AC power supply PCR-LE series

Appendix


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 absolute 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 measuring the current peaks and then taking the maximum absolute 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).

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.
