As current flows through it, a proportional voltage drop (75mV at full scale) is generated across its terminals. Your ammeter or data-acquisition system reads this millivolt signal and converts it to a current display. This approach protects your measuring instrument and allows safe monitoring of very high currents.\u003c\/p\u003e\n\n\u003cp\u003eFor guidance on electrical measurement safety and best practices, refer to the \u003ca href=\"https:\/\/www.osha.gov\/electrical\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eOSHA Electrical Safety guidelines\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: What ammeter or meter is compatible with this FL-2 DC shunt?\u003c\/h4\u003e\n\u003cp\u003eA: Any DC panel ammeter, digital meter, or data logger that accepts a standard 75mV full-scale input signal is compatible with this FL-2 shunt. This is the most common signal standard for DC current shunts worldwide.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I select the correct current rating for my application?\u003c\/h4\u003e\n\u003cp\u003eA: Choose a shunt rated at or just above your circuit's maximum continuous current. For example, if your solar array produces up to 180A, select the 200A rated shunt. Operating the shunt at or below its rated current ensures accuracy and prevents overheating.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this shunt be used in solar PV or battery storage systems?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The FL-2 shunt is widely used in off-grid and on-grid solar systems, lithium or lead-acid battery banks, and EV charging setups. Its bolt-on terminals allow easy integration into bus-bar assemblies common in these installations.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the 0.5% accuracy maintained across all current ratings?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. All current ratings in the FL-2 series are manufactured to Accuracy Class 0.5%, meaning the measurement error is within ±0.5% of the full-scale value under rated conditions.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What ammeter or meter is compatible with this FL-2 DC shunt?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Any DC panel ammeter, digital meter, or data logger that accepts a standard 75mV full-scale input signal is compatible with this FL-2 shunt.
