4. Advanced Operation
PROGRAMMABLE AC/DC POWER SOURCE
126
It is necessary for an electric device with a large inrush current to use a power source with a
sufficient current supplying capability. With a power source that cannot supply a sufficient inrush
current, some electric devices may not start as they are not supplied with necessary power.
This product has the ability to supply peak current up to four times of the RMS rating. You can
measure the maximum inrush current value using the current peak-hold function of the product.
4.5.2 Basics
Output current peak-hold function holds either a positive or negative peak value, whichever is
larger in absolute value.
Current peak-hold value is displayed in all of the Average, RMS, and Peak measurement views
in the Normal View.
Clearing function for the current peak-hold value is provided. The clear operation clears the
current peak-hold value (all phases) to 0 Apk.
--------
Notes
------------------------------------------------------------------------------------------------------------
The peak hold value starts to update again immediately after the clear operation. The clear
operation may not turn the current peak-hold value to 0 Apk even when no current is being
output, because of noise or other reasons.
