• Use extreme caution when you work with voltages above
40V. Always disconnect power from the circuit you are
measuring before you connect test probes to high-volt-
age points.
• Never connect the test probes to a source of voltage
when you select the Rx1K W or 150mA DC function.
• Always discharge filter capacitors in the power supply of
the circuit under test before you attach test probes.
• Always turn off power and disconnect the test leads
before you replace the batteries.
