- Resistance: Measurement up to 200MΩ
- Capacitance: Measurement up to 100mF
- Frequency/Duty Cycle: Up to 10MHz
- Temperature: -50°C to 1000°C (-58°F to 1832°F)
- Continuity: Fast-response audible indicator with minimal lag
- Diode Test: Forward voltage display with audible indication
- Non-Contact Voltage Detection: With visual and audible alerts
- Live Wire Identification: Using single-probe testing mode
The auto-ranging function works efficiently, quickly selecting the appropriate range for measurement without requiring manual adjustment.
Special Features
A few features that stand out and add significant value:
- True RMS Measurement: Essential for accurate AC measurements, especially in environments with inverters, variable frequency drives, or other non-linear loads.
- MAX/MIN/AVG Recording: Allows tracking of fluctuating signals over time.
- Data Hold Function: Freezes the current reading on display, useful when taking measurements in hard-to-reach areas.
- NCV (Non-Contact Voltage) Detection: A safety feature that detects AC voltage without physical contact.
- Automatic Backlight Color Change: The display backlight turns orange when measuring voltages above 80V AC, serving as a visual safety warning (though some users noted they would prefer this threshold to be set at the industry-standard 30V).
