DescriptionFluke 773 Milliamp Process Clamp MeterThe Fluke 773 Milliamp Process Clamp Meter is designed to help process technicians troubleshoot and maintain 4–20 mA control loops quickly and efficiently. By measuring milliamp signals without breaking the loop, it allows users to diagnose problems without shutting down the system, helping prevent costly downtime and missed faults during live processes.Highly portable and versatile, the meter can measure up to 99.0 mA non-contact, making it ideal for troubleshooting transmitters, valves, and programmable logic controllers (PLCs) in industrial environments. The detachable clamp section can be used as a remote jaw with an extension cable, making it easier to take measurements in tight panels or hard-to-reach areas. With the ability to source and measure DC voltage, the meter is also suitable for testing voltage input and output devices that use 1–5 V or 0–10 V signals.Designed for demanding fieldwork, the meter includes a built-in measurement spotlight for improved visibility in dark enclosures, along with a dual backlit display that shows both mA measurements and the percentage of the 4–20 mA span simultaneously. Additional features such as Hold function, automatic power-off, and advanced loop troubleshooting capabilities make it a practical and reliable tool for industrial maintenance professionals.Key FeaturesMeasure 4–20 mA signals without breaking the loop, reducing downtime during troubleshootingMeasure up to 99.0 mA non-contact for fast diagnosticsIdeal for testing transmitters, valves, and PLC systems in process plantsDetachable clamp with extension cable for measurements in tight spacesMeasure and source DC voltage signals (1–5 V and 0–10 V devices)Integrated measurement spotlight for improved visibility in dark panelsDual backlit display showing mA measurement and % of 4–20 mA span simultaneouslySimultaneous mA in-circuit measurement with 24 V loop power for transmitter testingLinear ramp and 25% step output for mA or voltage signalsHold function to capture readings for recording and verificationAutomatic power-off to help extend battery lifeWhat’s IncludedFluke 773 Milliamp Process Clamp MeterTL75 test leads (1 pair)AC72 detachable clipTL940 mini hook test leads (1 pair)4 × AA alkaline batteries (installed)Magnetic hanging strapSoft carrying caseQuick reference guide3-year warranty
