With the Fluke 773, you can measure current loops without interrupting them. The major advantage is that the connected components do not need to be taken offline or bypassed for maintenance and verification of the loop. You save time when testing analog inputs and outputs on a PLC. Additionally, this method of measurement prevents the accidental opening of a critical loop, which could lead to operational voltage failures. You can also 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. You can supply mA output signals with a linear ramp or a 25% step output signal, with the 4 to 20 mA output signal automatically adjusted for testing over longer distances. Furthermore, you can measure DC voltages up to 30 V and provide DC voltage of 1 - 5 V or 0 - 10 V. Scaled mA outputs offer a continuous mA signal that corresponds to the 4 to 20 mA signal measured by the mA current clamp. The mA output signal allows a digital logging multimeter or another device to record 4 to 20 mA signals without interrupting the loop. Additionally, an mA input/output is available: simultaneous measurement of the mA signal with the current clamp and provision of an mA signal. Input an mA signal into an instrument and measure 4 to 20 mA at the instrument's output, such as at valves or mA isolators.
