Calibration Information

Safety Information

A Warning identifies conditions and procedures that are dangerous to the user. A Caution identifies conditions and procedures that can cause damage to the Product or the

equipment under test.

XWWarning

To prevent possible electrical shock, fire, or personal injury:

• Use the Product only as specified, or the protection

supplied by the Product can be compromised.

• The battery door must be closed and locked before you

operate the Product.

• Replace the batteries when the low battery indicator ()

shows to prevent incorrect measurements.

• Remove all probes, test leads, and accessories before the

battery door is opened.

• Do not use test leads if they are damaged. Examine the test

leads for damaged insulation, exposed metal, or if the wear indicator shows. Check test lead continuity.

• Do not apply more than the rated voltage, between the

terminals or between each terminal and earth ground.

• Limit operation to the specified measurement category,

voltage, or amperage ratings.

• Do not operate the Product with covers removed or the

case open. Hazardous voltage exposure is possible.

• Do not touch voltages > 30 V ac rms, 42 V ac peak, or 60 V

dc.

• Use the correct terminals, function, and range for

measurements.

• Do not work alone.

• Measure a known voltage first to make sure that the

Product operates correctly.

• Use only cables with correct voltage ratings.

• Use only current probes, test leads, and adapters supplied

with the Product.

• Do not exceed the Measurement Category (CAT) rating of

the lowest rated individual component of a Product, probe, or accessory.

• Connect the common test lead before the live test lead and

remove the live test lead before the common test lead.

Digital Multimeter

Safety Information

• Examine the case before you use the Product. Look for

cracks or missing plastic. Carefully look at the insulation around the terminals.

• Do not use and disable the Product if it is damaged.

• Do not use the Product if it operates incorrectly.

• Do not use the Product in damp or wet environments.

• Keep fingers behind the finger guards on the probes.

• Measure for hazardous voltage without the Low-Pass Filter.

WCaution

To prevent possible damage to the Meter or to the equipment under test, follow these guidelines:

• Disconnect circuit power and discharge all high-voltage

capacitors before you do resistance, continuity, diodes, or capacitance tests.

• Use the correct terminals, function, and range for all

measurements.

• Before you measure current, check the fuses of the Meter.
