When discharging, the discharge voltage is measured in real time (the test voltage of the sample is up to 0v).11.Internal rechargeable lithium battery power supply or ac power supply, real ac and dc dual-use does not affect the test accuracy.12.The analog pointer coexists with the digital display, and the number reflects the accuracy of the insulation resistance of the tested product, and the analog pointer can reflect the dynamic change of insulation resistance during the test process.13.Alarm function during voltage boost. The buzzer has alarm function when the device has high voltage output, indicating that there is high voltage output.14.Battery quantity digital display and under voltage alarm protection function.15.Automatic shutdown function: this instrument has automatic shutdown function. It will shut down automatically 10 minutes after the End of measurement.16.Short circuit protection, short circuit state will not burn the instrument.safety warning1.Read and understand the safety warnings and test notes before using the instrument, and pay attention to it during useBefore performing the test, ensure that the product under test has been powered off.2.When the instrument has a high-voltage output, it is forbidden for personnel to touch the tested product and take corresponding safety measures.3.The instrument has an automatic discharge function. For large-capacity samples, manual discharge is required to ensure the safety of operators.4.The instrument must be operated by qualified and professionally trained personnel.5.Please wear insulated gloves before use.6.Do not operate when the surface of the instrument is wet or the hands of the operator are wet.7. Please do not connect the test lead with power.8.Do not touch the circuit under test immediately during or after the measurement, as it may cause electric shock.9.Please stop the test if dirt or carbides that may damage the insulation characteristics are found on the test wire or test port.10. Do not test in flammable places, sparks may cause an explosion.11. If the instrument is abnormal, stop using it. For example: the instrument is damaged or exposed metal parts.12. Please do not install substitute parts or make any unauthorized modification to the instrument. Please contact our company for maintenance.
