The CL310 documenting multi-function calibrator delivers a feature set unmatched in high accuracy, hand-held calibrators in its price range. The CL310 delivers functions and accuracy associated with fixed installation, laboratory instruments, and has everything needed for virtually any calibration task. What makes this versatile calibrator best in class is the ability to fully document any calibration easily while performing the normal job. Software is included. Some functions will require a Microsoft Excel-compatibility.
CL310 can also measure and source thermocouples, RTDs, current, voltage, frequency, and it can source pulse trains. Arrow keys, direct numeric keypad entry, and three softwaredriven function buttons combine with a large, backlit, menu-driven graphics display to provide a highly intuitive yet powerful interface. A built-in 250 Ù resistor for Hart® compatibility; compatibility with smart transmitters and PLCs, full fuseless protection, and a serial communications port for control using ASCII commands are additional features that make the CL310 indispensable for calibration tasks. This product is battery operated.
