2. For the voltage-source
Settling time (Ts) of the 6241A/6242 is defined by the changes in voltage-source value (Vs), the cur-
rent-limiter set value DIL (digit), and the settling time setting (Fast/Slow), as shown below.
Set the measurement delay (Td) to Ts or over.
• Fast mode
Current-limiter range is 300 μA to 500 mA
Ts=50+(Vs × 30000/DIL) [μs]
Current-limiter range is 30 μA
Ts=(50+(Vs × 30000/DIL)) × 3[μs]
Current-limiter range is 3 A, 5 A
Ts=(50+(Vs × 30000/DIL)) × 4 [μs]
•Slow mode
Current-limiter range is 300 μA to 500 mA
Ts=300+(Vs × 100000/DIL) [μs]
Current-limiter range is 30 μA
Ts=(300+(Vs × 100000/DIL)) × 1.25 [μs]
Current-limiter range is 3 A, 5 A
Ts=(300+(Vs × 100000/DIL)) × 1.5 [μs]
Example) Ts values when current-limiter range is 300 μA to 500 mA Units [μs]
NOTE: 500 mA range is available for 6241A only. 3 A, 5 A ranges are available for 6242 only.
