Comparison Baxster PS-818-11 vs Baxster PS-818-09

The maximum error (error) in the distance data issued by the parking sensors during operation. Simply put, this is a plus or minus figure that must be assigned to the indicator data in the practical application of the radar (if a digital indication is provided at all, see "Functions / Capabilities"). For example, if an accuracy of 5 cm is specified, then if the display reads 50 cm, the actual distance from the sensor to the obstacle can be anything between 45 and 55 cm inclusive.

Note that there is nothing wrong with the very existence of an error — it cannot be completely eliminated even in the most advanced devices. Therefore, we are only talking about its meaning: the smaller the number indicated in this paragraph, the more accurate the readings of the parking sensors will be. High accuracy is especially important if you have to manoeuvre in very tight spaces where distances often approach the value of the minimum detection distance (see below). In this regard, also note that the claimed error values are relevant only for the operating range of distances.
