• Exercise extreme caution when working with voltages in excess of 60Vdc or 30Vrms AC. Keep your fingers behind
the probe barriers while using the device.
• Do not connect the leads to a voltage source while the function switch is in one of the following modes: current,
resistance, temperature, battery, diode, transistor or continuity.
• Disconnect all test leads from the circuit to be tested prior to selecting a different function or range.
• Do not use the meter in dusty environments or in the presence of flammable gases and steam.
• Have the device checked by a qualified technician in case of malfunction.
