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 whose isolation impedance value after installing is bigger than 20 GΩ.
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 and as a strain indicator, the resolution of GT2 is 2.

● A compact instrument to be used to verify the electrical quality for the strain gage installation BEFORE it is placed in service.
● Insulation resistance ( leakage ) can be read to 20,000 MΩ with 15 VDC.
● Deviation of installed gage resistance can be measured from precise standards to a resolution of 0.0001 %.
● Ohmmeter scale to troubleshoot questionable installation.
● To verify the complete gage circuit including lead-wires.
