123B/124B/125B Calibration Manual Safety Information A Warning identifies hazardous 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. XW Warning To prevent possible electrical shock, fire, or personal injury: • Read all safety information before you use the Product. • Use the Product only as specified, or the protection supplied by the Product can be compromised. • Carefully read all instructions. • Do not apply more than one phase of a multiphase system simultaneously to any COM ˜ (Common) connection. All Common (COM) connections should be equipotential, as marked. • Remove the batteries if the Product is not used for an extended period of time, or if stored in temperatures above 50 °C. If the batteries are not removed, battery leakage can damage the Product. • The battery door must be closed and locked before you operate the Product. • 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. • 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. • Use Product-approved measurement category (CAT), voltage, and amperage rated accessories (probes, test leads, and adapters) for all measurements. • Measure a known voltage first to make sure that the Product operates correctly. • Use the correct terminals, function, and range for measurements. • De-energize the circuit or wear personal protective equipment in compliance with local requirements before you apply or remove the flexible current probe from hazardous live conductors. • Do not touch voltages >30 V ac rms, 42 V ac peak, or 60 V dc. • Do not use the Product around explosive gas, vapor, or in damp or wet environments. • Do not use the Product if it operates incorrectly. • 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 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. • Use only cables with correct voltage ratings. • Connect the common test lead before the live test lead and remove the live test lead before the common test lead. • Keep fingers behind the finger guards on the probes. • Remove all probes, test leads, and accessories before the battery door is opened. • Remove all probes, test leads, and accessories that are not necessary for the measurement. 2
