because I got not supplied the ordered part (3 connectors and indicators with housing). Mine had only 2 ports and not the cabinet / frame - front panel mounting thus not so easy. (Return worth at the price eh) For the supplied block I deposited photos. My "measuring devices" were: A multimeter with digital display (uncalibrated) and a power supply unit "Statron" relatively accurate analog display. My measurement results to the component shown in the image: - Because there is no auxiliary voltage is present, the full display brightness is reached at about 4 volts before, there are already quite correct voltage display - I could recognize what at 2 volts - The accuracy of one digit (ie, approximately 0.1 volts), I can attest - even rounding up works great (I have two decimal places measured) - Is the current consumption during operation is between 5 V and 30 V 17 mA - that is consistent with the product description in accordance - The display color is yellow and as described Actually, the product would have to get 5 points - but since it is not the ordered, I give only one point, regardless of my test results
