2. Safety
Safety Notes
•Before operating the device, you must read, understand, and follow all instructions, dangers,
warnings, cautions, and notes.
•FLIR Systems reserves the right to discontinue models, parts or accessories, and other items, or to
change specifications at any time without prior notice.
•Remove the batteries if the device is not used for an extended period.
Warning Statements
•Do not operate the device if you do not have the correct knowledge. Formal qualifications and/or
national legislation for the electrical inspections can apply. Incorrect operation of the device can
cause damage, shock, injury or death to persons.
•Do not start the measuring procedure before you have set the function switch to the correct
position. This can cause damage to the instrument and can cause injury to persons.
•Do not change to resistance when you measure the voltage. This can cause damage to the
instrument and can cause injury to persons.
•You must disconnect the test leads from the circuit that you did a test on before you change the
range. If you do not do this, damage to the instrument and injury to persons can occur.
•Do not replace the batteries before you remove the test leads. This can cause damage to the
instrument and can cause injury to persons.
•Do not use the device if the test leads and/or the device show signs of damage. Injury to persons
can occur.
•Be careful when you do the measurements if the voltages are more than 25 VAC rms or 35 VDC.
There is a risk of shock from these voltages. Injury to persons can occur.
•Do not do diode, resistance, or continuity tests before you have removed the power from
capacitors and other devices under test during a measurement. Injury to persons can occur.
•Do not use the device as a tool to identify live terminals. You must use the correct tools. Injury to
persons can occur if you do not use the correct tools.
•Make sure that children cannot touch the device. The device contains dangerous objects and small
parts that children can swallow. If a child swallows an object or a part, speak with a physician
immediately. Injury to persons can occur.
•Do not let children play with the batteries and/or the packing material. These can be dangerous
for children if they use them as toys.
•Do not touch expired or damaged batteries without gloves. Injury to persons can occur.
•Do not cause a short-circuit of the batteries. This can cause damage to the instrument and can
cause injury to persons.
•Do not put the batteries into a fire. Injury to persons can occur.
