The signal acquisition time at frequency below 1Hz is about one cycle of the signal.
Figure 3–6 Signal acquisition time
Measurement time of DC resistance
When DC resistance Rdc is selected as a secondary parameter, DC resistance is measured
following the measurement of AC impedance. “Figure 3-5 Measurement sequence” (c)
Accordingly, the measurement time is the sum of the following three values:
・Measurement time of AC impedance
・Automatic range selection time of DC resistance (about 75 ms 1 to 75ms 5)
The measurement range of DC resistance is automatically selected unless the range
is held by remote control.
The adjustment time of measurement range varies depending on the DC resistance.
・Additional time to measure DC resistance “Table 3-4 Example of measurement
time” (DC)
Measurement time when trigger delay time ≠ 0
・Measurement time of AC impedance is extended by the amount of trigger delay time.
・Automatic range selection time of DC resistance is extended by about maximum amount
of trigger delay time.
・Measurement time of DC resistance is extended by about (trigger delay time 40ms) 2
when trigger delay time > 40ms.
