Why Are Peak and Valley Values Important?

What are Peak and Valley?

In industrial tests and dynamic processes, the highest (Peak) and lowest (Valley) values observed during that process are often more important than the instantaneous value. However, these values sometimes occur and vanish within milliseconds.

Application Examples

1. Tensile Test: When establishing the breaking point of a material, you want to know the maximum force (Peak) at the moment of rupture. A standard display might miss that instant.
2. Impact Test: The peak of the shockwave created by a hammer strike.

Peak Hold Function

Amazeng ZMA Series devices measure 1000 times per second to capture and hold these microsecond peaks in memory. Even if you, as an operator, look at the screen and miss that instant, the device can tell you "The highest value seen was 540.2 kg".
