4.9.2 Measure Delay and Settling Time

Example 2: When 0.2 mA is applied to a 100 k resistor in the 320 A range
Is = 0.2 mA
V
RL = 20 V
28 V
RL = 560 s
9 V
RL / (Rs· Is) + 200 = 9  20 / (2.2 k  0.2 mA) + 200
= 609 s
From this follows that Ts = 609 s
Make setting so that Td  610 s
When a capacitive load (C
L ) is connected as the load, time is also required for C L charging in addition
to the settling time described above.
Tc = Tc: Charge time
Set Measure Delay (Td) higher than the higher of the Ts and Tc described above.
Example 3: When a current is applied at 1 A and until it reaches 20 V for 0.1 F in the 32 A
range
Is = 1 A
V
RL = 20 V
TS = 35 V
RL / (Rs· Is) = 35.20 / (22 k · 1 A)
= 31.8 ms
Tc = C
L · V RL / Is = 0.1 F · 20 V / 1 A = 2 s
Make setting so that Td  2 s
