Double insulation
Diode
Dangerous voltage value!
description
This device is a compact digital padlock with 4 digit display
for measuring AC voltage, DC voltage, alternating current,
resistance, continuity diode and temperature. It is easy to
handle and due to its small size it can be always at hand
during a possible measurement.
