• When the current limiter range is 320 A to 10 A: Ts = 0.3 + (0.8 + 7500/DIL)  Vs/100 [ms]
Example: Ts unit (ms)
(2) Current source
The 6243/44’s settling time (Ts) becomes, in accordance with the current source change value (Is),
the current sense resistance (Rs) and the load voltage, (V
RL = R L · Is).
Set the Measure Delay (Td) higher than Ts.

Example 1: When 0.2 mA is applied to a 100 k resistor in the 3.2 mA range
Is = 0.2 mA
V
RL = 0.2 mA  100 k = 20 V
28 V
RL = 28  20 = 560 s
9 V
RL / (Rs· Is) + 200 = 9  20 / (220  0.2 mA) + 200
= 4291 s
From this follows that Ts = 4291 s
Make setting so that Td  4.29 ms
