provides that the electrical conductivity should use special
instruments to measure. The instrument resolution is 1mΩ;
accuracy is not less than 1.0 class. Based on this standard, our
company designed this high degree of automation and portable
tester. It is specially used to test the electrical integrity of earthing
device; its technical specification has reached or exceeded the
relevant standards. The instrument is characterized by simple
operation, high accuracy, fast test speed, good reproducibility, and
intuitive readings. It is an ideal special instrument that meets the
requirements of regulations and standard.
II. Functions
The instrument is suitable for measuring on-resistance value
between electrical equipment grounding down-lead and earth mat
(or adjacent devices). It also applies to measure low-value resistor.
III. Features
(1) Power technology: For latest power supply technology, the
instrument outputs 10A current and can continuously work for a
long time which overcomes the weakness of instantaneous current
produced by pulsed power. It can effectively puncture the oxide
layer of the switches and then get precise results.
