Major Tech 1000V AC/DC Voltage Tester with LCD – MT478

Perform two-pole voltage measurements and digital circuit testing with the Major Tech 1000V AC/DC Voltage Tester (MT478). Designed for electricians, electrical inspectors, and plant maintenance engineers, this 2-pole tester measures AC and DC voltages up to 1000V while featuring a 2000-count LCD screen alongside standard LED level indicators. Equipped with resistance testing up to 1999Ω, RCD trip testing, and tactile vibration feedback, it delivers reliable diagnostics for industrial distribution boards and panel maintenance.

Key Features:

• Dual Digital & LED Display: Features a 2000-count LCD screen for exact digital readouts alongside stepped LED voltage indicators up to 1000V AC/DC.

• Safety Category Rating: CAT IV 600V and CAT III 1000V safety rating for industrial environments.

• Switchable Load & RCD Testing: Dual pushbutton switchable load (30mA @ 230V) tests RCD operation and suppresses ghost voltages.

• Resistance Measurement: Measures low resistance values up to 1999Ω directly on the LCD screen.

• Rotary Field Indication: Pinpoints 3-phase rotary field direction and tests 400V phase rotation for motor connections.

• Tactile Feedback & Torch: Built-in vibration function signals load states, paired with an integrated flashlight for dark switchgear panels.

Detailed Description:

The Major Tech MT478 combines the immediate visibility of a two-pole LED voltage indicator with the digital precision of a multimeter screen. With a fixed impedance of ~200kΩ (≤ 3,5mA @ 1000V), it protects operators against accidental high-energy faults while testing live conductors.

Equipped with 4mm probe tips, tactile vibration under load, and phase rotation testing, the MT478 simplifies industrial troubleshooting, panel testing, and circuit isolation procedures.
