Load test

Change to the <Load test> in the lower part of the IMIB display.

Press <Start> to start the test for load current and voltage.

During the test, the load current of the USB connection is increased in steps, and the voltage is measured at the USB connection at the same time. These values are shown graphically on the IMIB display and documented in the indication range.

NOTE: The current status of the measurement is displayed and documented in the indication range. In the following graphic the USB voltage is 4.92V with a load current of 500mA .

The green line shows the voltage curve during this load increase.

The red line (1) shows the current requested by the IMIB.
