Fluke 80E-5 Voltage Divider – 5 kV max.

The Fluke 80E-5 Voltage Divider extends the AC and DC voltage measuring range of compatible multimeters to 5 kV peak. This high-voltage accessory safely divides and measures voltages while minimizing loading effects through precision resistor networks. It is engineered for use with multimeters featuring 10 MΩ input impedance and includes a center zero panel meter for quick assessment of voltage magnitude and polarity.

Technical Specifications

• Maximum Input Voltage: 5 kV peak


• Division Ratios: 500:1 and 5,000:1


• Output Terminals: 10V and 1V outputs


• Resistor Type: Precision wirewound with low temperature coefficient


• Loading Error: Approximately 0.1% when using 10V output with 10 MΩ input impedance multimeters


• Panel Meter: Center zero display for voltage magnitude and polarity observation

Key Features

• Dual output terminals support flexible measurement configurations. The 10V output introduces minimal loading error (≈0.1%) with standard 10 MΩ multimeters, while the 1V output provides extended range capability. Precision wirewound resistors with low temperature coefficients ensure stable, accurate readings across operating conditions. Center zero panel meter provides real-time voltage indication independent of connected test equipment. Case design accommodates both benchtop and rack-mount installation.

Typical Applications

• High-voltage AC and DC measurements requiring safe attenuation


• Field and laboratory voltage measurements up to 5 kV peak


• Systems where standard multimeter input ranges are insufficient

Compatibility & Integration Designed for use with Fluke differential voltmeters and null-type potentiometers. Primary application is with multimeters featuring 10 MΩ input impedance. Fluke differential voltmeters at null present infinite input impedance and eliminate loading error entirely.
