or rotation angle value was too high. The 3rd or 4th signal level was activated during operation. 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. Reduce the actuating force. Pay attention to the actu

ation speed and the signal levels. Operate the torque wrench with built-in angle gauge in such a way that it remains in the 2nd signal level.32

Message Reason Action The 4th signal level with per- manent red light, permanent acoustic signal and permanent vibration is activated. "Overload error" appears. The torque applied was above the maximum permitted 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.

Batteries flat The rechargeable battery is discharged. Stop using the torque wrench with built-in angle gauge. Replace or charge the rechargeable battery. See Section 7, "Commissioning" The rotation angle measure

ment / display does not conti- nue to increase during operati- on and/or drops briefly. The snug torque was exceeded at the start of the thread and/or operation, which activa- ted the rotation angle measurement. Further rotation will bring the torque below the previ- ously reached snug torque. This can happen if the thread is damaged or soiled. 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. If necessary, clean and/or re-cut the thread. The rotation angle is not mea

sured and/or displayed. The screw is already so firmly tightened that it will no longer rotate. This can happen if the screw has been inserted, for example, with an impact wrench. 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.33
