Fluke 1777

The Fluke 1777 features 20 MHz sampling capability to capture the fastest high-speed voltage transients in exceptional detail. With 500,000 points per capture and bandwidth up to 1 MHz, it provides the resolution needed to identify both impulsive and oscillatory transients that can damage equipment and cause failures.

The 1777 is IEC 61000-4-30 Class A edition 3 compliant and engineered to meet future Class A edition 4 requirements. It conforms to EN 50160 and IEEE 519 standards, providing best-in-class accuracy you expect from Fluke. All measurements use 24-bit synchronous sampling at 80 kS/s for exceptional precision.

Yes, the 1777 measures AC and DC inputs with a voltage range up to 1000 V rms or 1000 V dc (1700 Vpk). It handles DC, 50/60 Hz systems with a wide frequency range from 42.5 Hz to 69 Hz. This makes it suitable for traditional industrial systems, renewable energy installations, and electric vehicle charging infrastructure.

The 1777 measures harmonics up to 30 kHz, including the first 50 integer harmonics plus interharmonics and high-frequency components from 2 kHz to 30 kHz in configurable bins. It complies with IEC 61000-4-7 Class 1 and IEEE 519 for both short-time and very-short-time harmonic analysis, critical for modern inverter-based loads.

The 1777 features a unique automatic measurement capture system that records over 500 power quality parameters by default without requiring threshold setup. Guided setup helps you select the right parameters for your system. This ensures you collect the right data every time, even if you're unsure what to look for initially.

The 1777 supports 4 current inputs for 3-phases and neutral, with automatic range selection based on attached sensors. It handles 1 A to 6000 A with i17XX-FLEX6000 36 inch probes, 40 mA to 40 A with i40s-EL clamps, and 20 A to 2000 A DC with 80i-2010-EL clamps, providing versatility across different applications.

Data downloads are simple using USB memory stick, WiFi, LTE, wired Ethernet, or USB cable. The included Energy Analyze Plus software provides instant data viewing, downloading, and sharing while logging continues. One-touch reporting creates standardized reports conforming to EN 50160, IEEE 519, or GOST 33073 IEC 61000-2-2 standards.

The Fluke 1777 has a best-in-class CAT IV 600 V and CAT III 1000 V overvoltage rating, making it safe for use at service entrances or downstream locations. This rating ensures it can be used confidently in the most demanding measurement environments while maintaining operator safety.
