Typical materials able to be tested include many manufactured items, such as springs, electronic components, fasteners, caps, films, mechanical assemblies, and many others. Items that should not be used with the sensor include potentially flammable substances or products, items that can shatter in an unsafe manner, and any other components that can present an exceedingly hazardous situation when acted upon by a force.
Model 3i Digital Force/Torque Indicator User’s Guide 5. When battery life drops to approximately 2%, the indicator from step 4 will be flashing. Several minutes after (timing depends on usage and whether the backlight is turned on or off), a message appears, “BATTERY VOLTAGE TOO LOW. POWERING OFF”. A 4-tone audio indicator will sound and the indicator will power off. The indicator can be configured to automatically power off following a period of inactivity.
