RC04-PCR-LA
Operation Method 4-11
Peak Holding Value Measurement
Peak holding value measurement holds the maximum peak value
until a peak clear signal is received. One of the following signal
applies to generate a peak clear operation. Peak holding current mea-
surement is useful in measuring inrush current of a load occurring at
power ON.
The Remote Controller’s peak holding value measurement measures
peak current using the analog peak holding circuit. It obtains the max-
imum absolute value of that data. Therefore, peak current display
shows an absolute value, which has no positive or negative symbol.
The peak holding value can be measured in the AC, DC, or AC + DC
mode.
Peak Clear Procedure
The following three methods can be used to clear a peak in the peak
holding current measurement.
• Press the F4 (clr) key on the Remote Controller.
• Short circuit the input of the PEAK INIT IN terminal (BNC con-
nector) on the upper rear of the PCR-LA power supply (see the
Description on page 4-12).
• Send a peak clear message via the GPIB or RS-232C interface (see
the PCR-LA AC Power Supply Operation Manual).
Peak Holding Current Measurement Mode Operating Proce-
dure
Press the (SHIFT, F3) keys in the same way as current measurement
mode change. This causes the indication to change in the following
order in the AC mode.
In the DC or AC + DC mode, the indication changes as follows:
Where “Ip” is peak current value display and “Iph” is peak holding
current value display.
