Wiseup Digital Test Pen 040903
. Voltage Range : DC 12V / AC 220V - 250V
. This a battery-free electrical testing tool used to measure AC/DC voltage segments and verify circuit integrity.
. It does not show a dynamic real-time value like a standard multimeter. Instead, it displays incremental voltage benchmarks : 12V, 36V, 55V, 110V, and 220V.
. The highest number displayed on the screen indicates the active voltage of the source.
