The manual provides operation, specifications, and maintenance instructions for the Tonghui TH2810B component parameter tester.
This user manual describes the TH2810B series component parameter tester, which measures inductance, capacitance, resistance, impedance, quality factor and loss angle of components. It includes three models—TH2810B (LCR bridge), TH2618B (capacitance meter) and TH2775B (inductance meter)—and details their shared features, RS‑232C interface, and selectable measurement modes.
The document covers safety warnings, technical specifications, step‑by‑step operating procedures, troubleshooting, accessories, and warranty information. It is intended for qualified personnel who need accurate, high‑speed component testing in production, quality control, or research environments. This manual is written in Chinese.
| Inductance measurement range | 0.01 µH – 99999 H |
|---|---|
| Capacitance measurement range | 0.01 pF – 99999 µF |
| Resistance/Impedance measurement range | 0.0001 Ω – 99999 MΩ |
| Power supply | 220 V ±10 % / 50 Hz ±5 % |
| Power consumption | ≈25 W |
| Relative humidity range | ≤85 % RH (≤80 % RH for accuracy) |
| Measurement speed | Fast ≈15 samples/s, Slow ≈4.5 samples/s |
Before connecting the power cord, verify that the phase, neutral and protective earth conductors are correctly connected and that the earth is securely bonded to ground.
For measurement accuracy the instrument should be used at 18 °C – 28 °C, although it can operate from 0 °C to 40 °C.
Calibration must be performed by qualified personnel; if the EEPROM 28C64 fails, the unit should be returned to the company for service.
