Operation Manual(August 2024)

ET-C005 24A

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
1.	You can measure the screwdriver torque as it is mounted on the automatic controlled system, andwithout removing the bit.
2. The detector is compact and you can easily measure the torque even in a small space.
3. The digital display helps easy and precise reading.
4. This instrument can save and indicate peak values for precise measurement.
5. You can carry around this instrument because it is rechargeable and portable.
6. You can use commercially available tools for collection as well as analysis of measurement data.
7. 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 measurementof the torque of a motor screwdriver for manual use.
A conversion plug allows static (real-time) measurement. For details, please contact us.
8.	Analog outputs can be used for multiple purposes including waveform observation, recording or
judgment of measurement results (an analog cord is optional).

CautionRead 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 tomalfunction.
● 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)-2-Notes for use● Never apply the torque exceeding the maximum value displayed on the instrument. If you do so, theinstrument 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 pinarrangement.
● Always turn off the power after finish using the instrument.
● Do not hit or apply a load to the display plate (acrylic plate).
