Introduction

The Fluke 323/324 PLUS Clamp Meter (the Product) measures ac and dc voltage, ac current,

resistance, and continuity. The 324 PLUS can also measure capacitance, contact

temperature, and dc current. Note that the 324 PLUS is shown in all of the illustrations. For

temperature measurement, you must use the included K-Type Thermocouple.

XWWarning

Safety Information

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.

•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 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.

323/324 PLUS

Users Manual

•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.

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 the Product if it is damaged.

•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

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.

323/324 PLUS

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.

•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.

•Do not use in CAT III or CAT IV environments without the protective cap

(if included with the Product) installed on test probe. The protective cap

decreases the exposed probe metal to <4 mm. This decreases the

possibility of arc flash from short circuits.

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.
