Whether you're in the field or the lab, this device is ideal for sourcing and measuring milliamp signals with exceptional precision. Its intuitive design simplifies calibration tasks, offering a practical and efficient solution for maintaining system accuracy and reliability.

Key Features and Benefits of the mAcal Loop Calibrator:

• Precision Measurement and Sourcin: The mAcal Loop Calibrator sources and measures current up to 24 mA with an impressive accuracy of ± 0.05% of full scale. This level of precision ensures that your calibration processes meet industry standards and maintain the integrity of your instrumentation systems. Additionally, it can measure voltage from 0 to 45 VDC with an accuracy of ± 0.5 VDC, making it a versatile tool for various applications.
• User-Friendly Design for Efficient Operation: The calibrator features a large, easy-to-read display that clearly shows measurements in milliamp (to 0.001 mA), percentage, voltage, or time (seconds). Error codes for loop mismatch, reverse polarity, and over-range conditions are also displayed, ensuring users can quickly diagnose and address issues. The intuitive keypad is labeled for straightforward operation, providing one-key-one-function access to step functions and loop supply power. This design reduces the learning curve and enhances productivity by making everyday tasks quick and easy to perform.
• Long Battery Life and Versatility: The mAcal Loop Calibrator operates on four AA batteries, offering up to 200 hours of usage. This extended battery life is ideal for field technicians who need a reliable tool that can last through multiple calibration tasks without frequent battery changes. The push-button feature allows users to switch seamlessly between mA and percentage readings, catering to different user preferences and application requirements.
• Flexible Testing Options for Diverse Applications: The calibrator includes special fixed steps stored for easy testing of linear and flow transmitters or valve positioners. Users can choose between manual or automatic steps, with options for 10 or 30-second intervals between steps, providing flexibility for various testing scenarios. This functionality makes the mAcal Loop Calibrator suitable for a wide range of applications, including process control, instrumentation maintenance, and troubleshooting.
• Optimized for Best Operation Conditions: The input and output connectors are strategically placed away from the display and keyboard, ensuring optimal working conditions and preventing interference. This thoughtful design feature enhances usability and makes the mAcal Loop Calibrator a practical choice for professionals who demand accuracy and convenience in their calibration tools.
