HIOS HM-100 Torque Value Checking Meters for Automatic Controlled System

Thank you!

Thank you for purchasing the HIOS torque meter.

The HM series torque meters are carefully designed to be exclusively used for automatic controlled systems. This series of torque meters can measure torque without removing the screwdriver mounted on the system.
Please read the following notes carefully before use. We hope you will use our product for a long time.

Features

You can measure the screwdriver torque as it is mounted on the automatic controlled system, and without removing the bit.
The detector is compact and you can easily measure the torque even in a small space.
The digital display helps easy and precise reading.
This instrument can save and indicate peak values for precise measurement.
You can carry around this instrument because it is rechargeable and portable.
You can use commercially available tools for collection as well as analysis of measurement data.
You can also measure the torque of a motor screwdriver for manual use.
● You need to use HIOS’s Fidaptor and a commercially available conversion plug for measurement of the torque of a motor screwdriver for manual use.
A conversion plug allows static (real-time) measurement. For details, please contact us.
Analog outputs can be used for multiple purposes including waveform observation, recording or judgment of measurement results (an analog cord is optional)

Caution
Read the notes below carefully for safe and proper use.

Before using this instrument

Make sure to carefully read this operation manual and the notes attached to the instrument before use for safe and proper use.
The torque meter (display unit) and the detector are calibrated and controlled with the same serial number. Always use the proper combination referring to the serial number.
Please note that HIOS is not responsible for malfunctions caused by unauthorized modification, disassembling and handling of the instrument other than those specified in the operation manual.

Cautions at work

When you measure a rotational device including a screwdriver, pay attention to the surroundings (e.g., working table) so that nothing will be involved in the rotation.
When you detect anything abnormal, stop operation immediately. Wear working clothes properly before starting operation, and fully close the cuffs, buttons and zippers.
Do not wear gloves during operation because they may be slippery.
Since the detector is small, fix it firmly for measurement to avoid it being swung around.
Do not throw around the detector; do not hit it, as such handling may cause the instrument to malfunction.
Since the strain gauge of the detector is sensitive to the surrounding environment, be sure to set it to [TRACK] mode at power-on and confirm zero is displayed. Please adjust it to zero occasionally while in use. (*1)

Notes for use

Never apply the torque exceeding the maximum value displayed on the instrument. If you do so, the instrument will break inside.
For correct handling of Fidaptor, refer to page 5.
Do not use attachments except Fidaptor and other specified attachments.
Do not use the instrument with a device that gives repeated shocks such as an air screwdriver or an impact wrench. (*2)
*When you attach Fidaptor to the socket, always fix it with screws in four directions. (3)**
Do not loosen the screws fixing the socket. (It may cause a precision error.)
For correct handling of the charger, refer to page 12.
Do not connect to the data output connector anything but the devices specified in the operation manual.
When you insert or remove a connector to/from a cord, hold the connector head and check the pin arrangement.
Always turn off the power after finish using the instrument.
Do not hit or apply a load to the display plate (acrylic plate).
Do not change the internal volume for calibration, etc.
Do not handle the detector roughly or drop it.
Do not use the detector in inappropriate places described below:
- A place where water, oil and other fluids may be scattered
- A place where vibrations, dust or heat may exist
- Outdoors and a place where electric noises may exist
- A place with high temperatures and high humidity (preferable temperature: 15°C-35°C, preferable
  humidity: 25%-65%)
- Other places where malfunctions and functional damages may be caused
Do not store the instrument where the temperatures or humidity may change significantly. If you do so, condensation may occur inside the detector resulting in functional damage.

◎ Important

Before performing zero adjustment, set the unit to the TRACK mode and check if “zero” is displayed.
If you want to measure the torque of an air screwdriver or an impact wrench, we have the HIT series for that purpose. Please consult with us.
When you attach Fidaptor to the socket, fix it firmly at four points. (Refer to the external views of the detector on pages 6 and 16.)
If you turn the zero adjustment knob in the PEAK mode, the reset function will be disabled.

Operation procedure

How to check torque using Fidaptor

First, connect the torque meter (HM) to the detector.

Then turn on the power and confirm if the battery has been charged.
・ How to check the battery
① Turn on the power.
② Set the measurement mode to TRACK.
③ 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). Use the chargers for this battery.
(Note) Do not take measurements while charging the battery.
Fix the detector. There are two points for fixing. (See the dimensional drawing of the detector on page 16.)
Connect the cord to the detector.
Connect the cord to the detector. There are two connectors. Use one of them considering the workability.
*Make sure the connector has the correct shape. If you ignore this, it may cause pin bending.
Use the handy screwdriver to loosen the threaded shaft ring of Fidaptor a little.
Set Fidaptor to the socket.
5-1 Fix Fidaptor to the socket

Important
In order to fix Fidaptor, use the L-shaped wrench (1.5mm) to fasten four hollow set screws (M3.0) on the side of the socket with even torque.
This way you can measure in a stable manner.

**5-2. Set the bit end of the target screwdriver to the center of the head screw of Fidaptor.

◎ Important
Notes when fixing Fidaptor:
(1) In order to have the bit set right in the center of the head screw of
Fidaptor, you need to fix Fidaptor by fastening the four screws on theside evenly.
(2) The bit tip should be engaged precisely in the head screw of Fidaptor for measurement (it should be correctly aligned with the thrust direction and the center of the screw.)
(3)** Especially, when you use it in the automatically controlled system, it should be aligned with the center of the Z-axis.

Set the switch for measurement unit change to your desired unit.
Set the mode switch to TRACK and turn the zero adjustment knob for zero adjustment.
Set the mode switch to PEAK.
Turn the screwdriver for measurement.
When the clutch is disconnected, the spring is compressed.
The measurement is displayed in the window and saved.
This is the output torque of the screwdriver.
. Let Fidaptor recover from contraction to return to the constant height.
*Use the handy screwdriver to loosen the threaded shaft.
(Note) Always let the spring recover the constant height by loosening.
Cancel the value in the window by pushing the Reset button.
Repeat the steps 10 to 12 to determine average output torque.
Furthermore, if you want to set any torque, adjust the screwdriver’s nut for torque adjustment and follow the same procedure.
When you finish measurements, always loosen Fidaptor.
At the end of the operation for the day, turn off the power and remove everything from the socket.
(Note) Make sure to loosen the Fidaptor spring at the end of operation and store it.
For aggregation of measurement data, turn the mode switch to PEAK.
For measurement, an input signal (torque = load) of 15 digits or larger is required. If you press the Reset button, the data will be output and the value in the display window will be cancelled. (For the data output tool, refer to the description on page 17.)

About “digit”

“digit” means the unit of a value to be displayed regardless of the decimal point.
(Examples) .0.01 = 1 digit
.025 = 25 digits
.10 = 10 digits
1.25 = 125 digits

How to set the buzzer

(Notes)

Check if the display unit is connected to the detector.
The buzzer is set to 0.981 N・m (HM-10) and 9.81 N・m (HM-100) by default when shipped.

Turn the knob to set the value at which you want to start the buzzer.
Use the zero adjustment knob to set zero on the display.
Check the value after the buzzer.
The buzzer starts sounding when the displayed value reaches the set value.
Stop turning the knob when you hear the buzzer.
Measurement after setting the buzzer
(1) Apply load to the detector.
(2) When the load reaches the preset value, the buzzer starts; and:
In the case of the TRACK mode: The buzzer stops when you release the load; “zero” is displayed.
In the case of the PEAK mode: The display is retained with no load, but the buzzer stops beeping.
When you don’t use the buzzer setting, turn the buzzer set knob to specify the value more than the working value (same as the default).

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

HM-100 has two springs: black (strong) and yellow (weak).
A black spring is attached to the Fidaptor.
If you measure a smaller range of torque, replace the black spring with the yellow one.
(Note) Set the bit of the screwdriver to the Fidaptor’s head screw and turn it counterclockwise.
Then the threaded shaft becomes loose to enable replacing the spring.

Inspection of Fidaptor

Handling of Fidaptor

Never apply a load more than the measurement capability specified for Fidaptor.
Use Fidaptor appropriate for the screwdriver and the torque.
Always keep Fidaptor loose and remove everything from the socket after measurement.
Try to keep the screwdriver and Fidaptor upright while measuring and apply the thrust load of 5kg or smaller.
(In the case of a lower range of torque, the thrust load should be 2kg or smaller.)
For continuous measuring, apply grease to the component parts of Fidaptor.
Set the measurement cycle to 5 seconds or longer. If you set the cycle to a time different to that, the component parts will wear quickly.
Never leave or store Fidaptor in a fastened state.
When you don’t use Fidaptor, loosen the spring.
Correctly engage the object for measurement and Fidaptor.
Don’t use a deformed or modified Fidaptor.
