Why choose it

The EX530A combines high accuracy (±0.1% basic DC voltage) with advanced troubleshooting features. LoZ mode eliminates ghost voltages, LPF filters out inverter noise, and NCV quickly detects live wires. Its 40,000 count resolution reveals small signal changes that lesser meters miss.

Ideal use cases

• Industrial electrical maintenance
• HVAC system diagnostics
• Variable frequency drive (VFD) testing
• Field service and commissioning

Good to know

The meter supports optional PC connectivity via USB for data logging and analysis. It runs on a single 9V battery and includes a backlit display for low-light work.
