Product-specific buyer note

Require order code IR4056-20 on the unit, carton and GST invoice because IR4056-21 has a different lead bundle and conformity status. The exact India route did not expose a dependable current price, so confirm a tax-inclusive serial-linked quote, physical stock, calibration certificate, accessory bundle and India warranty in writing. Crucially, Hioki's 2 March 2026 notice identifies 98 affected serial-number units across several IR405x models shipped from March 2025 through January 2026, including some IR4056-20 units. Check the unit's serial against Hioki's published list before acceptance; an affected unit must receive Hioki's free re-adjustment before reliance on its readings.

India regulatory note

Insulation testing intentionally generates hazardous DC voltage. Isolate, lock out, prove dead, discharge stored energy and use trained personnel with correctly rated leads and PPE. Never test a live circuit or touch the circuit until automatic discharge has completed. CAT III 600 V is conditional, not a blanket permission for all installations. Verify the serial-specific March 2026 re-adjustment notice, calibration status and applicable Indian electrical-safety procedures before using results for compliance or safety decisions.
