Milwaukee 2239-20, 2238-20 manual Important Safety Instructions, Functions

IMPORTANT SAFETY INSTRUCTIONS

WARNING READ ALL SAFETY WARNINGS AND INSTRUCTIONS.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury, as well as instrument damage and/or damage to the equipment being tested.

Save these instructions - This operator’s manual contains important safety and operating instructions for the MILWAUKEE Clamp Meters. Before using, read this operator’s manual, your battery pack and charger operator’s manual, and all labels on the battery pack, charger and Clamp Meters.

DANGER

Never make measurement on a circuit in which voltage over 1000V exists. Use only leads rated 1000V or better.

Do not attempt to make measurement in the presence of flammable gasses. Otherwise, the use of the instrument may cause sparking, which can lead to an explosion.

Transformer jaw tips are designed not to short the circuit under test. If equipment under test has exposed conductive parts, however, extra precaution should be taken to minimize the possibility of shorting.

Never attempt to use the instrument if its surface or your hand is wet. Do not exceed the maximum allowable input of any measuring range. Only test on unenergized circuits unless absolutely necessary.

Check tool functionality on a known circuit first. Never assume tool is working. Assume circuits are live until they can be proven de-energized.

Do not ground yourself while measuring. Avoid body contact with earthed or grounded sur- faces such as pipes, radiators, ranges and refrigerators.

Never remove the battery pack during a measurement.

This instrument is to be used only in its intended applications or conditions. Otherwise, the instrument's safety functions may not work, resulting in serious personal injury and instru- ment damage.

To reduce the risk of injury from shock and arc blasts, always wear personal protective equipment where live conductors are exposed.

WARNING

Never attempt to make measurement if any abnormal conditions, such as broken case and exposed metal parts are found on the instrument.

Do not rotate the Rotary Dial while the test leads are being connected.

Verify proper operation on a known source before use or taking action as a result of the indica- tion of the instrument.

Do not install substitute parts or make any modification to the instrument. For repair or re- calibration, return the tool to a factory Service/Sales Support Branch or authorized service station.

Do not try to replace the battery pack if the surface of the instrument is wet.

Disconnect all the cords and cables from the object under test and power off the instrument before removing or inserting the battery pack.

Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

Use the meter only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.

When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

Under abusive conditions, liquid may be ejected from the battery, avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

CAUTION

Set the Rotary Dial to an appropriate position before starting measurement. Firmly insert the test leads.

Disconnect the test leads from the instrument for current measurement.

Do not expose the instrument to the direct sun, high temperature and humidity or dew fall. Altitude 2000m or less. Appropriate operating temperature is within -10ºC and 50ºC.

This instrument isn’t dust & water proofed. Keep away from dust and water.

Be sure to power off the instrument after use. When the instrument will not be in use for a long period, place it in storage after removing the battery pack.

Use a damp cloth or neutral detergent for cleaning the instrument. Do not use abrasives or solvents.
