- The equipment listed in table 2 is necessary to do the calibration and test for the 712b the equipment listed in table 3 is necessary to do the calibration and test for the 714b
- Required equipment
- Note fluke 5522a and fluke 8508a need an 8 hour warmup period before the calibration starts the 5522a needs to zero all the functions weekly and zero ohms output function every day the 8508a needs to zero the dc v measurement function the 4 wire ohms measurement function and the dci measurement function
- B 714b
- B performance verification
- Verify ohms source
- Verify 4 wire ohms measure
