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 of time.

FLIR CM174 USER MANUAL Document Identifier: CM174-en-US_AC

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 current or resistance when you measure the voltage. This can cause

damage to the instrument and can cause injury to persons.

Do not measure the current on a circuit when the voltage increases to more than 1000 V.

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 taking 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.

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.

Cautions

Do not use the device for a procedure that it is not intended for. This can cause damage to the

protection.
