Named standards and a low-pass filter
Two trade instruments, and one listing that goes further than any other on this site.
The DUSPOL digital states that it is tested and approved to DIN EN 61243-3 and VDE 0682-401:2015. No other listing in this catalog names a standard at all. It also indicates from 50 V with flat batteries — removing the failure mode where a dead cell makes a live circuit look dead.
The P2 mini clamp publishes a low-pass filter at approximately 160 Hz, which is what makes a reading on a switched motor drive mean anything.
The clamp publishes four specifications and no category, which is terse for a trade instrument at the top of its hub.
The DUSPOL, for the flat-battery behavior. It is the difference between an instrument that degrades and one that lies.
1–1000 V AC / 1200 V DC · True RMS · tested to DIN EN 61243-3, VDE 0682-401
The only tester here that names the standard it is approved to: DIN EN 61243-3 and VDE 0682-401:2015, with a 1–1000 V AC and 1200 V DC range and indication from 50 V even on flat batteries.
Best for: Photovoltaic, industrial and hybrid-vehicle work, where 1200 V DC is real and the approval matters.
400 A True RMS · inrush · low-pass filter ~160 Hz
A trade mini-clamp reading load currents to 400 A with true-RMS, an inrush function and a low-pass filter at around 160 Hz for suppressing the switching noise of motor drives.
Best for: Motor and lighting installations where the drive noise is the reason previous readings made no sense.
