-
Measures DC voltage from 420 mV up to 1000 V.
-
Measures AC voltage (50-500 Hz) up to 1000 V.
-
Measures resistance from 420 Ω to 42.00 MΩ.
-
Measures DC current from 42 µA up to 10 A.
-
Measures AC current in the same range (42 µA to 10 A).
-
Frequency measurement: 0.50 Hz up to 500.0 kHz.
-
-
Terminal Shutter Interlock Mechanism: This restricts which test leads can connect depending on the selected measurement function, helping avoid user error and improving safety.
-
Live-Line Detection: In AC voltage mode, if the device is brought near a live power line (above a certain sensitivity threshold), a buzzer sounds and the display flashes — useful for quick “is this live?” checks.
-
Hold-Auto Function: Automatically records and holds the maximum or minimum measured values (e.g. max voltage or min resistance) for easier reading.
