Product description
1 AC CURRENT TEST
2 AC/DC VOLTAGE TEST
3 INRUSH CURRENT TEST
4 RESISTANCE TEST
5 NCV TEST
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
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

A very good meter reason to be priced
This is an excellent meter.It’s reasonably priced, and it does a lot

The Trick To Measure AC Current
Works great. When measuring current, the clamp must be around a single wire, not a sheathed cable. If you try to measure current on a sheathed cable containing black, white and ground wires, the currents will cancel and the reading will be zero.

Esta pinza amperimétrica/multímetro me ha sorprendido por su relación calidad-precio, puesto que tiene todas las funciones que brinda uno de primera marca, obteniendo unos resultados de medición idénticos comparando con otro que poseo.Sus principales características son:- Medición de voltaje AC/DC, corriente AC/DC, resistencia, diodos, capacitancia, continuidad, etc…- Cuenta con función de rango automático y manual.- Pantalla LCD retroiluminada de 4 dígitos que se ve perfecta desde cualquier ángulo, con dígitos grandes y una gran resolución.- Escala variable- Indicador de nivel de batería (funciona con 3 pilas AAA incluidas)- Linterna led incorporada (aunque es tenue, para una emergencia puede servir)- Los cables que utiliza son con conexión estándar.- Medición de temperatura- Incluye un cable termopar.- Estuche impermeable con cremallera y asa para mantenerlo protegido y fácil de transportarEn contra, de momento no le he encontrado nada. Me ha parecido muy completo para el uso que yo suelo darles a estos aparatos tanto a nivel doméstico como industrial.Recomendado 100% puesto que además de las funciones que tiene cualquier multímetro, este posee una pinza para medir corriente y voltaje sin contacto, y el precio es de saldo.

La pince est livrée avec des piles, une paire de pointes de touche, une sonde de température, une housse, et une notice en français. C’est un ensemble complet, et c’est un bon point.La qualité de fabrication est bonne. La pince est sécurisée avec une PTC, et elle est protégée pour une classe de risques de catégorie 3 à 600 volts. Elle propose quelques petits plus intéressants, comme l’écran rétro-éclairé, la lampe de poche, ou encore le doublage visuel des alertes sonores.À l’usage, cet appareil se distingue d’un multimètre classique par son mode de fonctionnement. Ici, la part belle est faite à la mesure facile et rapide du courant alternatif jusqu’à 600 ampères. Excusez du peu. Terminé les montages avec insertion en série dans le circuit : on ouvre la pince, on la referme autour du câble de la phase ou du neutre, et c’est fini. Magique, non ?Sinon, la partie multimètre fonctionne plutôt bien. Il suffit de choisir le mode et le bon calibre est sélectionné automatiquement. On a même un mode entièrement automatique, certes un peu plus lent, mais qui parvient à sortir une mesure. L’appareil est réactif, et la précision est très correcte : 6000 points, c’est largement suffisant pour 99,999% des mortels, on n’aura jamais besoin de plus.Presque tous les tests de base sont là : tension alternative (en valeur efficace réelle, ou “True RMS”) et continue, résistance/continuité, capacité, diode, fréquence/rapport cyclique, et même température. Le test NCV va détecter si un câble est sous tension à distance. La fonction “HOLD” est pratique pour garder une mesure à l’écran, et la fonction “MIN”/”MAX” permet de rappeler la plus petite et la plus grande mesure.Au final, je suis très satisfait de cette pince ampèremétrique. Elle est bien construite, suffisamment précise, et le lot est complet. Vendue 10€, le rapport qualité/prix est excellent pour un outil incroyablement pratique.

This is a pretty comprehensive claps meter for a really cheap price and runs off of 3 x AAA batteries. This meter has many features as well as quality of life ones such as a backlit screen and a torch.Testing the clap meter where I fell into the trap of many others thinking it wasn’t working when I tried testing. For those not aware this only work on AC and only on the live or neutral cables which you will find near your electric meter and or fuse board. This does not work with cables that contain both the live and neutral. I really wish these clap would read DC as it would have been great use when working on my car.The multimeter works great and its use case is identical to any other multimeter. The one advantage is this has an auto setting. Personally I’m not a fan of “auto” settings but for those with little experience using such meters or just don’t know what setting to use like my parents this is great for the more casual user.I was surprised to see a this meter comes with a thermocouple to measure temperature. Probably not something that most will use but can be useful for task such and monitoring the flow and return temps on your radiators to help balance your heating system. Or checking the efficiency of the A/C system in your car or house.Overall I think this is a good meter although it feels very prosumer. If you are looking for a clamp meter it might be worth looking for one that does DC as well as AC. If you only want to use the multimeter probes then there are cheaper ones that do just that.

This is a fairly decent digital clamp multimeter as far as clamp multimeters are concerned with the usual functions and typical ranges etc. It appears to be well-built for the most part and works as expected without issues. The backlit screen is fairly easy to read; however, I’m not a big fan of the soft rubber buttons as they are hard to press (or at least not as easy as they otherwise could be with slightly harder plastic material but I digress). It’s fully automatic and auto-ranging although manual selection of specific function is also available (cheaper ones don’t usually offer this). Btw, this is the AC-only model (TCM-300A) for the clamp whereas TCM-300D is AC/DC for the clamp.≡ Physical buildThe physical build quality appears decent although it’s quite typical of most other digital clamp multimeters nowadays. The size is reasonably small (a few others are HUGE which have proven to be rather difficult to use) and it’s generally easy to use overall including the clamp (nothing awkward to press/release the clamp etc. The screen is backlit and easy to read without parallax which is nice.Note that this is (including all other similarly spec’ed copycats) very similar to some of the other well known (and more expensive) brands out there and you can see immediately that this a cheaper version of their more expensive counterparts just based on auto ranging features along but they also cost 4-7x more.≡ FeaturesIn terms features, well, it has all the common and typical units but it also lacks a few that some others (slightly more expensive) have although those advances are nice-to-haves rather than required features in my mind; all the usual features (6-8 of the most common ones) are included which I won’t go into details. Unlike a few others that I’ve come across that only display up to one decimal point (i.e. 0.1V resolution) for DC voltage, this actually displays 3 decimal points (and a relief indeed).≡ TestsI performed a few quick tests both with the clamp and the probes themselves and the results are reasonably accurate in comparison to other known brands. Though, more importantly the results from the clamp match those from the probes for the most part so at least they are consistent. NVC (Non-contact voltage) detection is neat but it’s nothing new and not something to write home about at this point in time. Lastly, it doesn’t appear to have a HOLD feature, I mean, what?≡ ValueAll things considered, this is a fairly decent digital AC clamp multimeter that works as expected for the most part; however, it doesn’t have a hold feature and that’s just shocking to see (not that important but it’s such a common feature). It’s extremely well priced at $10 for what it provides and its build quality, features, usability, and performance. This is almost a steal at this price point.
