Safety Instructions:

WARNING:

• If something abnormal occurs, do not open the cover. Request repair from the retailer where you purchased the product.
• Do not put foreign objects or water into the unit. Spillingliquid or placing a container with water on top of the unit could cause malfunction.
• Do not use the unit with any power supply voltage other than that specified.

CAUTION:

• Avoid installing the unit in locations exposed to smoke, steam,unstable stands, tilted places, high humidity, dust, or direct sunlight.
• Cut the power supply when not using the unit for a longtime.
• Do not operate a damaged unit.

Precautions for Use

• The load cell is not water or splash resistant and should not be used in high humidity or corrosive gas atmospheres.
• Avoid contact with water, oil, and other substances.
• Avoid use in conditions where condensation could occur.
• Discharge static electricity from your body before connecting cores to the load cell.
• Sudden temperature changes may affect measurement accuracy. Avoid locations with sudden temperature fluctuations.
• Perform load calibrations periodically.

Installation Procedures:

When using with compression:

• Attach the load button and tighten it with the specified torque to prevent loosening. Do not exceed the tightening torque when removing the load button.
• Use a thread-locking fluid on the screw if desired, but note that it may prevent removal of the load button.

When using with a tensile load:

• Attach a rod end or tensile load adapter.

Fixing the load cell to the attachment surface:

• Insert screws (steel hexagon socket head cap screws) into the screw holes near the edge of the load cell.
• Ensure the attachment surface is flat to maintain outputprecision.
• The size and number of screws depend on the rated capacity (model name) of the load cell.

IMPORTANT SAFETY INSTRUCTIONS

WARNING
If something abnormal occurs
Request repair from the retailer where you purchasedthe product.
Do not open the cover.
Never remove the cover from this unit. Doing so could cause malfunction. Request inspection and repair from the Use screws with a strength grade of 12.9.

In addition, the length of thread engagement for thescrew and the mounting part (internal threads) shouldbe about twice the nominal diameter of the screw.Please consult with us if you are uncertain about screwselection, for example.

• Since tightening screws will cause their heads to contact the coated surface of the load cell, which could scrape the coating, use flat washers with the screws so that the washers contact the load cell instead.  Even using flat washers, the coating could be scraped if the flat washers are turned. By using a metal washer like the one shown in the illustration below, you can avoid scraping the coating even more.
• When attaching a rod end to a load cell, use a nut to prevent loosening. When tightening this nut for the prevention of loosening, do not allow the counterforce to be applied to the load cell. (Do not hold the entire load cell in place whiletightening the nut.) If twisting force is applied between the central screw part and the surrounding screw holes,that force could be transferred to the load detection part and damage it. For this reason, when attaching the nut, hold the rod end side in place. retailer where you purchased the product. Do not alter this unit. Doing so could cause malfunction.

Do not put foreign objects or water, for example, into the unit.
Do not place a container that holds water, for example, on top of this unit. If liquid is spilled, for example, and entersthe unit, this could cause malfunction.
Do not use the unit with any power supply voltage other than that specified.
Do not use the unit with any power supply voltage other than that specified. Doing so could cause malfunction.

CAUTION
Unsuitable installation locations
Do not place the unit in the following types of locations.
Doing so could cause malfunction.

• Locations where it might be exposed to smoke or steam, such as near a kitchen table or humidifier
• Unstable locations, including unsteady stands and tilted places
• Locations that are very humid or dusty
• Locations that are exposed to direct sunlight
  When not using the unit for a long time
  For safety, cut the power supply when not using this unit for a long time.

Do not operate a damaged unit.

Precautions for use

• This unit is not built to be water or splash resistant, and it cannot be used in conditions when the relative humidity is high. Moreover, use in atmospheres with corrosive gases should be avoided.
• Be careful to prevent water, oil and other substancesfrom getting on the unit.
• Avoid use in conditions where condensation could occur
• In addition, always use screws that are suitable for the rated capacity when attaching a base plate or tensile load adapter, for example, to a load cell. Use flat washers together with these screws. When tightening the rod end nut, do not let the counterforce be applied to the load cell. (Hold the rod end side.) Moreover, tighten each of the attachment screws evenly.
• As shown in the illustration below, there is a level change between the outer circumference and the central screw portion of the load cell attachment surface. This gap functions as a stopper when the load cell is overloaded in the compression direction. For this reason, be aware that if the attachment surface is uneven, rough, dusty or dirty, for example, the stoppercould function at a load lower than the rated capacity and produce inaccurate measurement results.
• Connect cores to the load cell after discharging (eliminating) static electricity from your body.
• If the surrounding temperature changes suddenly, the values output by this device could become unstable, making accurate measurement impossible.(This could occur, for example, in a location blown bywarm or cold air.)
• Conduct load calibrations periodically.

Installation procedures

• Attach the load button when using with compression. Tighten with the torque shown in the table below to prevent the load button from becoming loose. When removing an attached load button, be sure notto apply torque that exceeds the tightening torque shown in the table.

Rated capacity| Tightening

torque

| Load button

screw dimension

---|---|---
200 N – 1 kN| 3 N·m| M8
2 kN – 5 kN| 3 N·m| M12

A thread-locking fluid can be used on the screw, but be aware that this could prevent removal of the load button.

• When using with a tensile load, attach a rod end or tensile load adapter.
• Insert screws (steel hexagon socket head cap screws) into the screw holes near the edge of the load cell, and fix it to the flat attachment surface. (Output precision could be affected if the attachment surface is not flat.) The size of the screws used and their number depends on the rated capacity (model name) of the load cell as shown below

Precautions when placing loads on the unit

• Make sure the load is perpendicular to the surface to which this unit is attached.
• Apply the load so that it is centered on the center of the unit. If the load is not centered (eccentric load), twisting, for example, and measurement errors couldoccur. This could even result in damage.
• Apply the load so that it is centered on the center of the unit. If the load is not centered (eccentric load),twisting, for example, and measurement errors couldoccur. This could even result in damage.
• oo If the load receiving area is contacted by something that is at a different temperature and the load is increased, the values output by this device could become unstable, making accurate measurement impossible.In such a case, wait until the temperature differenceceases to exist before measuring.

Electrical connection of load cell

• Connect as shown in the illustration below. Incorrect connections could result in inability to balance and in errors occurring in the output voltage when loads are applied.

Using a cable with bare lead wires

• This unit does not support remote sense. See the operation manuals of indicators and strainamps that support remote sensing for how to connect sensors with those units.
• The shield is not connected to the main body of this product. For this reason, if grounding is necessary because of external noise or another issue, arrange toground the shield to a part other than the body of thisunit, for example.
• Since the cable is directly connected to this unit, use a specialized cable to increase the length. (Pleaseconsult with us.)
