Connect 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 Tester.
•
Connect the common test lead before the live test
lead and remove the live test lead before the
common test lead.
•
Before and after testing, confirm that the Tester
does not indicate the presence of a hazardous
voltage, see Figure 4. If the Tester beeps
continuously and a hazardous voltage is shown
on the display, remove power from the circuit
under test and disconnect test leads.
