Fluke Multimeter, ±0.3% DC Voltage Accuracy, 400h Battery Life - FLUKE-77-4/EUR

This multimeter is a handheld digital instrument designed for diagnosing electrical and electronic systems in field service and bench repair environments. It performs AC and DC measurements, frequency and capacitance checks, Plus resistance and continuity testing, and is intended for professionals in automation, electronics, electrical and mechanical industries.

Features & Benefits

• 1000V maximum terminal-to-earth measurement protects equipment and user
• DC voltage accuracy of ±0.3% delivers precise low-voltage readings
• AC current accuracy of ±2.5% supports reliable alternating-current diagnostics
• 400h alkaline battery life reduces downtime between battery changes
• 33-segment bargraph provides quick Visual trend assessment
• 20A overload capability for short-duration current testing

Applications

• Suitable for fault finding on industrial control panels and drives
• Ideal for calibration checks on sensors and transducers
• Used for verifying motor and pump electrical loads during maintenance
• Can be used for PCB-level troubleshooting in electronics workshops
• Suitable for testing building electrical installations up to 1000V

What display capabilities help when monitoring fluctuating signals?

The display offers 6,000 counts with a fast-update bargraph that refreshes at 32/sec to show Rapid changes clearly.

How does the instrument handle surge events during testing?

It includes 8kV Peak surge protection per IEC 61010 for enhanced survivability against transient impulses.

What measurement ranges are available for capacitance and frequency?

Capacitance is measured up to 9,999 μF with varying resolution, and frequency is specified up to 99.99 kHz for AC voltage inputs.

What input protection is fitted for current measurements?

Fast fuses are provided: a 440 mA fuse for small-current inputs and an 11 A fast fuse for higher-current inputs.

How does the meter perform under different environmental conditions?

It operates between −10°C and +50°C, stores between −40°C and +60°C, and is specified for use up to 2,000m altitude.

Note

For Calibrated Articles - Accuracy is specified for 1 year after calibration, at operating temperatures of 18 °C to 28 °C, with relative humidity at 0 % to 90 %
