ZOYI ZT-XT1 Transistor Tester and True RMS Multimeter
A professional 2-in-1 diagnostic instrument for testing electrical circuits, transistors, semiconductors and electronic components without carrying separate devices.
Multimeter and Component Tester in One Device
The ZOYI ZT-XT1 combines a True RMS digital multimeter with an intelligent transistor and component tester. It is designed for electronics engineers, repair technicians, workshops, laboratories and advanced DIY users who need both circuit measurement and component identification.
The component-testing mode supports compatible BJT transistors, MOSFETs, IGBTs, diodes, Zener diodes, resistors, capacitors and inductors. Automatic identification helps determine the component type, pin arrangement and available electrical parameters.
A complete diagnostic workflow: Identify and evaluate individual electronic components using the smart tester, then use the True RMS multimeter functions to investigate voltage, current, resistance and circuit behaviour.
Smart Component Testing
BJT Transistors
Identifies compatible NPN and PNP devices, pin layout and transistor gain.
MOSFET and IGBT
Supports identification and basic parameter testing of compatible devices.
Diodes and Zener Diodes
Checks diode direction, forward voltage and supported Zener voltage.
Capacitance and ESR
Measures capacitor value and equivalent series resistance where supported.
Resistance
Measures compatible resistive components across a wide measurement range.
Inductance
Measures compatible inductors during component selection and diagnostics.
True RMS Electrical Measurement
In multimeter mode, the ZT-XT1 provides AC/DC voltage, AC/DC current and resistance measurement for circuit testing, electrical maintenance and electronics troubleshooting.
True RMS technology: True RMS measurement supports dependable AC readings on non-linear and distorted signals produced by switching power supplies, LED drivers, inverters and other modern electronic systems, within the meter’s specified limits.

Recommended Applications
Electronics Repair
Suitable for PCB troubleshooting, semiconductor testing and component-level diagnostics.
Workshop and Laboratory
Ideal for engineers, repair benches, service departments and technical maintenance.
DIY and Education
Useful for students, hobbyists, electronics projects and circuit-testing practice.
Important testing guidance: Remove components from powered circuits and safely discharge capacitors before using component-test mode. In-circuit connections can influence identification and displayed values. Always use the correct terminals and observe the instrument’s marked voltage, current and measurement-category limits.
