User manual IDEAL 320 CONTRACTOR GRADE MULTIMETER

[. . . ] Before beginning all unknown measurements, set meter to highest possible range. Before breaking a circuit for testing, turn off the power to the circuit. When disconnecting from a circuit, disconnect the hot lead first, then the common lead. Disconnect the meter from the circuit before turning off any indicator, including motors, transformers, and solenoids. 2 2 1 5 3 4 1.
