Fluke 707 Loop Calibrator Battery 30V

This loop calibrator is a handheld tool for calibration, repair and maintenance of current loops in industrial control and instrumentation environments. It supports sourcing, simulating and measuring mA signals, offers a 24V loop supply with simultaneous current measurement, and provides a fast, one-handed user Interface for loop checks under typical plant conditions.

• 0.015% accuracy delivers precise current measurements and sourcing
• 0.001 mA resolution enables fine adjustment and diagnostics
• Selectable step or ramp outputs supports functional transmitter testing
• 24V loop supply with 250 Ω HART resistor facilitates live loop power and HART devices
• Simultaneous mA and % of span display speeds calibration verification
• Battery powered operation yields 18 h typical runtime for field shifts

• Suitable for commissioning and calibration of 4–20 mA control loops
• Ideal for field maintenance of transmitters and control valves
• Used with PLC analogue outputs to verify voltage and current signals
• Can be used for HART loop checks that require loop power and resistor
• Suitable for troubleshooting process loops in manufacturing plants

It uses alkaline 9V batteries and features a removable battery door for Rapid replacement without tools.

It functions between −10 °C and 55 °C and tolerates relative humidity up to 95% at lower temperatures with reduced ratings at higher temperatures.

It measures 0V dc to 28V dc for loop checks and conforms to a 30V safety category for low-voltage measurement tasks.

The instrument is lightweight at 224 g and supplied in a Compact case with a protective holster for transport and on-site handling.
