»RI2 Cogs h=li*Hion TsSl= • A compact instalment to verify the electrical quality of a strain gage installation before it is • To read insulation resistance (leakage) to • To measure the deviation of installed gage resistance from precise standard to a resolution • Ohmmeter scale to diagnose and solve questionable installations • To verify the complete gage circuit including After installing strain gage, the main quality verification and examination test are the isolation impedance and resistance shift. The strain gage is made by foil alloy. Its isolation impedance after installing is more than 20 GO. Use room-temperature curing adhesive, the gage resistance shift value must be less than 0.5%. Use bake curing adhesive, the gage resistance shift value must be less than 2%. When G. F. is 2, the resolution of GT2, being a strain indicator, is 2 u£ .
