Unique Multimeter Readiness Self-Check
The size and location of utility-scale solar sites can present unique challenges whether they’re logistical, environmental, or testing related. Because of that, you want to have confidence that your meter is fully functional, capturing the right data every time so you don’t have to do the same job twice.
The 283 FC features a unique integrated multimeter readiness self-check, that ensures your meter is in proper working order before you take your next reading. This quick self-check is an additional readiness test that gives you valuable insight to the status of your meter’s calibration, battery life availability, test lead functionality, and AC/DC voltage measurement functionality so you can be confident that your meter is ready to work when you are.

Logging/Saving
The 283 FC offers convenient logging and saving features that set it apart from other digital multimeters. With a built-in real-time clock, each measurement can be time- and date-stamped for accurate recordkeeping. The multimeter has internal memory to save and log measurements, which can then be easily transferred to Fluke Connect for further analysis. Additionally, you have the flexibility to customize logging durations and intervals, ensuring the logging process matches the specific needs of the system you are testing.
