Multimeters

You have a FNIRSI multimeter that locks up for over two minutes, and it leaves you feeling helpless. This is a frustrating issue that can stop your work cold. Many users discover this freeze happens because of the meter’s automatic range selection and internal capacitor discharge cycles. It is a safety feature, not a defect. … Read more

You have probably noticed your newer FNIRSI multimeter no longer has separate buttons for voltage, resistance, and current. This change is more than just a design choice; it affects how quickly you can switch between measurements during a project. Modern FNIRSI interfaces use a single rotary dial and a smart auto-sensing system to detect what … Read more

You plug in a large capacitor and the auto ranging on your FNIRSI multimeter feels like it is stuck in slow motion. This is a common frustration that makes you wonder if your meter is broken. The delay happens because the meter’s internal circuitry needs extra time to charge the capacitor during the test. A … Read more

If you just unboxed your FNIRSI multimeter and wondered why there are no built-in alligator clips, you are not alone. This missing feature matters because alligator clips make it much easier to test wires or components without holding the probes steady with both hands. FNIRSI designs their multimeters for hobbyists and technicians who need precise … Read more

You might wonder why your FNIRSI multimeter won’t charge with just any USB-C PD charger. This matters because using the wrong charger could damage your meter or not work at all. The issue is that the FNIRSI multimeter expects a specific voltage and data handshake, not the variable power that PD chargers deliver. Many PD … Read more

You might have noticed your FNIRSI multimeter only measures AC voltage accurately up to around 450 Hz. This matters because standard household electronics and many audio circuits run at frequencies far above that point. This frequency limit is a common design choice for budget-friendly meters, not a defect. They prioritize stable DC readings and lower … Read more

Why don’t captured values persist next to the graph on my FNIRSI Multimeter after power? This is a common frustration when your multimeter screen goes blank and you lose those important readings. It matters because you rely on those captured values to troubleshoot circuits or compare measurements over time. The FNIRSI multimeter uses volatile memory … Read more

When I first opened my FNIRSI multimeter, I was confused seeing only one input channel. It matters because most multimeters have multiple jacks for measuring voltage, current, and resistance. This single-channel design is actually a clever safety feature. It forces you to use the correct probe setup for each measurement, which helps prevent dangerous mistakes … Read more

FNIRSI LC1020E vs FNIRSI LCR-ST2: Best LCR Meter for Precision Component Testing? I’ve spent time with both the FNIRSI LC1020E 100kHz LCR Meter and the FNIRSI LCR-ST2 100kHz LCR ESR Meter Tweezer, and the choice really comes down to how you work. The LC1020E is a benchtop-style unit with a 19,999-count display and a 2.8″ … Read more

You want to change the sampling rate on your FNIRSI multimeter, but the option simply isn’t there. This is frustrating when you are trying to capture a fast-changing signal or a brief voltage spike. The core reason is that FNIRSI locks the sampling rate to keep the measurement stable and the price low. A fixed … Read more
