AL603  Ground network grounding resistance tester

Implementation of standards:

DL/T845.2-2004 

 

Net test through the ground of several years research, we according to lately national standard develop succeed a few new connect a ground of resistance test instrument. This several techniques which test an instrument lead, the function is overall and have etc. effect good, test accuracy Gao, the anti- interference's ability be strong, weight lightly etc. characteristics, the spot usage the customer reflect very good.

 

Function characteristics

1, the work Pin measure etc. effect good. Testing electric current wave a form is a sine wave and the frequency only differs a 5 Hzs with work Pin and use a 45 Hz and 55 Hz two kinds of frequencies to carry on diagraph.

2, the anti- interference's ability be strong This instrument adopts a different Pin method diagraph, match with modern and soft hardware to filter a technique, make the instrument have very high nti- interference function, the test data stabilize credibility. Only bring 0.005 Ω error margins at the 15 V work Pin interference.

3, accuracy Gao. Can use to test to connect a ground of resistance pimping largely net.

4, the function be strong. Can measure related standard to rule of connect all characteristic parameters of a ground of device.Can not only measure to connect a ground of resistance, but also can measure an electric resistance weight and the electricity anti- weight.

5, can measure the spot interference, convenient customer estimate measure error margin.

6, the operation be simple. Whole Chinese menu type operation, directly display to measure a result.

7, can keep 50 sets of diagraph dates, and can print to measure a result on the scene from taking a miniature printer.

8, the cloth line labor quantity be small, didn't need big electric current line.

9, this instrument physical volume be small and the weight be light and the convenience take.

Technique index sign

1, the resistance measure scope:0~200 Ωs

2, resolution:0.001 Ωs

3, measure an error margin:±(read few ×s 1%+0.005 Ωs)

4, the electric voltage interference of the anti- work Pin 50 Hz ability:15V

5, test electric current wave a form: Sine wave

6, test electric current frequency:45 Hz, 55 Hz dual-band

7, biggest output electric current:1A

8, biggest output electric voltage:100V

9, measure a line request: The electric current line copper Xin cuts the area ≥ 0.5 mms 2

The electric voltage line copper Xin cuts the area ≥ 0.2 mms 2

10, power supply power supply: The AC220 V ± is 10%, 50 Hz

11, use environment: Temperature:-10 ℃s 40 ℃ ;Relative humidity:<90%
