| Power frequency: 50Hz ± 0.5Hz | Power supply voltage: 220V ± 5V | |
| measuring range | In-phase component (%): 0.0001-200.0 | Resolution: 0.0001 |
| Orthogonal components (fractions): 0.001-700.0 | Resolution: 0.001 | |
| Impedance (Ω): 0.0001-20.0 | Resolution: 0.0001 | |
| Admittance (ms): 0.0001-20.0 | Resolution: 0.0001 | |
| Basic error | in-phase | Δ X=± (X × 2%+Y × 2%) ± Dx (with 1 level optional) |
| Quadrature Component | Δ Y=± (X × 2%+Y × 2%) ± Dy (with 1 level optional) | |
| X "," Y "- instrument display values | ||
| Dx, Dy "- Quantification Error of Instruments | ||
| Dx=2，Dy=5 | ||
| dial indicator | Level 2 (with Level 1 optional) | |
| scope of work | electric current | (1%～149%)In (In =5A) |
| (5%～149%)In (In =1A) | ||
| voltage | (5%～149%)Un (Un =100V，150V，100V/) | |
| (5%～149%)Un (Un =100V/3) | ||
| Workload | electric current | To TX ＜ 0.12 Ω cos Φ=1 |
| voltage | A for x<0.25VA (100V) | |
| Polarity error indication | When the working current (voltage) reaches more than 5% of the rated current (voltage) and the error exceeds 180%, there should be a polarity indication. | |
| Attention: If the polarity indication still does not appear after exceeding 10% of the rated working current (voltage), it indicates a fault. Please do not increase the current (voltage) again to avoid burning out the instrument. | ||
| Variable ratio error indication | When the working current (voltage) reaches more than 5% of the rated current (voltage) and the error exceeds 30% but is less than 180%, there should be a ratio error indication. | |
| Insulation and voltage withstand tests and instructions | Terminal TX() is connected to the terminal | |
| The power socket can withstand a voltage of 1.5kV and a 1-minute withstand voltage for the casing | ||
