Extech 412355A Current and Voltage Calibrator/Meter

The 412355A is built to serve as both a precision source and a meter in one compact unit. In source mode, it delivers adjustable output currents from 0 to 24 mA and voltages up to 10–20 V (depending on the model configuration). In measure mode, it can read currents up to 50 mA and voltages within its calibrated ranges. Its flip-up (oyster-style) display allows for clear readings in either bench or field setups, while the touch keypad provides intuitive control over functions and output settings. This calibrator supports storing up to five custom calibration presets, enabling quick setup for recurring tasks. The display can show readings in several formats—milliamps, percent of full scale, or millivolts—depending on the calibration mode. It includes a large LCD, sturdy housing, and is supplied with accessories including a 9 V battery, calibration cable with spade lug terminals, carrying case, neck strap, and an AC adapter. Because the device is versatile and self-contained, technicians can carry fewer separate tools for calibration, measurement, and verification work in process control environments.     Features Sources current from 0 to 24 mA Sources voltage output in a calibrated range (e.g. up to 10–20 V) Measures DC current up to 50 mA Flip-up “oyster” display for flexible viewing angles Touch keypad for easy configuration Stores five user calibration presets Display modes: mA, percent, mV Supplied with battery, calibration cable, AC adapter, case, strap Dual-purpose: source meter in one instrument Rugged design with usability for both bench and field work     Includes 9V Battery Calibration cable with spade lug terminals Carrying case Neck strap AC Power Adapter
