When Selecting an Insulation Resistance Tester, Consider the Following Factors: Select Test Voltage Level Based on the Rated Voltage of the Equipment Under Test
Low-voltage equipment (<500V): Select 500V or 1000V range. High-voltage equipment (such as 10kV cables): Typically requires 2500V or 5000V range. Measurement Range: Ensure the instrument's maximum resistance range meets requirements (e.g., whether measurement up to 1TΩ is needed). Functional Requirements: Whether automatic PI/DAR calculation is needed, whether data storage/upload is required.
