▲ AC string detection function, the instrument can judge the AC string fault in the DC system, and can measure the AC voltage value in the DC system. The AC voltage measurement range is 0~280V.

▲ Branch circuit insulation resistance measurement function, the instrument measures the positive and negative insulation resistance of each branch circuit to ground.

▲ The branch circuit ground fault point location function, the instrument can realize the ground fault branch circuit ground fault point location function.

▲ With ammeter function, the device can be used as a high-precision ammeter, and the current measurement resolution can reach 0.01mA.

▲ It has the function of non-signal grounding search. The device can locate the ground fault point without injecting any signal into the system.

▲ Direction display function. For branch circuits with grounding indications tested, the instrument will have direction indication arrows to remind users of the relative direction between the grounding point and the grounding point being searched, which improves the search efficiency.

▲ Insulation index analysis function. When using the grounding function to detect, after detecting a branch, the detector will display the insulation index of the branch for the user's reference and analysis.

▲ Wave curve display function. When using the detector to detect the insulation condition of the branch under test, the display will display the current change of the branch under test in the form of a wave curve, which is convenient for users to find fault points quickly and accurately.
