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.

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
.
•Do not exceed the Measurement Category (CAT) rating of the lowest
rated individual component of a Product, probe, or accessory.
•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.
•Remove all probes, test leads, and accessories that are not necessary
for the measurement.
•Only use probes, test leads, and accessories that have the same
measurement category and voltage rating as the Product.
•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.
•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.
•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. See The
Clamp Meter, item .
•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.
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. The included type-K
thermocouple is rated to 260 °C.

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