1. Mounting holes
2. Display 4 digit / 8 lines
3. “ON/OFF” key : press for 3 seconds to switch tester on or off
4. “CLEAR” key : press to reset the displayed value
5. “UNIT” key : press to select the unit of torque measurements
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
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.
When you select Auto reset “Con”: any new measure will replace the previous one without resetting the
value to zero.

9. 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:
Model
Torque range Nm
KTE5
0.5 –5.0
KTE25
2.0 –25.0
Rotary and non rotary transducers for lower or higher torque ranges available on request.
10. SERIAL PRINT
It is possible to print the results through the serial port placed near the power supply connector.
The serial print has the following settings:
VALUE - UNIT OF MEASUREMENT
Example of serial print:
0,247 Nm
0,249 Nm
0,255 Nm
0,254 Nm
0,249 Nm
0,255 Nm
0,247 Nm
11. 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 nominal value. Damages
due to overloading will result in inaccurate readings and will not be covered by our warranty.
