• Preforming measurement with a strain gauge requires a bridge box. Use a strain gauge and bridge box
both of which are commercially available.
• The bridge box may be susceptible to the effect of noise. For more information about how to ground the
bridge box, refer to its instruction manual or contact the manufacturer of the bridge box.
• Do not excessively bend the cable and the base between cable and connector, pull on them, nor twist
them. Doing so may cause the conversion cable to break.
