Delay time guideline
If the measurement target, for example, is an inductor that takes longer to
stabilize after applying a measurement current, and it cannot be measured with
the initial delay (preset), adjust the delay. Set the delay time to approximately
ten times the following calculation so that the reactance component (inductance
or capacitance) does not affect the measurement.
L: Measurement target inductance
R: Measurement target resi lead wire resi contact resistance
I: Measurement current (see: “Accuracy”)
V
〇
: Open-circuit voltage (see: “Accuracy”)
Start with a longer delay time, and decrease the time gradually, watching the
measured value.
As the delay is longer, the measured value display is slower to refresh.
