F404T AC/DC PHOTOVOLTAIC CLAMP METER
A built-in self-test that checks your clamp before you trust it. So, you know for certain, not just probably, that a circuit is safe to open.
The real challenge?
Ensure the absence of current – not just voltage.
Zero DC current. Verified, not assumed.
Opening a live DC circuit can trigger a powerful, dangerous electric arc.
Most disconnection points on a PV system are “live disconnectors” – meaning they’re opened while current may still be flowing. You’ll find this on:
- MC-type connectors
- Most fuse boxes
- Any opening device activated with a tool
That’s exactly why confirming zero current, not just zero voltage – matters before you touch any of these. To open or operate these devices safely, the circuit has to be de-energised first.
The problem? A faulty, malfunctioning, or misconfigured clamp can still display “0.00 A DC” – even when it isn’t.
Not with the F404T. Its patented Auto check confirms the reading is real before you trust it.
The F404T guarantees reliable DC power-off verification.
THE RISK
Lockout/tagout on PV systems mean checking there’s no current, not just no voltage. A standard clamp that’s misconfigured or faulty can still show zero – even with current flowing. This can give a false sense of safety when it matters most.
THE SOLUTION
The F404T carries a patented, Auto Check function. Press one button, and the clamp generates a known reference current, checking its own reading before you trust it to confirm a circuit is safe to open.
2-IN-1 MEASURING DEVICE
Does more than running a safety check. The F404T is a multifunction clamp meter you’ll reach for – every job.
