Here only as a supplement Another negative point: The display of minimum and maximum measured values within a measurement period is not working. There are instead displayed only current values. That means you will turn off the consumer, fall in the Max display, previously observed values to 200W, to 0. It's the same with the min values for example when switching on consumers. The function described is not made by the instrument and should be deleted from the product description. Therefore only 2 star.
