Features:
1，Multifunctional measurement mode, voltage and resistance can be selected. Gears can be selected.
2，Wide range of applications: suitable for power, communication, post and telecommunications, railways, mines and other fields
3， Variety of measurement methods can be adopted, including two-wire and three-wire measurement. The accuracy can reach 0.001 Ω.
4，The measurement time can be set. There is no automatic shutdown function for 10 minutes, which is more durable.
5，Easy to operate: the package comes with measuring AIDS and instructions.
