The main difference between Flukehttps://heiautomation.com/ product models with FC and those without FC lies in whether they support the Fluke Connect function.
Products with FC have the following features:
Wireless connection and data transmission: It can be connected to smartphones, tablets or PCs via wireless methods such as Bluetooth, and with the Fluke Connect mobile app or PC app, real-time monitoring of test results, trend analysis, and automatic data upload to the cloud for remote access and management can be achieved.
Enhanced safety and convenience: Instruments can be remotely controlled from a safe distance in hazardoushttps://www.facebook.com/profile.php?id=100087291657130 environments, such as those with high voltage, high current or arc flash risks. Technicians can place the test tools near the test points and operate and read data through connected mobile devices from a safe distance, reducing safety risks. It also facilitates testing in complex environments without the need for frequent trips between the test points and the reading locations.
Data management and report generation: The PC version of the Flukehttps://heiautomation.com/ Connect app can be used to quickly generate user-defined test reports, which can be sent directly via email on-site or shared in real-time conversations through ShareLive video calls, improving work efficiency and the convenience of data sharing.
Products without FC do not have the wireless connection, remote control, automatic data transmission and convenient report generation functions provided by Fluke Connect. Data needs to be recorded and processed manually, and in some hazardous environments, technicians may need to be closer to the test points for operation and reading.
Here are some common Fluke products that feature “FC”:
FLUKE-1550C FC/CN Insulation Resistance Tester
It can perform up to 5 kV digital insulation tests, capable of measuring various high-voltage equipment, including switchgear, motors, generators and cables; it can cover the entire test voltage range specified in IEEE 43-2000, offers a 3-year warranty, and achieves a CAT IV 600 V safety level. The 1550C / 1550C FC has a measurement memory and a PC interface, which can detect potential faults of the equipment in advance and is an ideal tool for preventive or predictive maintenance plans.

Fluke 370 FC Series Digital Ammeterhttps://heiautomation.com/about/
Including models 374 FC, 375 FC, 376 FC, 377FC, and 378FC, these are of CAT IV 600 V and CAT III 1000 V safety levels. They feature patented rapid measurement technology and proprietary surge measurement technology, which can filter noise and capture motor starting current. Some models are integrated with variable frequency drive low-pass filters, suitable for motor drive measurements.

Fluke 393 FC CAT III 1500 V True RMS Clamp Meter
This clamp meter can measure https://heiautomation.com/voltages up to 1500 V DC and 1000 V AC through the test leads, and can measure currents up to 999.9 A DC or AC through the clamp. The included iFlex flexible current probe can expand the range of AC current measurement to up to 2500 A. This tool is designed for solar photovoltaic (PV) installation technicians and maintenance professionals working in high-voltage direct current environments: PV arrays, wind https://www.youtube.com/@%E6%9B%BE%E6%85%A7%E5%A9%B7-z6jenergy, electrified railways, and UPS uninterruptible power supplies used in data centers. Test results can be recorded, shared, and reported through the Fluke Connect software.

The safety level is CAT III 1500 V/CAT IV 1000 V. It is specially designed for solar professionals and is applicable in fields such as solar photovoltaic arrays, wind energy, electrified railways, and data centers. It can measure up to 1500 V of DC voltage and 60 A of AC/DC current. It can automatically calculate VA power and has an internal real-time clock. Each measurement can add a time and date stamp for convenient data recording and analysis. The FC function can save and record the measurement values in the internal memory and view these measurements on mobile devices via Flukehttps://heiautomation.com/about/ Connect.

Common products without Fhttps://heiautomation.com/contact-us/C, such as Fluke 115 digital multimeter and Fluke 87V industrial multimeter, etc., focus on basic electrical parameter measurement in terms of functionality. They are suitable for some scenarios where the demand for data transmission and remote control functions is not high.
