Physically measuring real electrical voltages is now possible with this app and the HMB | TEC iDVM measuring adapter.

A prerequisite for the practical use of this app is an additional adapter which is offered by HMB | TEC GmbH under the name "iDVM" with the article number P20200120-1. Please only use the original adapter provided.

The adapter has a measuring tip and a ground cable.
The measuring range is +/- 60 volts DC (VDC) and the resolution 0.1 V (the ADC used in the adapter works internally with a resolution of 12 bits).

The real measured voltage values can be displayed in analog and digital form or as a curve diagram. In addition, the minimum and maximum values are shown in the diagram. To display individual measured values, simply tap on the corresponding measured value in the diagram. To reset the min / max values, press the button labeled "Reset Min & Max" below the diagram.
