Built In Battery Micro Ohm Meter

1.The whole machine is controlled by a high-speed microcontroller, with a high degree of automation and easy operation.

2.The instrument adopts a brand new power supply technology, with a wide measurement range.

3.The protection function is complete, which can reliably protect the impact of back electromotive force on the instrument, and the performance is more reliable.

4.Fast response speed, stable instrument measurement data, and automatic refreshing of data during the instrument testing process.

5.Intelligent power management technology ensures that the instrument always operates at the minimum power state, effectively reducing internal heating and saving energy.

6.The instrument has a non power-off clock inside.

7.The instrument has a non power-off memory inside, which can permanently store data.

Grounding DC resistance is a necessary test item for semi-finished and finished product factory testing, installation, major repair, change of tap changer, handover testing, and preventive testing by the power department in transformer manufacturing. It can check the welding quality of the winding joints and whether there is a turn to turn short circuit in the winding. It can also check whether the contact at various positions of the voltage tap changer is good, whether the actual position of the tap changer matches the indicated position, whether the outgoing wire is broken, and whether there are broken strands when multiple wires are wound together. This grounding wire resistance tester-also a professional ground continuity tester, earth continuity tester, and ground bond tester-adopts a new power supply technology, which has the characteristics of small size, light weight, large output current, good repeatability, strong anti-interference ability, and complete protection functions. The whole machine is controlled by a high-speed microcontroller, with a high degree of automation and automatic discharge and discharge alarm functions. The instrument has high testing accuracy, simple operation, and can achieve rapid measurement of transformer DC resistance.
