Temperature Coefficient (0°–18°C and 28°–50°C)
±(0.15 × accuracy specification)/°C.
Source I Mode, Manual Ohms Total uncertainty = I source accuracy + V measure accuracy (4-wire remote sense).
Source V Mode, Manual Ohms Total uncertainty = V source accuracy + I measure accuracy (4-wire remote sense).
6-wire Ohms Mode Available using active ohms guard and guard sense. Max. Guard Output Current: 50 mA (except
1 A range). Accuracy is load dependent. Refer to White Paper below for calculation formula:
“Obtaining More Accurate Resistance Measurements Using the 6-wire Ohms Measurement Technique.”
Guard Output Impedance <0.1Ω in ohms mode.
NOTES
1. Speed = Normal (1 PLC). For 0.1 PLC, add 0.005% of range to offset specifications, except 200 mV, 1 A, 10 A ranges, add 0.05%. For 0.01 PLC, add 0.05% of range to offset
specifications, except 200 mV, 1 A, 10 A ranges, add 0.5%.
2. Accuracies apply to 2- or 4-wire mode when properly zeroed.
3. Manual ohms only – except 2420, 2440 for 2 Ω range and 2400, 2401, or 2410 for 200 MΩ range.
4. Source readback enabled, offset compensation ON. Also available on 2410, 2420, and 2440 with similar accuracy enhancement.
5. In pulse mode, limited to 0.1 PLC measurement.
6. Except 2440; default test current is 5 µA.
7. Except 2440; default test current is 0.5 µA.
