Accurate Calibration: Supports demand indication error, demand period error, time switching error, rate period energy indication error, and other multi-function tests. Built-in constant temperature crystal oscillator ensures precise verification of daily meter time errors.
Wide Compatibility: Supports DLT-645 (2007) communication protocol and works with 3P4W, 3P3W, and 1P2W meters.
Flexible Testing Modes: Active power and reactive power testing, as well as starting and creeping tests for comprehensive meter evaluation.
Harmonic Output Capability: Can function as a harmonic power source, providing stable harmonic signals for advanced testing needs.
User-Friendly Design: Front and rear panels are intuitively arranged for easy operation. Operable directly on the device or remotely via PC.
Automated Calibration Process: Intelligent automation handles preheating, starting, creeping, error measurement, influence tests, and quantity tests, reducing manual work and improving efficiency.
Data Management: Test data can be managed and archived via RS232 interface for convenient record-keeping and analysis.
YC99T-5C offers similar functionality but with different voltage and current output suitable for medium-range calibration.
YC99T-3C provides more voltage and current channels, ideal for large-scale multi-meter testing environments.
