NOTES
1. 2400, 2401, 2410 Only: Specifications valid for continuous output currents below 105mA. For operation above
105mA continuous for >1 minute, derate accuracy 10%/35mA above 105mA.
2. Full operation (1A) regardless of load to 30°C (50°C for Model 2420 and 2440). Above 30°C (50°C for Model
2420 and 2440) ambient, derate 35mA/°C and prorate 35mA/W load. 4-wire mode. For current sink operation
on 1A, 3A, or 5A 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, 1µA to 100mA range, accuracy is:
Model 2400, 2401: ±(0.15% + offset*4). Models 2410, 2420, 2425, 2430, 2440: ±(0.5% + offset*3).
For 1A range, accuracy is:
Model 2400, 2401: ±(1.5% + offset*8). Models 2410, 2420, 2425, 2430, 2440: ±(1.5% + offset*3).
4. 10A range only in pulse mode. Limited to 2.5ms 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 200mV, 1A, 10A
ranges, add 0.05%. For 0.01 PLC, add 0.05% of range to offset specifications, except 200mV, 1A, 10A 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.
8. Model 2400 and 2400-C only.
