The FNIRSI MC-40 is a budget True RMS clamp meter for electricians. Close the jaw around one conductor to read AC current up to 600A without breaking the circuit, then use the test leads for voltage, resistance, diode and continuity checks.
Auto ranging, NCV, data hold, a backlit display and a flashlight cover everyday DB-box and panel work. It runs on two AAA cells and switches itself off after inactivity.
