display and microprocessor technology to meet the requirements
of two-wire and three-wire test resistance.
Suitable for
telecommunications,
electricity,
meteorology,
computer
rooms, oil fields, power distribution lines, iron tower
transmission lines, gas stations, factory grounding networks,
lightning rods and so on. Instrument testing is precise, fast,
simple, stable and reliable
.
The
digital grounding resistance tester
is controlled by the
microprocessor and can automatically detect the connection status
of each interface and the interference voltage and interference
frequency of the ground network, and has the function of testing
the auxiliary grounding resistance value. At the same time store
500 sets of data,
resistance measurement range: 0.01
