Description
The ERT 300 system is the reference tool for players wishing to know the tension of their string. Indeed, thanks to micro-impulses, the ERT 300 can determine the dynamic tension of your string, which you can then convert into kilograms to find the tension of your racket. This tool is the most used by professional stringers on the circuit.
Very simple to use, the ERT 300 must be positioned on the three widest main strings using its small claws. The device will then send micro-impulses to determine the dynamic tension of the string, this value is expressed in DT.
Thanks to the provided chart, you can easily convert this data into kilograms or pounds.
Warning, the tension measured coming out of the stringing machine may differ from that chosen on the machine depending on the stringer's skill level.
The ERT 300 operates with two CR2032 batteries supplied.
