NST NEUTRAL AND SUPPLY TESTER

Meter installers use the NST Tester when placing smart meters on domestic and commercial switchboards. The Dewar NST Tester indicates a safe or unsafe condition by measuring voltage as well as impedance in relation to the connected active, neutral and reference earth.

The M1120-v2 unit is for performing Neutral & Supply Testing as outlined in the VESI Installation Supply Connection Tests & Procedures Manual.

Use the NST Tester to ensure the incoming active and neutral power connections have been correctly identified and are safe to use before reconnecting the main power.
