ZadPad- handheld flicker meter with touch display for SVM, PstLM and much more.

Flicker measurement of light is becoming increasingly important. Especially because light flickering can have negative effects on humans and animals (animal husbandry). And it is especially due to LED technology that this topic is increasingly moving into the focus of attention. Corresponding standards have been and are still being developed (IEEE1789 for the USA, and CIE is also working diligently on limit values and calculation methods).

While flicker%, flicker index and flicker frequency were previously known parameters in the time domain, the new calculation methods (e.g. SVM) require evaluations and representations in the frequency domain.

Now available: The all-rounder can do more than just flicker%, IEEE1789 and SVM

Currently there are several parallel evaluation methods such as flicker%, IEEE 1789, PstLM or SVM and more complex evaluation methods are expected in the future.

The ZadPad is a handheld measuring device for a wide variety of measurement variables depending on the attached sensor. The measurement signals from the sensor can be analyzed in an oscilloscope display or as a frequency spectrum. This information can be stored on the internal USB drive.

The sensor responsible for flicker measurement has a V(Lambda) sensitivity, the measured values can be evaluated according to PstLM, SVM, Flicker%, Flicker Index and much more.

High accuracy due to high sampling rate

The Zadpad achieves high measuring accuracy by using a V(lambda) photodiode in connection with a sampling rate of up to 1.8 MHz with 16 bit resolution. This means that dimmed light can be detected even with a high PWM frequency.
This high measurement accuracy also makes the ZadPad ideal for measurements in the laboratory and development and is indispensable for manufacturers of lamps / lights and LED control gear.
