You bought an FNIRSI multimeter and now that constant beep is driving you crazy. You just want silence, but the button to turn it off seems to do nothing. This matters because a noisy meter can be frustrating and distracting during precise work. The beep is actually a safety feature designed to warn you about … Read more

You can manually turn off the signal generator on your FNIRSI directly from its screen using the output button. This simple step saves your battery and protects your connected circuits from unwanted signals. On most FNIRSI models, the same button that turns the generator on also turns it off with a quick press. I find … Read more

You are wondering if your FNIRSI multimeter can handle high energy circuits. This is a critical safety question that every DIYer and technician must answer before testing power supplies or industrial equipment. High energy circuits often involve dangerous voltage spikes and massive current surges. Even a budget-friendly FNIRSI meter has specific limits written in its … Read more

Using a FNIRSI multimeter means dealing with those sharp probe tips that can easily poke or scratch you. It matters because a painful jab can make you flinch and cause a dangerous mistake with live circuits. The probes are sharp by design to pierce through wire insulation for accurate readings, but that same point can … Read more

There is nothing more frustrating than opening a brand new FNIRSI multimeter only to find a broken test lead. This common issue matters because faulty leads can ruin your first impression and delay your projects. The problem often lies in the thin plastic used near the probe tips, which can crack during shipping. Many users … Read more

Your FNIRSI multimeter’s auto range feature sometimes picks the wrong measurement. This can be frustrating when you are testing circuits and getting confusing readings. The issue usually happens when the meter tries to guess the best range for a fluctuating or unknown signal. It can also be caused by dirty probes or a weak battery. … Read more

Many FNIRSI multimeters come from the factory with the on-screen menus set to Chinese. If you cannot read the characters, navigating the settings can feel impossible. Knowing how to switch the language is the first step to using all your meter’s features. The language setting is often hidden deep inside the system menu, not in … Read more

You bought an FNIRSI multimeter and noticed it feels lighter and less solid than a Fluke. This matters because build quality affects how long your meter lasts and how safe it is to use. The truth is Fluke meters are built for industrial use with thick rubber armor and high-grade components. FNIRSI targets hobbyists and … Read more

I have asked myself the same question many times. You want both irons plugged in and ready to go, but the FNIRSI station simply will not let you. This matters because it affects how you work, especially when switching tips or needing a second iron for a different job. The station is designed with a … Read more

Your FNIRSI multimeter might not detect logic-level MOSFETs the same way it detects standard ones. This can be frustrating when you are trying to test a component for a project. Logic-level MOSFETs require a very low gate voltage to turn on, often just 2.5V or 3.3V. Your multimeter’s diode test mode might not provide enough … Read more
