Notes
46. 3.5 digits, autozero off, 0.0005 PLC, excludes measurement time.
47. DCV = 10 V; 2-wire or 4-wire = 1 kΩ; DCI = 1 mA; ACI = 1 mA; ACV = 1 V; Capacitance = 10 µF.
48. 2-wire function for 100 Ω range and up. For the 10 Ω range, add 2.7 ms.
49. 4-wire function for 100 Ω range and up. For the 1 Ω and 10 Ω ranges, add 2.7 ms.
50. When ranging to 10 V and above, add 1.8 s.
51. SCPI programmed using 4-byte binary format.
