As shown in Fig. A-7, voltage measurement and current measurement are per-
formed independently at the same time regardless of the speci
fi ed pulse time width.

Pulse voltage measurement
PFX2011 and PFX2021
The following two types of measurement modes are available for pulse voltage
measurement.
1. Peak measurement
Measures the maximum and minimum voltages in one pulse cycle. If a pulse cur-
rent with a short time width is repeated, this measurement method is often used.
2. Point measurement
Measurement is performed according to the speci fi ed measurement points (2
points). This is useful when you wish to arbitrary fi x the measurement point.
• If the battery voltage fl uctuation is large with respect to the change in the pulse
current as shown in Fig. A-8, the measured voltage returns an average value
within the conversion period.
