6. Internal transducer or port for external transducer

4. 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.

5. 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.

6. 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.

7. SELECTING THE UNIT

MEASURING UNIT: Nm, kgf.cm and lbf.in

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 .

8. SELECTING MANUAL OR AUTO RESET
