The UNI-T UT207B is a True RMS digital clamp meter designed for measuring AC/DC current and voltage, resistance, capacitance, frequency, and more. It's a robust and versatile tool suitable for various electrical applications.

True RMS Measurement: Provides accurate readings for both sinusoidal and non-sinusoidal AC waveforms.   
AC/DC Current Measurement: Measures AC and DC current up to 1000A.
AC/DC Voltage Measurement: Measures AC and DC voltage up to 1000V.
6000 Count Display: Offers high-resolution measurements.   
Large LCD with Backlight: Ensures clear readings even in low-light conditions.   
42mm Jaw Opening: Allows clamping around conductors up to 42mm in diameter.   
NCV (Non-Contact Voltage Detection): Safely detects AC voltage without physical contact.   
LoZ Mode: Helps eliminate "ghost" voltages for more accurate AC voltage readings.   
LPF ACV (Low Pass Filter for AC Voltage): Useful for measuring the voltage of variable frequency drives (VFDs) and inverters.   
Inrush Current Measurement: Captures the peak current during motor startup or other high inrush events.   
Resistance Measurement: Measures resistance up to 60 MΩ.
Capacitance Measurement: Measures capacitance up to 60 mF.
Frequency Measurement: Measures frequency up to 10 MHz.
Continuity Test: Provides an audible signal when a circuit is complete.
Diode Test: Allows testing of diodes.   
Min/Max Mode: Records the minimum and maximum readings.   
Data Hold: Freezes the current reading on the display.
ZERO Mode: Used for relative measurements.
Flashlight: Built-in flashlight for illumination in dark areas.   
Auto Range: Automatically selects the appropriate measurement range.   
Auto Power Off: Conserves battery life by automatically turning off after a period of inactivity.   
Safety Rating: CAT III 1000V and CAT IV 600V safety ratings ensure user protection.
