The auto range delay function is enabled only in current measurement (IM) auto range.
The auto range delay function does not work in the fixed range or voltage measurement (VM).
The auto range delay (Tar) is set as a value with respect to the 30 μA range. For other ranges, the value is
set in 1/10 multiples, as shown in the table below.
• Tar target
Calculate the Tar setting using the expression below.
Tar = = 1500 × C
L [s]
(Example) If C
L = 1 μF
Tar = 1500 × 1 μ = 1.5 ms
Set Tar = 2 ms
