Connecting to the Circuit Under Test

To avoid possible electric shock or personal injury:
• Remove all power from the circuit under test and discharge circuit
capacitance before testing a circuit with the Meter.
• Connect the test leads to the Meter inputs before connecting to the
circuit under test.
• Before and after testing, confirm that the Meter does not indicate the
presence of a hazardous voltage at the terminals. If the Meter beeps
continuously and a hazardous voltage is shown on the display,
disconnect test leads and remove power from the circuit under test.
To connect to the circuit under test:
1. Rotate the safety shutter to expose the terminal connections.
2. Insert the test leads in the terminals shown (Figure 8), and connect the test
leads to the circuit under test.
