Description:

1. The YC99T - 5C is a portable three - phase meter testing device (calibrator) suitable for both laboratory and on - site use. Leveraging the latest advancements in energy meter calibration technology, this calibrator offers high - precision testing capabilities.
2. It shares the same software functionality as the YC99T - 5C calibration system but differs in voltage and current output. The YC99T - 5C calibrator supports the DLT - 645 (2007) communication protocol, enabling it to conduct comprehensive multi - function tests, including demand indication error, demand period error, time switching error, and rate period energy indication error.
3. Equipped with a constant - temperature crystal oscillator, the YC99T - 5C can accurately verify the daily time error of electric energy meters. Its design features an excellent panel screen and a well - organized wiring arrangement. Both the front and rear panels are user - friendly, facilitating easy operation.
4. Beyond normal meter testing, the YC99T - 5C can also serve as a harmonic power output device, generating stable harmonic outputs. It has similar functions to the YC99T - 3C, but they differ in voltage and current output. The YC99T - 3C offers more current and voltage channels.

Key Features:

1. Testing Modes: Supports both active power and reactive power testing.
2. Meters Under Test: Compatible with 3P4W, 3P3W, and 1P2W meters.
