KOOCU DT-9205 Plus Fully Automatic Digital Multimeter

KOOCU DT-9205 Plus Fully Automatic Digital Multimeter

The KOOCU DT-9205 Plus is a popular, entry-level handheld digital multimeter known for its large adjustable LCD and comprehensive measurement ranges. Despite being marketed as “fully automatic” in some retail listings, it is a manual-range meter, meaning you must rotate the dial to the specific range you intend to measure.

The “Plus” model typically features enhanced overload protection and a more rugged IP67-rated casing compared to the standard DT-9205A.

Technical Specifications

Key Functions & Features

• Transistor Test (hFE): Can measure the gain of NPN and PNP transistors (0–1000).

   

• Diode & Continuity: Includes an audible buzzer that sounds if resistance is below approximately 70Ω.

   

• Auto Power Off: Automatically shuts down after ~15 minutes of inactivity to save battery.

• Data Hold: Features a “Hold” button to freeze the current value on the screen.

   

• Induction Pen (NCV): Some “Plus” iterations include a non-contact voltage (NCV) sensing function for detecting live wires behind walls.

Safety Tip: Always ensure your test leads are in the correct ports—especially when switching from Voltage to 10A Current measurements—to avoid blowing the internal 0.5A or 10A fuses.
