When NOT to use a LoZ Meter

LoZ meters are valuable tools for identifying ghost voltages and compromised voltage sources that exhibit high impedance upstream. When troubleshooting AC mains circuits, it is generally recommended to use the LoZ mode. This mode introduces a load at the test point, which proves advantageous because the circuits being tested are typically of low impedance compared […]
