Our Testing Experience

First Impressions

When I first unboxed the Fluke 787B ProcessMeter, I was impressed by its solid build and surprisingly compact size—just about 3.35 by 6.3 by 11.6 inches. Right away, I noticed it felt sturdy and well-made in my hands. I started testing its 20 mA DC current source and loop calibrator features, and it was easy to get going without digging through complicated manuals. The clear display and intuitive buttons made the first tests smooth and straightforward.

Daily Use

Using the 787B every day on my projects quickly showed how handy it really is. Whether I was measuring voltage or current, or simulating loops, it handled tasks without any fuss. Its true-RMS digital multimeter feature gave me accurate readings even when working with tricky signals. I liked that it meets the 1000 volt IEC 1010 CAT III safety standard, so I felt confident using it around high voltage equipment. It became my go-to tool for daily electrical testing.

Key Features in Action

The standout feature for me was the 20 mA DC current source combined with the loop calibrator and simulator functions. These made calibrating process instruments much faster and more reliable. The true-RMS measurement was another big plus—getting precise readings on complex waveforms saved me time troubleshooting. Plus, the high voltage rating gave me peace of mind. The compact size meant I could easily carry it around without feeling weighed down.

Long-Term Performance

After using the Fluke 787B for several weeks, I can say it held up well. The battery life stayed strong, and the accuracy remained consistent. It didn’t show any signs of wear despite regular use in different environments. The device’s rugged design really stood out, proving it’s built to last. Overall, it’s been a reliable partner on my electrical testing jobs, and I’d trust it again for future work.
