Ecm Industries Llc GDT-3190 Digital Multimeter 500VAC 600VDC

Product Description

The ECM INDUSTRIES LLC GDT-3190 is a 4-function, manual ranging digital multimeter designed for general electrical testing in residential and light commercial applications. It measures AC voltage up to 500 volts, DC voltage up to 600 volts, resistance up to 2 megaohms, and current up to 10 amps. The unit ships with test leads, an instruction manual, and a battery, so it is ready to use out of the box. A protective rubber boot surrounds the meter body to absorb impact from drops and to secure the test leads during storage and transport. CULUS approval confirms the meter meets recognized safety standards for electrical test equipment.

This multimeter is suited for HVAC technicians, electricians, plumbers, and pool service professionals who need a reliable handheld meter for quick field diagnostics. Typical applications include verifying supply voltage at disconnect boxes, checking DC control circuit voltage, testing component resistance such as capacitors, contactors, and solenoid coils, and measuring current draw on single-phase circuits. The manual ranging design gives the technician direct control over measurement range selection, which is useful in environments where auto-ranging may not match workflow preference.

Installation Notes

This meter is a handheld test instrument, not an installed component. Always de-energize and lock out the circuit before making resistance or continuity measurements. When measuring live voltage, confirm the meter is set to the correct function and range before connecting test leads to the circuit. Use in accordance with NFPA 70E safe work practices and local electrical codes.
