Measurements during pulse charge/discharge operation
The measurement method during pulse charge/discharge operation differs between
the PFX2011 and the PFX2021.
PFX2011
During pulse charge/discharge operation, the unit makes measurements at the fol-
lowing times.
If the speci
fi ed pulse time is greater than or equal to 1.5 ms, the current and then the
voltage are measured immediately before the next current value is set as shown in Fig.
A-5. Otherwise, the voltage and then the current are measured as shown in Fig. A-6.
Fig. A-5 Example 1 during Pulse Charge (when the pulse time is
greater than or equal to 1.5 ms)
Fig. A-6 Example 2 during Pulse Charge (when the pulse time is less
than 1.5 ms)
