A two-prong cable has live and neutral wires; a three-prong adds ground. Current flows oppositely in live and neutral wires, canceling magnetic fields. Clamping both may show zero. For accuracy, clamp each wire separately Why is it necessary to clamp a single conductor with a clamp meter to measure current instead of the entire power cable? A two-prong cable has live and neutral wires; a three-prong adds ground. Current flows oppositely in live and neutral wires, canceling magnetic fields. Clamping both may show zero. For accuracy, clamp each wire separately Where is the NCV function implemented on the clamp meter? The NCV probe of the clamp meter is located at the protruding part of the clamp tip. Simply bring the clamp meter tip close to the object being detected when using the NCV function Where is the NCV function implemented on the clamp meter? The NCV probe of the clamp meter is located at the protruding part of the clamp tip. Simply bring the clamp meter tip close to the object being detected when using the NCV function How long does the data hold function last? The data hold function will last until you press "H" again to exit the data hold mode How long does the data hold function last? The data hold function will last until you press "H" again to exit the data hold mode Which hole do the red and black test leads insert into? The red test lead connects to the INPUT jack, and the black test lead connects to the COM jack Which hole do the red and black test leads insert into? The red test lead connects to the INPUT jack, and the black test lead connects to the COM jack ## Features - Versatile AC/DC Clamp Meter: The TCM-300D digital clamp meter features both smart and manual measurement modes, allowing for precise measurement of AC/DC current&voltage, Capacitance, NCV(non-contact voltage testing), Inrush, Live, Resistance, Diodes, Continuity, Frequency, and Temperature. Easy to use in both industrial and home settings, this clamp meter is an essential tool for various electrical tasks - Large Jaw Design: This amp meter boasts a unique large design that allows for quick AC/DC current measurements without touching or interrupting the circuit. Simply open the jaw, encircle the conductor, and ensure it is centered for easy operation. NOTE: When using a clamp meter to measure current, make sure to clamp around a single live wire, not the entire power cable - Inrush Current Measurement: This clamp multimeter includes advanced inrush current measurement capabilities, enabling quick identification of startup issues related to motors or starting circuits. It can measure inrush currents ranging from 5 to 600 A, applicable only in AC current mode, allowing users to troubleshoot effectively - Safety First, Complete Package: Certified to CAT III 600V and RoHS standards, this clamp meter is equipped with overload protection and features both audible and visual alarms. The package includes the digital clamp meter, two test leads, a pair of temperature probe pens, a carrying case, three AAA batteries, and a user manual, providing everything you need for a complete measuring experience - User-Friendly: The TCM-300D digital clamp meter features a large, high-definition color display, ensuring easy data reading in any environment. It also includes data hold, auto shut-off, low battery indication,flashlight, and backlit display. Suitable for a wide range of applications, it meets the needs of both professionals and hobbyists, making measurements more convenient, efficient, and easy to use ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D5M5LZBP | | Best Sellers Rank | #129,531 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #81 in Clamp Meters | | Brand | TESMEN | | Brand Name | TESMEN | | Color | Green | | Customer Reviews | 4.6 out of 5 stars 574 Reviews | | Included Components | clamp meter,test leads,temperature probe pens,bag,batteries,user manual | | Item Dimensions | 7.68 x 1.81 x 0.98 inches | | Item Weight | 229.7 Grams | | Item dimensions L x W x H | 7.68 x 1.81 x 0.98 inches | | Manufacturer | TESMEN | | Measurement Type | Multimeter | | Model | TCM-300D | | Part Number | TCM-300D | | Power Source | Battery Powered | | Specification Met | Cat Iii 600v, Rohs | | Style | AC/DC Current | | Style Name | AC/DC Current | ## Product Details - **Brand:** TESMEN - **Color:** Green - **Item Weight:** 229.7 Grams - **Power Source:** Battery Powered - **Style:** AC/DC Current ## Images ![TCM-300D Smart Clamp Meter - Image 1](https://m.media-amazon.com/images/I/71Lk9S+ge7L.jpg) ![TCM-300D Smart Clamp Meter - Image 2](https://m.media-amazon.com/images/I/71RLaVeqW-L.jpg) ![TCM-300D Smart Clamp Meter - Image 3](https://m.media-amazon.com/images/I/715QwONIF1L.jpg) ![TCM-300D Smart Clamp Meter - Image 4](https://m.media-amazon.com/images/I/7108IgjSNYL.jpg) ![TCM-300D Smart Clamp Meter - Image 5](https://m.media-amazon.com/images/I/71+sgdLfkqL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Why is it necessary to clamp a single conductor with a clamp meter to measure current instead of the entire power cable?** A: A two-prong cable has live and neutral wires; a three-prong adds ground.
