Important tips:
1. Power supply requirement: AC50Hz, 220V, stability of frequency: fluctuation less than 0.5%
2. When using it, the capacitance of the sample should not exceed the rated capacity of the instrument. The over low capacitance of the sample will affect the output wave form. If the capacitance is less than 0.05μF, the instrument cannot output normally. In this situation, the tester needs to have a 0.05μF compensation capacitor(provided by our company) in parallel connection as an auxiliary output when the sample’s capacitance is less than 0.05μF.
3. When using it, it is prohibited to boost voltage without load, or to connect with resistive load
