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.

▲▲ Warning

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

• Read all safety information before you use the Product.
• Carefully read all instructions.
• Do not alter the Product and use only as specified, or the protection supplied by the Product can be compromised.
• Do not use the Product if it operates incorrectly.
• Do not use the Product if it is altered or damaged.
• Use the Product only as specified, or the protection supplied by the Product can be compromised.
• Limit operation to the specified measurement category, voltage, or amperage ratings.
• Do not touch voltages >30 V ac rms, 42 V ac peak, or 60 V dc.
• Do not exceed the Measurement Category (CAT) rating of the lowest rated individual component of a Product, probe, or accessory.
• Do not use the Product around explosive gas, vapor, or in damp or wet environments.
• Use only correct measurement category (CAT), voltage, and amperage rated probes, test leads, and adapters for the measurement.
• Do not use the HOLD function to measure unknown potentials. When HOLD is turned on, the display does not change when a different potential is measured.
• 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.
• Keep fingers behind the finger guards on the probes.
• Measure a known voltage first to make sure that the Product operates correctly.
• 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 that are not necessary for the measurement.
• Before each use, examine the Product. Look for cracks or missing pieces of the clamp housing or output cable insulation. Also look for loose or weakened components. Carefully examine the insulation around the jaws.
• 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.
• Disconnect power and discharge all high-voltage capacitors before you measure resistance, continuity, capacitance, or a diode junction.
• Hold the Product behind the tactile barrier. See The Product Figure 1 (1).
• Do not use the Product if the wear indicator in the jaw opening is not visible. See The Product Figure 2 (1).
• Do not operate the Product with covers removed or the case open. Hazardous voltage exposure is possible.
• Do not use in CAT III or CAT IV environments without the protective cap 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.

For safe operation and maintenance of the product:

• Remove batteries to prevent battery leakage and damage to the Product if it is not used for an extended period.
• Be sure that the battery polarity is correct to prevent battery leakage.
• Repair the Product before use if the battery leaks.
• Have an approved technician repair the Product.
• Remove the input signals before you clean the Product.

General Specifications

Electromagnetic Compatibility (EMC)

International
IEC 61326-1: Portable Electromagnetic Environment; IEC 61326-2-2, CISPR 11: Group 1, Class A

Group 1: Equipment has intentionally generated and/or uses conductively-coupled radio frequency energy that is necessary for the internal function of the equipment itself.

Class A: Equipment is suitable for use in all establishments other than domestic and those directly connected to a low-voltage power supply network that supplies buildings used for domestic purposes. There may be potential difficulties in ensuring electromagnetic compatibility in other environments due to conducted and radiated disturbances.

Caution: This equipment is not intended for use in residential environments and may not provide adequate protection to radio reception in such environments.

Korea (KCC)
Class A Equipment (Industrial Broadcasting & Communication Equipment)

Class A: Equipment meets requirements for industrial electromagnetic wave equipment and the seller or user should take notice of it. This equipment is intended for use in business environments and not to be used in homes.

USA (FCC)
47 CFR 15 subpart B. This product is considered an exempt device per clause 15.103.

Electrical Specifications

The accuracy specification is defined as ±(% reading + digits) at 23 °C ± 5 °C.

The accuracy specifications apply at 23 °C ±5 °C (73 °F ±41 °F). Below 18 °C and above 28 °C (64 °F and above 82 °F) accuracy degrades at (0.1) times specification per °C. True rms for ac V and ac A accuracy is specified from 5% to 100% of range.

LIMITED WARRANTY

This Fluke product will be free from defects in material and workmanship for 1 years from the date of purchase. This warranty does not cover fuses, disposable batteries, or damage from accident, neglect, misuse, alteration, contamination, or abnormal conditions of operation or handling. Resellers are not authorized to extend any other warranty on Fluke's behalf. To obtain service during the warranty period, contact your nearest Fluke authorized service center to obtain return authorization information, then send the product to that Service Center with a description of the problem.

THIS WARRANTY IS YOUR ONLY REMEDY. NO OTHER WARRANTIES, SUCH AS FITNESS FOR A PARTICULAR PURPOSE, ARE EXPRESSED OR IMPLIED. FLUKE IS NOT LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSSES, ARISING FROM ANY CAUSE OR THEORY. Since some states or countries do not allow the exclusion or limitation of an implied warranty or of incidental or consequential damages, this limitation of liability may not apply to you.

The Product

1 Clamp Meter

A visual representation of the Fluke 317/319 clamp meter is shown. It displays various measurement ranges and settings, including AC/DC current, voltage, resistance, and frequency. Key buttons like ZERO, INRUSH, MIN/MAX, and HOLD are visible. The display shows a numerical reading, and the clamp jaws are depicted with measurement range indicators.

2 Jaw Wear

This section illustrates the importance of checking for wear on the clamp meter's jaws. A diagram shows a close-up of the jaw mechanism, highlighting a wear indicator. The text emphasizes inspecting the jaws for any damage or wear that could affect measurement accuracy.

3 Measurement Setup

This section provides guidance on setting up the clamp meter for measurements. It shows diagrams illustrating how to connect the test leads for different measurement types, such as AC/DC current and voltage. The correct placement of the clamp around a conductor is also depicted, along with the use of the ZERO function.

4 Voltage Measurement

This section details how to measure AC and DC voltage using the clamp meter. Diagrams show the correct connection of the test leads to a voltage source (e.g., a battery and an AC source) and the clamp meter. The display readings for AC and DC voltage are illustrated.

5 Resistance Measurement

This section explains how to measure resistance. A diagram shows the test leads connected to a resistor, and the clamp meter set to the resistance measurement mode. The display shows a resistance reading.

6 Continuity Test

This section describes how to perform a continuity test. Diagrams show the test leads connected to a circuit. When continuity is detected (resistance below a certain threshold, e.g., <30 Ω), the clamp meter emits an audible beep. The display shows the continuity status.

7 Display Hold

This section explains the Display Hold function. A diagram shows the clamp meter with the HOLD button highlighted. When pressed, the current measurement is frozen on the display. The display shows a frozen voltage reading.

8 MIN MAX AVG

This section describes the MIN MAX AVG (Minimum, Maximum, Average) function. Diagrams illustrate how pressing the MIN MAX button cycles through displaying the minimum, maximum, and average values of a measurement. The display shows different readings corresponding to these functions.

9 INRUSH Current

This section explains how to measure inrush current. Diagrams show the clamp meter connected to a motor circuit. The INRUSH button is pressed to capture the initial surge of current when the motor starts. The display shows the inrush current reading (e.g., 8.00 A) and indicates the measurement is AC.
