Features
Low voltage mode (24V AC ~ 1000V AC)
Suitable for testing low-voltage motor (< 90V), audio systems, arc
welding machines, underground mine lighting, cables with thick
insulation layer, and other weak electromagnetic AC signals.
High voltage mode (90V AC ~ 1000V AC):
For detecting urban electric supply and three-phase systems. For
example, power distribution units, electrical panels, and electrical
appliances.
Safety
Warning
1. Please carefully read and fully understand the warnings and
operating instructions before use.
2. Please test the detector on a known live source within the rated AC
voltage range before use.
3. If the detector appears damaged or is not working properly, stop
using it immediately.
4. Do not detect voltage higher than 1000V.
5. Use caution when measuring AC voltage higher than 30V.
6. There may still be voltage even when no acousto-optic alarm is on.
7. The insulation type, wire thickness, distance from voltage source,
shielded wire, other wires, socket design, and other factors may
adversely affect test result. If there are uncertainties, use other
methods to verify the voltage.
