Key benefits Reliable dualoutput signal generation: provides 010 V voltage signals and 420 mA current signals with an accuracy of 0.01, covering common test and calibration needs. Easy observation and comparison: oneclick switch between voltage and current with simultaneous output so you can easily observe and compare changes in both signals. Durable, userfriendly control: aluminum alloy encoder knob offers smooth, precise operation and longterm durability. Compatible with 2, 3, and 4wire current configurations for flexible wiring. Clear power status: battery level is shown on the display for quick, ataglance monitoring. Core specifications and features Output signals: 010 V (voltage) and 420 mA (current) Accuracy: 0.01 Control: aluminum alloy encoder knob for precise adjustment Wiring compatibility: supports 2, 3, and 4wire current configurations Operation: oneclick switch between voltage and current with simultaneous output Power indicator: battery monitoring via digital display Operation and usage notes Power and display: Turn on with the battery switch. Press and hold the MODE button for 1 second; the digital display will flash and show the battery voltage for 5 seconds. Battery color indication (green > 90%, yellow > 40%, red 40%) helps you assess remaining power. Applications and practical scenarios Sensor and transmitter testing: generate precise 010 V or 420 mA signals to test input channels of controllers, PLCs, or data acquisition systems. Calibration and verification: use the dualoutput to calibrate and verify signal processing chains, ensuring consistency between voltage and current paths. Bench testing of measurement equipment: simulate realworld signal conditions and observe how instruments respond to simultaneous voltage and current outputs. This product maintains a professional, trustworthy design while delivering practical, easytouse functionality for engineers, technicians, and lab personnel. It stays true to the original specifications and capabilities, providing clear benefits without added embellishments.
