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 Review: Cool tool - Love it multi purpose tool Review: Excellent inrush current function - I have several more expensive and very capable meters but none of them have a function to measure inrush current. Inrush is the short term current that is present for only a few milliseconds when an electrical load is first turned on. I bought this meter to be able to compare before and after inrush current when installing an air conditioner "soft start" module. It did the trick. It gives repeatable results. The accuracy seems to be good - tested using a calibrated shunt resistor, incandescent light bulb, and oscilloscope. As expected it is designed to capture the inrush typical of a motor's inductive load - it seems to average the first couple of 60Hz power cycles. It will not display the much higher instantaneous peak current that occurs when an incandescent light bulb is turned on just as the power supply waveform is at its peak. This meter is perfect for it's intended use! ## Features - Multifunctional Smart Clamp Meter: The TCM-300A digital clamp meter features both smart and manual measurement modes, allowing for precise measurement of AC current, Capacitance, AC/DC voltage, 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 AC Current Measurement: This amp meter boasts a unique jaw design that allows for quick AC 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-300A 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 | B0D5M81GQJ | | Best Sellers Rank | #184,537 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #118 in Clamp Meters | | Brand | TESMEN | | Brand Name | TESMEN | | Color | Green | | Customer Reviews | 4.6 out of 5 stars 464 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 | Ammeter | | Model | TCM-300A | | Part Number | TCM-300A | | Power Source | Corded Electric, Battery Powered | | Specification Met | RoHS | | Style | AC Current | | Style Name | AC Current | ## Product Details - **Brand:** TESMEN - **Power Source:** Corded Electric, Battery Powered - **Style:** AC Current - **Color:** Green - **Item Weight:** 229.7 Grams ## Images ![TCM-300A Smart Clamp Meter - Image 1](https://m.media-amazon.com/images/I/71Thg8KGY2L.jpg) ![TCM-300A Smart Clamp Meter - Image 2](https://m.media-amazon.com/images/I/71YAzHoBqCL.jpg) ![TCM-300A Smart Clamp Meter - Image 3](https://m.media-amazon.com/images/I/71sH4N47NjL.jpg) ![TCM-300A Smart Clamp Meter - Image 4](https://m.media-amazon.com/images/I/71RqNsfKTYL.jpg) ![TCM-300A Smart Clamp Meter - Image 5](https://m.media-amazon.com/images/I/81kTkRqgsEL.jpg) ## 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.
