Characterize the calibrator for 1 Ω and 10 Ω
To characterize the calibrator:
1. Connect the calibrator and the reference DMM as shown in the figure below.
2. On the calibrator, enable the OPR key and the EX SNS key.
3. Ensure that the OPERATE display and EX SNS key are illuminated.
4. Source 0 Ω.
5. On the reference DMM, enable 4-wire resistance and 2 Ω range.
6. Select Ω PLUS, then TruΩ, Resl to RESL '7', and Fast OFF.
7. Verify 0 Ω.
8. Perform range ZERO as required.
9. On the calibrator, source 1 Ω.
10. On the reference DMM, record 1 Ω reading.
11. Use the reading as the target for the Model DMM7510 1 Ω verification.
12. Repeat these steps for 10 Ω characterization.
