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 SIMULATORS
The Joint Simulator (JS) consists of a screw compressing a series of washers enclosed in a case with hex
female head for proper fit to any Kolver torque tester. The head of the joint simulator can be supplied with
different attachment depending on the model used which allows the screwdriver to be connected to the joint
simulator.
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.
Minik1 is supplied with a built-in joint simulator to increase low torque measurements accuracy.
Joint simulators available:

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 MINI KEF and MINI KE/S torque testers consist of a MINI KE torque reader and an external static or
rotary transducer. The static transducer combined with a joint simulator allows you to check the torque
measured by the screwdriver and calibrate it according to your needs. The rotary transducer is the ideal tool
for verifying the real torque applied by the screwdriver directly on the screw (and not on a joint simulator).
Thanks to the modification of the FATC (correction factor) and the SENS (full scale value of the connected
transducer), it is possible to calibrate several external transducers in a single MINI KE reader (see
Programming Menu).
Rotary and non rotary transducers for lower or higher torque ranges available on request.
The minike can read torque up to 500 Nm.

10. 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.
IMPORTANT: the calibration certificate has a maximum validity of 36 months (ref. DIN 51309, ISO 10127-
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.
