Introduction The Fluke 323/324/325 Clamp Meters (the Product) measure ac and dc voltage, ac current, resistance, and continuity. The 324 and 325 can also measure capacitance and contact temperature. The 325 can also measure dc current and frequency. Note that the 325 is shown in all of the illustrations. For temperature measurement, you must use the included K-Type Thermocouple. XWWarning Read "Safety Information" before you use the Product.

Clamp Meter Safety Information To prevent possible electrical shock, fire, or personal injury: • 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. • Carefully read all instructions. • Hold the Product behind the tactile barrier. See The Clamp Meter, item .
323/324/325 Users Manual 4 • Comply with local and national safety codes. Use personal protective equipment (approved rubber gloves, face protection, and flameresistant 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.
Clamp Meter Safety Information • Connect the common test lead before the live test lead and remove the live test lead before the common test lead. • Remove all probes, test leads, and accessories before the battery door is opened. • Do not use and disable the Product if it is damaged. • Do not use the Product if it operates incorrectly. • Do not use test leads if they are damaged. Examine the test leads for damaged insulation, exposed metal. Check test lead continuity.
323/324/325 Users Manual • 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. WCaution To avoid possible damage to the Product or to equipment under test, use a thermocouple rated for the temperatures to be measured. The Product is rated for -10.0 °C to +400.0 °C and 14 °F to 752 °F.
