- The COMPASS Pro device should be used only by trained and qualified personnel.
- Always adhere to proper high-voltage electrical safety practices.
- Extreme humidity may decrease the voltage/current detection range.
- Before field use, always confirm that the COMPASS Pro device is powered on, connected to a mobile device, and working (as indicated by the center light blinking green every 5 seconds), and test with a known source of voltage/current.
- Always test and verify that the sensitivity settings on the COMPASS Pro device are appropriate for the workspace environment.
- Some materials may shield electromagnetic fields from the detection circuits of the COMPASS Pro device.
- Always verify that a potential voltage source is de-energized before making contact.
- The COMPASS Pro device should only be used as a secondary voltage detection method
