Peak Hold Function
5.4 Peak Hold Function
Pressing the PEAK HOLD key places the instrument in the peak hold state. Only parameters
whose values exceed the past peak value are refreshed. This function is useful to thoroughly
capture phenomena characterized by instantaneously large values, for example rush current.
During peak hold operation, the PEAK HOLD key is lit up in red, and the [PEAK HOLD] icon on
the screen’s operating status indicator appears.
See “Common screen display” (p. 23).
