1.2. A Word about Safety
Measurement category II is for measurements performed on circuits connected to the low voltage
installation. This multimeter is designed to ensure the safest operation possible. However, safe
operation depends on the operator. Make sure to follow these simple safety rules:
• Never apply a voltage to the multimeter that exceeds the limits given in the specifications.
Never apply more than 600VDC or VAC RMS between an input jack and ground.
• Use extreme caution when working with voltages above 60VDC or 30VAC RMS.
• Always discharge filter capacitors in the power supply circuit under test before you attach test
leads.
• Never connect to a source of voltage when you select the DCA, resistance measurement.
• Always turn off power and disconnect the test leads before you replace the batteries or fuse.
• Never operate the multimeter unless the battery cover is in place and fully closed.
• When carrying out measurements on TV or switching power circuits, always remember that
there may be high amplitude voltages pulses at test points which can damage the meter.
• Never use the multimeter to measure currents on circuits that contain voltages higher than
240VAC.
