1. Program start

Start the software by double-clicking on the link.

First select the language using the selection function (GERMAN / ENGLISH).

2. Master data

First, update the master data and create manufacturers, manage users and configure the filing of the test certificates. These steps are described further in the following and in the Software chapter.

Note: HAZET is pre-set as the manufacturer and corresponding test objects (torque wrenches) are stored with their parameters and technical data.

Do not reach into the device during operation!

Changing the user

Hinweis: An admin and a tester are pre-set.

User: Admin

Password: Admin

User: Tester
Password: Tester

You have the option of creating new users. The corresponding steps are explained in the Software User Administration and User Authorization chapter (page 27)

Note: Only a created admin has permissions to change or create test parameters and master data. The tester can only carry out the test or calibration with the corresponding menu structure.

Changing the manufacturer

You have the option of creating new manufacturers. The corresponding steps are explained in the Software Manufacturers chapter (page 19)

3. Configuration:

In the Configuration tab you have the option of placing your manufacturer logo in the test certificate. To do this, store your logo in the displayed file path to use it in the output documents.

Furthermore, it is possible to bring the HAZET calibration unit into the initial position (The initial position is comparable to a zero position).

Caution: before you bring the HAZET calibration unit to the initial position you must remove the test object!

Do not reach into the device during operation!

⑤ Measurement / Calibration

NOTE!

When a torque wrench is calibrated for the first time, the initial test may take longer than the subsequent tests. This has to do with a speed control that is "learning".

NOTE!

Place the handle of the torque wrench against the support. This reduces the free travel to be bridged.

- When you have set the HAZET calibration unit to the test object and inserted the test object correctly, start the software. When you calibrate a HAZET torque wrench, the parameters are pre-set and you can select the HAZET torque wrench from the overview. All test parameters are carried over from the factory settings. Then enter the tester and the serial number. Start calibrating by pres - sing the button for the desired test direction ("left" or "right"). Afterwards, you can adopt the temperature and humidity.

- If you calibrate a torque wrench that is not pre-set in the software, you must fill in all relevant mandatory fields and enter the necessary parameters.

- To do this, create a new test object and fill in all mandatory fields and technical data of the torque wrench. The software and set-up as well as creation is described further in chapter 5. Software.

Notes on calibration:

Set the measurement pick-up to "0" prior to calibration. Press "Start" to commence calibration. The temperature and humidity is queried first. You must adjust the corresponding parameters here! When the torque value is queried, set the torque wrench to the displaced value and reinsert the torque wrench and confirm with "set". The torque wrench is then preloaded. Subsequently, the torque wrench must be set to the measured value of the first measuring point and reinserted. After confirming, the test is started automatically. When the first measuring point is processed, the two additional measuring points must be processed in the same order until the check is concluded.

ATTENTION

When adjusting the torque value on the torque wrench, always ensure the correct and central position of the handle for the support!

After calibration you can add the result and the test object to the test equipment list. Here you can manage the test objects and identify the status. If a test object is due for a test, if it was output, or if the test object is in your warehouse, if it is ready for use or not. You can update the status settings.

NOTE!

When calibrating the HAZET smart-TAC torque wrench, use the HAZET app and have the values displayed directly on the tablet, thus simplifying read-off and entry of the measured values!

⑤ Measurement / Calibration

1. Calibration of indicating torque wrenches:

- if all parameters are updated and entered and the torque wrench is being calibrated,

the displayed value must be entered manually. To do this, read the displayed value of the torque wrench and enter it into the mandatory field.

2. Calibration of automatic-re-lease torque wrenches:

- The program guides you through the calibration.

- The measuring points must – after the torque wrench has been adjusted – be confirmed

Messen

Do not reach into the device during operation!

⑥ Test equipment list

If you have created and calibrated test objects, you can store your test objects in the test equipment list. This is used to monitor the test equipment.

In the test equipment list, you have an overview of the status and location of the test object, the next test date as well as the user and the cost center.

Note: To create an additional test equipment status, you can create and manage new characteristics using master data and test equipment status.

⑦ Uncertainty of measurement

If you want to include new test objects in your test equipment list, you must specify the uncertainty of measurement when you have it. All HAZET torque wrenches already have the uncertainty of measurement stored. If you do not have the data, you must conduct the consideration of the uncertainty of measurement yourself. To do this, you have the option of conducting the consideration of the uncertainty of measurement directly from the measurement or you can go directly to the Uncertainty of measurement tab.

The consideration of the uncertainty of measurement is conducted in accordance with DIN EN ISO 6789:2017.

Caution: When adjusting the torque value on the torque wrench, always ensure the correct and central position of the handle for the support!

Do not reach into the device during operation!

1. Starting calibration

Note: calibration can only be started when you have filled in all relevant mandatory information.

Select a stored test object or create a new object (see description: Create new test objects). Enter the tester and the serial number of the test object.

Note: HAZET torque wrenches are pre-set and can be picked from the pre-selection.

Note: calibration can only start when measurement pick-ups and controller are operational and ① all data has been updated.

Enter the tester and the serial number of your test object.

Note: assignment of the serial number is important for conclusions to be drawn with respect to previous calibrations!
