Our Testing Experience

First Impressions

When I first unboxed the Fluke 787B ProcessMeter, I was surprised by its compact size—measuring just about 3.35 x 6.3 x 11.6 inches, it felt solid but easy to hold. Right away, I wanted to try out the 20 mA DC current source feature. Setting it up was straightforward, and the screen was clear and easy to read. It felt professional, like a tool made for serious work.

Daily Use

Over the next few days, I used the ProcessMeter in different environments. It was great to have a loop calibrator and DMM all in one. I tested loops and measured voltages up to 1000 volts safely, thanks to its IEC 1010 CAT III rating. The true-RMS readings were accurate and stable, which made my job easier. I appreciated how the buttons responded well, even when I was wearing gloves on a chilly morning.

Key Features in Action

The 20 mA current source was a game changer for me. It let me simulate current loops without needing extra equipment. The precision true-RMS digital multimeter was very useful, especially when working with tricky signals that other meters might misread. The safety rating gave me confidence when testing high voltages, and the compact size meant it fit easily in my tool bag without adding bulk.

Long-Term Performance

After using the Fluke 787B for several weeks on various projects, it still performs just as well as on day one. The battery life is solid, and the readings remain reliable. I haven’t had any issues with the buttons or display, even after some rough handling on site. Overall, it feels like a durable tool that will last a long time and keep delivering accurate results every day.
