To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
Mine came in a small unpadded box inside a bubble wrap envelope. The bubble wrap has a 6 inch slash through it, but miraculously, the unit was undamaged. I suppose it was packed well enough IF you trust your courier not to slice or crush small items Tested against my fluke179: Frequency was right on at 25.00Hz and 500Hz. Volts was within 10mV from 2V to 10V. mA was 0,13mA low across the range. ( I haven't explored adjusting) . It only acts as a mA source. It can't simulate a 2 wire 4-20 transmitter. The user interface is easy to figure out. Some of the display text is about as small as can be. I wouldn't put this into industrial or calibration service, but for a light-duty function generator for functional tests, it's great value if it arrives intact.
