The OIHVP15HF is a high voltage probe with an input resistance of 100MΩ, a maximum working voltage of 15KV DC, 10KVrms, and 30KV peak. The accuracy is ±3% for DC volts and ±3% for AC volts. The bandwidth is 50MHz.
The OIHVP15HF and OIHVP40 are high‑voltage probes designed for use with oscilloscopes to measure up to tens of kilovolts safely. The manual details the electrical characteristics, cable length, and environmental limits for each model.
Key sections cover safety precautions such as grounding the probe before contact, turning off the high‑voltage source when possible, and proper cleaning. Operational steps describe connecting the probe to the oscilloscope, selecting the appropriate voltage range, and interpreting the divided voltage reading. This manual is written in Chinese.
