Double Clamps Earth Tester is widely used in the fields of
resistance testing for earth resistance of various equipments
and buildings. It also can test the soil resistively and leakage
current of earth systems under different conditions.
It not only possesses the function
of the traditional method but the features of earth resistance
testing without assistant poles, It realizes the on-line measurement
of earth resistance without assistance poles and isolation
of earth devices and equipments by adopting the principle
of 2-poles measurement and the technology of double jaws.
Key Features:
1. Adopt the measurement method in
the type of jaw and meters, can be operated without assistance
poles.
2. Realize the on-line measurement;
it is unnecessary to isolate the earth device from equipment.
3. Test the RMS of leakage current
under the conditions of earth/unearth of system.
4. With the function of self-checking
and avoid the influence for the test result by connecting
the resistance and line resistance.
5. Realize the alternation of functions,
adopt the digital switch to cutover the function in order
to improve the reliability of system.
6. Communicate with the upper-level
PC to realize uploading of the test data which can be saved
and printed easily.
7. Easy and convenient operation with
broad range of usage and measurement, with the backlighting
system.
8. It should test serial.
Safety and environment condition
Electrical safety: It should agree
with the standard of IEC1010-1, EN61010-1 or IP53
