Fluke Multi-Function Calibrator, 0.02% Accuracy, 1000V Maximum Voltage Measurement - FLUKE-789


This multi-function calibrator combines the measurement capabilities of a true‑rms digital multimeter with mA loop sourcing and simulation for field and workshop use. It is designed for technicians working on current loop control and electrical measurements, offering battery operation, HART connectivity and rugged safety ratings suited to demanding industrial environments.

Features & Benefits


• 0.02%+2 accuracy for precise calibration tasks
• 1000V true‑rms measurement enabling high‑voltage diagnostics
• 30mA measurement range with 1mA resolution for loop checks
• AA battery power delivering 140h measurement runtime
• CAT IV600V/CAT III1000V safety rating for industrial locations
• HART port support with 24V loop power for transmitter maintenance

**Applications**


• Suitable for commissioning and calibrating 4–20mA control loops
• Ideal for on-site HART transmitter configuration and testing
• Used for voltage and current diagnostics in automation panels
• Can be used for periodic calibration of loop-powered sensors
• Used with field controllers during process instrumentation troubleshooting

What input power options are provided for sourcing currents?


It can source up to 20.000mA from internal AA batteries and simulate up to 20.000mA using an external 15–48V loop supply, both able to overrange to 24.000mA.

How does the device cope with varied ambient temperatures?


Operational limits span -20°C to 55°C with a specified temperature coefficient of 0.05xaccuracy per °C outside 18–28°C.

What protection and approvals support use in industrial sites?


The instrument meets IEC61010‑1 safety standards and is rated CAT IV600V/CAT III1000V with Pollution Degree2 specifications.

What measurement modes and display behaviours aid troubleshooting?


It provides simultaneous mA and percentage‑of‑scale readouts, min/max/average/hold/relative modes, and true‑rms AC measurement to 1000V.

What output drive and compliance are available for loop supplies?


Internal output offers 24V compliance or 1200Ω drive at 20mA, while the 24V loop supply delivers greater than 24V into 250Ω at 20mA.

Supplied with

AC175 alligator clips, AA 1.5 V alkaline batteries (x4, installed), TL71 safety-designed test lead set
