Safety Information

A Warning identifies conditions and procedures that are dangerous to the user. A Caution identifies conditions and procedures that could cause damage to the Product or the equipment under test.
International electrical symbols used on the Product and in this manual are explained in Table 1.

• CAT II MEASUREMENT CATEGORY II is applicable to test and measuring circuits connected directly to utilization points (socket outlets and similar points) of the low voltage MAINS installation.
• CAT IV MEASUREMENT CATEGORY IV is applicable to test and measuring circuits connected at the source of the building’s low voltage MAINS installation.
• CAT III MEASUREMENT CATEGORY III is applicable to test and measuring circuits connected to the distribution part of the building’s low-voltage MAINS installation.

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

• Carefully read all instructions.
• Use the Product only as specified, or the protection supplied by the Product can be compromised.
• Use only correct measurement category (CAT), voltage, and amperage rated probes, test leads, and adapters for the measurement.
• Do not touch voltages > 30 V ac rms, 42 V ac peak, or 60 V dc.
• Hold the Product behind the tactile barrier. See The Clamp Meter item ①.
• Do not use test leads if they are damaged. Examine the test leads for damaged insulation or exposed metal. Check test lead continuity.
• Do not measure current while the test leads are in the input jacks.
• Do not use the Product around explosive gas, vapor, or in damp or wet environments.
• Limit operation to the specified measurement category, voltage, or amperage ratings.
• Do not work alone.
• Do not apply more than the rated voltage, between the terminals or between each terminal and earth ground.
• Comply with local and national safety codes. Use personal protective equipment (approved rubber gloves, face protection, and flame-resistant clothes) to prevent shock and arc blast injury where hazardous live conductors are exposed.
• Replace the batteries when the low battery indicator shows to prevent incorrect measurements.
• The battery door must be closed and locked before you operate the Product.
• Measure a known voltage first to make sure that the Product operates correctly.
• Use only probes, test leads, and adapters supplied with the Product.
• Remove all probes, test leads, and accessories that are not necessary for the measurement.
• Keep fingers behind the finger guards on the probes.
• Connect the common test lead before the live test lead and remove the live test lead before the common test lead.
• Do not use the Product if it is damaged.
• Do not use the Product if it operates incorrectly.
• Before each use, examine the Product. Look for cracks or missing pieces of the clamp housing. Also look for loose or weakened components. Carefully examine the insulation around the Jaws.
• Examine the case before you use the Product. Look for cracks or missing plastic. Carefully look at the insulation around the terminals.
• Read all safety Information before you use the Product.
• Remove batteries to prevent battery leakage and damage to the Product if it is not used for an extended period.
• Remove batteries to prevent battery leakage and damage to the Product if is to be stored above its operating temperature.
• Do not use a current measurement as an indication that a circuit is safe to touch. A voltage measurement is necessary to know if a circuit is hazardous.

Note
The Measurement Category (CAT) and voltage rating of combinations of test probes, test probe accessories, current clamp accessories, and the Product is the LOWEST rating of individual components.

How to Clean the Product
Regularly wipe the case with a damp cloth and mild detergent.
Caution To prevent damage to the Product, do not use abrasives or solvents to clean the Product case.
