posed metal pipes, outlets, fixtures, etc., which might be at ground potential. Keep your
body isolated from ground using appropriate methods.
• Disconnect the test leads from the meter before making current clamp meas-
urements. This reduces the risk of electric shock.
• When measuring resistance, disconnect all power (remove batteries, unplug
cord, discharge all capacitors, etc.) to the circuit being measured. This reduces
the risk of electric shock.
• After resistance test, the capacitive circuits must be discharged. This will help
protect against electric shock.
• Use extreme caution when working near bare conductors and bus bars. Acci-
dental contact with conductors could result in electrical shock.
• Turn OFF power to the circuit under test before cutting, unsoldering, or break-
ing the circuit. Small amount of current can expose the operator to a shock hazard.
