Fluke 287 CAL True-RMS Electronics Logging Multimeter with TrendCapture

The Fluke 287 CAL is a True-RMS digital multimeter engineered for electronics troubleshooting, maintenance, and design verification in field and lab environments. It combines high-precision DC/AC voltage and current measurements with integrated data logging and graphical trend analysis. The CAL designation confirms factory calibration and documented accuracy upon delivery. TrendCapture technology instantly visualizes logged data to expose anomalies and performance drift without requiring PC downloads or post-analysis.

## Technical Specifications

**Voltage & Current Measurements**
• DC Voltage: 0–1000 V, 0.025% basic accuracy

**Logging & Trend Analysis**
TrendCapture graphically displays logged data in real time. The multimeter stores up to 15,000 recorded events across 180 hours of logging memory. Auto-hold thresholds trigger new events based on specified percentage changes in readings. 14x digital zoom enables detailed inspection of trend data. Multiple logging sessions operate independently without requiring data downloads to a PC.

**Display & Interface**
1/4 VGA display with 50,000 counts resolution and white backlight. Simultaneous measurement display supports multiple data streams on-screen. Peak capture records transients as fast as 250 μs. Selectable AC filtering reduces noise on rapidly changing signals. Field measurements can be named and recalled. Multi-lingual interface supported.
