Peak Hold Current Measurement - Kikusui PCR500LE User Manual

Peak hold current measurement

The differences between the peak measurement and the peak
hold measurement are shown below.
„ Peak measurement
„
The peak measurement is cleared once per measurement
cycle.
The PCR-LE Series makes peak measurements by measuring
the current peaks and then taking the maximum absolute value
of the measured data. The peak current display shows an ab-
solute value with no positive or negative sign. The peak value
can be measured in AC, DC, and AC+DC modes.
„ Peak hold measurement
„
The peak hold measurement is held until the maximum peak
value is cleared. The peak hold current measurement is useful
when you are measuring the inrush current when the power is
turned on and in similar situations.
The PCR-LE Series makes peak hold measurements by mea-
suring the current peaks and then taking the maximum ab-
solute value of the measured data. The peak current display
shows an absolute value with no positive or negative sign. The
peak hold value can be measured in AC, DC, and AC+DC
modes.
You can capture peaks that continue for at least a specified
length of time (t).
1
In AC mode, t=
256 x f
0
In DC mode, t= 20 s
The peak current depends greatly on the PCR-LE's current
supply capabilities. Ensure that the output capacity of the PCR-
LE Series is sufficient for the load.

f is the output frequency.
