4.9.4 Auto Range Delay
This function is used for measuring a capacitive load (C
L
) by voltage source current measurement
(VSIM).
When voltage is applied to the C
L
and current measurement is conducted using the Auto Range, the
current value drops when the C
L
is charged and the measurement range is lowered.
Using this delay, The current value change generated when the measurement range is switched is
measured.
The Auto Range Delay function is only valid with the current measurement (IM) Auto Range.
The Auto Range Delay function does not function for fixed range and the voltage measurement (VM)
Auto Range
The Auto Range Delay (Ta) is set as a value for the 32 A range for both 6243 and 6244, and for the
other ranges a 1/10-value is set for each range as shown in the following table.
