How to test the internal and external resistance of the anti-static wrist ring
The simple internal/external resistance test steps of the anti-static wrist ring are as follows:
Place the inside/outside of the wrist ring tightly on the two cylinders of the fixture
Connect the cylinder above the fixture to the ohmmeter
Connect the ground wire to the wrist strap and connect it to the ohmmeter
Use a jig to apply pressure to the wristband, observe the changes in the test data of the ohmmeter and record the resistance data
The test standards for the internal and external resistance of the anti-static wrist ring are as follows:
Internal resistance: <1×105 ohms
External resistance: >1×107 ohms
