NOTES
1. 2400, 2401, 2410 Only: Specifications valid for continuous output currents below 105 mA. For operation above 105 mA continuous for >1 minute, derate accuracy 10%/35 mA above
105 mA.
2. Full operation (1 A) regardless of load to 30°C (50°C for 2420 and 2440). Above 30°C (50°C for 2420 and 2440) ambient, derate 35 mA/°C and prorate 35 mA/Ω load. 4-wire mode. For current sink operation on 1 A, 3 A, or 5 A ranges, maximum continuous power is limited to approximately 1/2 rated power or less, depending on current, up to 30°C ambient. See power equations in the User’s Manual to calculate allowable duty cycle for specific conditions.
3. For sink mode, 1 µA to 100 mA range, accuracy is: 2400, 2401: ±(0.15% + offset*4). 2410, 2420, 2440: ±(0.5% + offset*3). For 1A range, accuracy is: 2400, 2401: ±(1.5% + offset*8). 2410, 2420, 2440: ±(1.5% + offset*3).
4. 10 A range only in pulse mode. Limited to 2.5 ms pulse width maximum. 10% duty cycle maximum.
5. 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%.
6. Accuracies apply to 2- or 4-wire mode when properly zeroed.
7. In pulse mode, limited to 0.1 PLC measurement.

| 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. |
