1.True RMS Measurement
Provides accurate readings for non-sinusoidal AC signals, ensuring reliable performance in industrial and electronic applications where waveforms may be distorted.
2. High-Precision 3½-Bit Display
Maximum display of 1999 counts delivers clear, stable readings with high resolution for precise measurements in both professional and hobbyist use.
3. NCV (Non-Contact Voltage) Detection
Enables safe and quick voltage detection without physical contact, ideal for troubleshooting wiring and identifying live circuits.
4. REL (Relative Value) Mode
Allows users to zero out test lead resistance or set a reference value, making it easier to measure small changes or compare differences.
5. Data Hold & Backlit Display
HOLD function freezes readings for easy recording, while the bright backlit screen ensures visibility in dimly lit or dark environments.
6. hFE Transistor Test
Supports both NPN and PNP transistors, enabling quick gain testing for semiconductor troubleshooting and component matching.
7. Multiple Measurement Ranges
Covers voltage (up to 1000V DC / 750V AC), current (up to 20A), resistance (up to 20MΩ), frequency, and capacitance, making it a versatile tool for various electrical tasks.
8. Overload Prompt & Auto Power-Off
Overload indicator alerts users when input exceeds the range, preventing damage. Auto power-off conserves battery life after periods of inactivity.
9. Robust Safety Ratings
Rated CAT III 600V / CAT II 1000V, ensuring safe operation in distribution-level and mains-connected environments with enhanced protection against transient voltage spikes.
10. Built-in Test Leads & Input Protection
Multiple input jacks with clear labeling reduce connection errors, and internal fusing on current inputs adds an extra layer of safety during high-current measurements.
