These reviews really highlight the value of the product. For temperature readings, it’s best to use a dedicated sensor or a reliable thermometer instead. I’ll opt for a dedicated sensor or a temperature gun, but I won’t use it until I develop some cooling solutions or start working with reflow processes. Right now, I don’t see much need for those unless I build something involving subzero temperatures or BGA work. I’m not planning to rely on reflow beyond that since my current setup uses a GTS 250. Multimeters aren’t worth the cost here; I’ll stick with a basic one later when I have more funds. My focus is on voltmetering, troubleshooting PC components, and experimenting with power supplies for future projects.
NCV doesn't measure contact voltage directly. Simply place the meter's sensor near a wire—such as inside a wall—and it will sense any AC current flowing through it. UT33D+ is a 2000-count multimeter, offering fewer decimal places as voltage rises compared to higher-count models like 6000 or 10000. It provides three decimal digits up to about 2 volts, then two digits up to 20 volts, and only one digit above 20 volts. With a 6000 or 10000-count meter, you receive more precision. UT33D+ supports AC current measurement, whereas UT33D+ cannot. It offers better accuracy for AC voltages (1.2% versus 0.8%) and includes capacitance and hFe measurements, though those features aren't essential in this context. It also features frequency measurement, which can be handy in specific situations (e.g., checking oscillator or crystal frequencies to verify chipset operation), though its usefulness varies. The REL function helps eliminate the meter's own resistance when testing tiny resistors—simply short the leads, press REL to zero, and measure small components. MIN/MAX settings are mentioned, but it's unclear if UT33D+ displays true RMS values. As noted, this matters mainly when measuring AC signals that aren't perfectly sinusoidal, such as those from inexpensive inverters or simulated sine waves. If you lack funds or prefer a more affordable option, UT33D+ is a solid choice—it's significantly better than budget meters under $6 or $830, which often lack precision and advanced features.
It’s not necessary to be super exact with voltages because they’re already close to the limits for CPUs and GPUs. Pushing higher voltages won’t require precise numbers, especially if you’re using them in larger amounts. For troubleshooting a chipset, checking the crystal seems more practical than trying fixes that don’t work. Resistors usually have their resistance clearly marked, and math can help estimate values if needed. The min-max function is useful for analyzing ranges, but you won’t be dealing with AC mains voltage until you start building circuits. At around $9, most options seem to cover what you need, and swapping it would be easy.
