MOUNTING

It is strongly recommended securing the tester through slots “1” to a workbench before operating. Immobilizing the tester when checking torque values over 1 Nm is critical for the safety the operator as well as for the accuracy of torque measurements during operation.

JOINT SIMULATOR

The Joint Simulator (JS) consists of a screw compressing a series of washers. The way the washers are mounted can simulate soft or hard joint. The screw comes with a ¼” hex male head for proper fit to any ¼” hex female screwdriver drive. Hardened thread components increase accuracy and life. Since a joint simulator cannot duplicate actual joints, the torque values displayed on the minik may vary from the actual torque that a screwdriver will apply to the actual assembly. When critical applications are involved, we recommend to verify the torque output of the power tool being used on the actual assembly through an external transducer.
Minik1 is supplied with a built-in joint simulator.

NB. We recommend to grease the JS each 1000 cycles.

STARTING AND OPERATING THE TESTER

1. Immobilize the tester when checking torque values over 1 Nm. This is critical for the safety the operator as well as for the accuracy of torque measurements during operation.

2. Switch the tester on pushing the ON/OFF key. If used only with battery check its status. If the tester does not switch on or the display is not clear enough, please replace the battery. When used it the AC adapter, this will disable the battery. The battery is not rechargeable. The display will show the main screen:

3. Insert the joint simulator into its 13mm hex seat and make sure the screw is in its upper position (if not run the driver anticlockwise to unscrew it). The tester is ready for a measuring cycle.
   In minik1, only unscrew before measuring.

4. Run the joint simulator screw all the way down until it stops and read the torque value on the display. Run the screw up to be ready for the next cycle.

5. Press the “ON/ESC” key for 3 seconds to switch the tester off. The tester features a built-in auto shut off mode function to save power when not in use. If there is no activity for 3 minutes, such as key press or no torque input, the tester will shut down. To restore power press the “ON/ESC” key for 3 seconds

NB. Before starting, always check that the screen displays 0.000. Instead push CLEAR.

SELECTING THE UNIT

To change unit: press Unit key until the desired unit has been selected. Each unit is indicated by a LED of different color: red for Nm, green for kgf. cm and yellow for lbf.in .

SELECTING MANUAL OR AUTO RESET

The flow chart below shows how to select Manual or Auto Reset. Sens, Cal and Fatc functions (sensitivity, calibration and correction factor) can be modified only by authorized personnel. When you select Manual Reset “Coff”: you need to push “CLEAR” to remove readings from the display and reset all values to zero. Vers. 020221 When you select Auto reset “Con”: any new measure will replace the previous one without resetting the value to zero.

EXTERNAL TRANSDUCER for miniKe

The minike readouts support an external rotary or non rotary transducer. The minike can read torque up to 500 Nm. The external transducer must be calibrated together with the minike here at Kolver before shipment. The following transducers are always available ex stock:

Rotary and non rotary transducers for lower or higher torque ranges available on request.

KTE5-KTE25

KTE50

MAINTENANCE

The minike testers are maintenance-free. The electronics and the internal transducers have no wearing parts except the battery once its charge is over. The internal transducer should be calibrated every 12 to 30 months, depending on the frequency of use.

WARNING: The overload protection of the internal transducer is limited to 125% of the nominal value. Damages due to overloading will result in inaccurate readings and will not be covered by our warranty.

IMPORTANT: the calibration certificate has a maximum validity of 26 months (ref. DIN 51309, ISO 6789-2). The instrument must be calibrated again (regardless of the date of last calibration):

• if it has been overloaded
• after any corrective maintenance (eg: upgrade with new software)
• after improper use (eg: tested with impact wrench or jacks)
• in case of doubt about the measurement results.

KOLVER TORQUE ANALYZER
Torque Analyzer software allows for communication between our mini k/s and mini ke/s series torque testers and your PC. Torque Analyzer software allows the capture of torque measurements directly from the torque tester including track mode, graphic display readings, and the real-time calculation of the machine capacity represented by Cm and Cmk dat0061.

INSTALLATION

Torque Analyzer is plug-and-play software. Just launch the “Kolver_Torque_Analyzer_ver_X_X_X.exe” (X_X_X is the version of the software).

Kolver_Torque_Analyzer_ver1_0_1 software main screen The home page is made of three sections:

1. Control Panel”: to display results, graphics, tables, settings,s, and info of the tester.
2. “Report”: to display values (max, min, cm, cmk, in total, in real-time…etc.)
3. “Interface”: connection, modification and export of data.

CONNECTION TO MINIK/S

Connect the minik/s to your pc through the usb port. Then push the Connect button. The software will display the correct connection (see Picture 2). Unless it will show the error and how to proceed.

TORQUE VALUE CAPTURE

How to capture the torque values:

1. Track Mode: it allows to capture and display the trend of the torque signal given by the minik/s.
2. Max Value Mode: it allows to capture and display the max torque value given by the minik/s.

The mode must be set on the minik/s: on the main screen flag or not the Track option. However, Torque Analyzer has been designed to automatically align the receipt of the first measure by detecting the capture mode set in mini k.
