TEMPERATURE COEFFICIENT (0°–18°C & 28°–50°C): ±(0.15 × accuracy specification)/°C.
CURRENT REGULATION: Line: 0.01% of range. Load: 0.01% of range (except Model 2440
5A range 0.05%) + 100pA.
VOLTAGE LIMIT: Bipolar voltage limit (compliance) set with single value. Min. 0.1% of range.
OVERSHOOT: <0.1% typical (1mA step, RL = 10k
Ω, 20V range for Model 2400, 2410, 2420, 2425,
2430), (10V range for Model 2440).

NOTES
1. 2400, 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/ Ω 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: ±(0.15% + offset*4). Models 2410, 2420, 2425, 2430, 2440: ±(0.5% + offset*3).
For 1A range, accuracy is:
Model 2400: ±(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.
