Operation procedure

How to check torque using Fidaptor

1. First, connect the torque meter (HM) to the detector. Then turn on the power and confirm if the battery has been charged.
2. How to check the battery: Turn on the power. Set the measurement mode to TRACK. If the battery is low, "LOBAT" is displayed in the upper left corner of the display. Then, charge the battery (do not charge longer than eight hours) using the provided chargers. (Note) Do not take measurements while charging.
3. Fix the detector. There are two points for fixing (see dimensional drawing on page 16).
4. Connect the cord to the detector. Use one of the two connectors, considering workability. Ensure the connector shape is correct to prevent pin bending. (Note) Use one connector and cover the other with a cap.
5. Use a handy screwdriver to loosen the threaded shaft ring of Fidaptor slightly. Loosen the shaft so the spring can be turned with fingers; the shaft should always return to the same position.
6. Set Fidaptor to the socket.
7. 5-1 Fix Fidaptor to the socket: Use the L-shaped wrench (1.5mm) to fasten the four hollow set screws (M3.0) on the side of the socket with even torque for stable measurement.
8. 5-2. Set the bit end of the target screwdriver to the center of the head screw of Fidaptor.

   Notes when fixing Fidaptor:

   • Fix Fidaptor by fastening the four screws on the side evenly to ensure the bit is centered in the head screw.
   • The bit tip should be engaged precisely in the head screw of Fidaptor for measurement, aligned with the thrust direction and screw center.
   • When used in an automatically controlled system, it should be aligned with the center of the Z-axis.
9. Set the switch for measurement unit change to your desired unit (N·m, lbf·in, kgf·cm).
10. Set the mode switch to TRACK and turn the zero adjustment knob for zero adjustment. Check if "000" is displayed. (Note) Zero adjustment is not available in PEAK mode.
11. Set the mode switch to PEAK. After measurement, clear the value with the RESET button.
12. Turn the screwdriver for measurement. When the clutch disconnects, the spring compresses, and the measurement is displayed and saved. This is the output torque.
13. Let Fidaptor recover from contraction to return to constant height. Use a handy screwdriver to loosen the threaded shaft. (Note) Always let the spring recover height by loosening.

    The target looseness is that the spring can be turned with fingers to always have a constant height.

14. Cancel the value in the window by pushing the Reset button.

    Note for resetting:

    • Let Fidaptor return to constant height before pressing RESET.
    • Ensure the socket section has no load; it cannot be reset if there is a load.
    • If the measurement result is high torque, the value may remain. Press RESET again if necessary.
15. Repeat steps 10 to 12 to determine average output torque. Adjust the screwdriver's nut for torque adjustment if needed.
16. When finishing measurements, always loosen Fidaptor. Turn off the power and remove everything from the socket at the end of the day. (Note) Loosen the Fidaptor spring and store it properly.
17. For aggregation of measurement data, turn the mode switch to PEAK. An input signal (torque = load) of 15 digits or larger is required. Pressing the Reset button outputs data and cancels the display value. (Refer to page 17 for data output tools.)
18. About "digit": "digit" means the unit of a value displayed regardless of the decimal point. (Examples: 0.01 = 1 digit, 0.025 = 25 digits, 0.10 = 10 digits, 1.25 = 125 digits)

How to set the buzzer

Diagram showing the buzzer set knob and zero adjustment knob on the HIOS HM-100. Notes state the buzzer is set to 0.981 N·m (HM-10) and 9.81 N·m (HM-100) by default.

Setting procedure

1. Turn on power.
2. Set to TRACK mode.
3. Use the zero adjustment knob to set the value.
4. Turn the buzzer adjustment knob to set the desired buzzer start value. The buzzer sounds when the displayed value reaches this point. Stop turning when the buzzer is heard.
5. Confirm the value.
6. Set zero on display using the zero adjustment knob.
7. Measure in PEAK mode and check the value after the buzzer.

Measurement after setting the buzzer

• Apply load to the detector.
• When the load reaches the preset value, the buzzer starts.
• In TRACK mode: Buzzer stops when load is released; "zero" is displayed.
• In PEAK mode: Display is retained with no load, but buzzer stops beeping.

If the buzzer setting is not used, turn the buzzer set knob to a value higher than the working value (default setting).

How to replace the spring (attached to HM-100)

HM-100 has two springs: black (strong) and yellow (weak). A black spring is attached by default. For measuring a smaller torque range, replace the black spring with the yellow one.

(Note) Set the screwdriver bit to the Fidaptor's head screw and turn it counterclockwise. The threaded shaft will then loosen, allowing spring replacement.
