Preis_Leistung OK! Dokumentation eine Katastrophe !

parfait

Dés la mise sous tension, 7 traits horizontaux s'affichent sur la rangée de digits, ce qui atteste d'un fonctionnement correct sans signal sur l'entrée, ou un signal hors fréquences limites ou une tension d'entrée insuffisante (environ 1 à 2 volts).L'inverseur de mode :Position [ O ] affiche la fréquence en HertzPosition [ I ] affiche le durée de la période en micro secondes.Je l'ai encastré sur un fréquencemètre qui ne possédait pas d'affichage de la fréquence.

This is an excellent product and currently at a very reasonable price. The quality of the PCB is excellent, as good as any used in professional equipment. The Meter comes as a kit, and components need to be soldered. The number of components is not large but some soldering skill is required, but with a bit of care it can be done easily and quickly even by those with only elementary soldering skills. I used a soldering iron with a pointed tip and run it hot (400 deg C) so that the solder melted quickly, minimising each component exposure to heat. I used thin solder wire (about 2 mm diameter). The frequency Meter works very well, I tested it up to 100kHz, and a quick comparison with another frequency meter (different make) showed that it was reasonably accurate. The red switch toggles between measuring of frequency to measuring of period in microseconds. The transparent case is easy to assemble and is held together with four of the screws provided. All in all an excellent product, currently at a very reasonable price, and I recommend it.
