FAQ Questions and Answers

1. What tests can the Megger EVT100X perform on EVs?
   The Megger EVT100X performs essential EV testing including insulation resistance, low resistance bonding (DLRO), continuity, DC voltage measurement, diode testing, and temperature measurement with compensation. It also supports advanced insulation diagnostics such as PI and DAR, making it suitable for high‑voltage EV system testing and maintenance.

2. Does the EVT100X support automatic temperature compensation for insulation tests?
   Yes. The EVT100X supports temperature measurement and compensation, allowing insulation resistance results to be adjusted for more accurate and consistent readings under varying conditions. It also features a guard terminal to minimize the influence of surface leakage current on measurements.

3. How do I download the 256 stored results?
   Results can be exported via a USB stick inserted into the device.

4. What is the difference between the EVT100 and EVT100X?
   The EVT100X includes Bluetooth connectivity for real-time data streaming, storage, and reporting, while the EVT100 offers the same core EV testing functions without wireless communication features.
