With the Fluke 772, you can measure current loops without interrupting them. The major advantage is that maintenance and verification of the loop can be performed without taking the connected components offline or having to bypass the loop in a complicated manner. You save time when testing analog inputs and outputs on a PLC. Furthermore, this type of measurement can prevent the accidental opening of a critical loop, which could lead to operational voltage failures. Additionally, you can measure current loops directly on the device using serial measurement sockets, provide and simulate signals between 4 and 20 mA, and measure current loops while simultaneously powering the loop with 24 V. It is possible to output mA signals with a linear ramp or a 25% step output signal (automatic adjustment of the 4 to 20 mA output signal for tests over longer distances).
