M-800P DC in AC Clamp Tester

The world first clamp tester which can detect DC current component in AC circuit


Model 800P is the world’s first clamp meter which can detect small
DC current in AC circuit in addition to general AC/DC current measurement.
By using this clamp meter, DC offset surveillance can be made
easily in the actual fields like as solar inverters, etc. and it is possible
to check if the DC component in AC circuit is less than 1% of
the rated AC current or not, according to the regulation.
