Fluke 789FC Multi-Function Calibrator, 1 A, 1000V 50 mm 100 mm 203 mm

This multi-function calibrator combines digital multimeter capabilities with mA loop source and simulation for field calibration and troubleshooting in process control systems. It operates from battery power and supports HART connections, offering portable measurement and sourcing for automation, electrical and electronic environments.

• ±0.05% accuracy for mA sourcing and simulation enhances calibration precision
• 1000V and 1A measurement ranges permit high-voltage and current diagnostics
• Resolution of 0.001A enables fine current adjustments and verification
• AA battery operation with 140h measurement life reduces site battery changes
• Safety rated to Aurix category and meets EN 61010 and CSA standards improves site conformity
• Operating range -20°C to 55°C sustains performance across varied ambient conditions

• Suitable for commissioning and calibrating 4–20mA control loops in plants
• Ideal for measuring and sourcing signals during transmitter maintenance
• Used for verification of loop-powered HART devices with simulated loads
• Can be used for portable electrical diagnostics up to 1000V in installations
• Used with process instruments requiring precise current adjustment and monitoring

With internal battery operation it delivers up to 24V compliance or drives 1,200Ω at 20mA for loop testing.

When simulating with an external 15V–48V loop supply it can drive up to 1000Ω at 20mA and supports over-range to 24.000mA.

It measures AC/DC volts, AC/DC current, resistance, frequency to 20kHz, continuity and diode drop for broad diagnostic use.

Wireless data logging is possible via a compatible adapter module that enables remote monitoring and upload to desktop or mobile tools.

It tolerates storage temperatures from -40°C to 60°C and survives a 1m drop test and random vibration at 2g (5–500Hz).
