Frequently asked questions
Can it measure DC voltage?
No. The listing specifies AC voltage only, so do not use it to measure DC.
How is it mounted and wired?
Cut a 22 mm round opening in the panel. Because it measures mains-level AC voltage from 20 V to 500 V, wire it with the supply isolated and have it handled by a qualified person.
