Status: Current Production
Overview
The Fluke 1770 Series is the current flagship three-phase power quality analyzer platform. The 1773, 1775, and 1777 replace the discontinued 430-II Series and 1750 recorders, combining power quality metering and logging in a single handheld instrument. All models are IEC 61000-4-30 Class A Edition 3 compliant, rated CAT IV 600 V / CAT III 1000 V, and measure voltage, current, power, energy, harmonics, dips, swells, and flicker. The 1775 adds 1 MHz transient capture, while the 1777 provides 20 MHz sampling for the fastest transient events up to 8 kV. All models include Fluke Energy Analyze Plus software with automated EN 50160 and IEEE 519 compliance reporting.

Common Fluke 1770 Series Failures We Repair
- Voltage input channel damage from transient overvoltage events beyond safety rating
- Touchscreen digitizer failure from field impact or moisture ingress
- Current probe connector wear from repeated field connections
- Internal memory corruption requiring firmware recovery
- WiFi/BLE module communication failures
- Battery degradation reducing field logging duration
- USB-C port damage from connector stress during data download
Our technicians perform component-level diagnostics on every Fluke 1770 Series unit. We don’t just replace boards — we identify and repair the specific failed components, saving you the cost of full module replacements when possible.
Calibration
Every Fluke 1770 Series repair includes NIST-traceable calibration. We verify all voltage, current, power, and power quality measurement functions against our reference standards and provide a detailed calibration certificate documenting measured performance against the manufacturer’s published specifications.
