Fluke 715 Volt/mA Loop Calibrator
The Fluke 715 is a calibration tool for process loops, meaning the current and voltage signals often used in instrumentation, control, and troubleshooting. It is used to check, simulate, or adjust signals in a loop to find faults in transmitters, PLC inputs, controllers, and other equipment that works with mA and voltage signals.
It can measure loop current from 0 to 24 mA, allowing it to work with both common 0–20 mA and 4–20 mA signals. At the same time, it can both source and simulate 4–20 mA, making it practical for testing whether the rest of the system responds correctly without needing the actual field transmitter connected. It can also source and measure millivolt and volt signals, making it more broadly applicable than a pure current calibrator.
A useful feature of the Fluke 715 is its ability to provide 24 V loop power while simultaneously measuring current. This means you can quickly check a loop without needing an extra power supply on hand. For a technician, this is particularly relevant because it saves time during troubleshooting and makes it easier to work systematically at the installation site.
Therefore, it is a tool for those who work with process signals in practice and want an instrument that can both measure and simulate the most common signal types in a single unit.
