Description:
- 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.
- 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.
- 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.
- 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:
- Testing Modes: Supports both active power and reactive power
testing.
- Meters Under Test: Compatible with 3P4W, 3P3W, and 1P2W meters.
- Power Source and Instrument Combination: The calibrator integrates
a power source and a calibration electronic instrument, providing a
wide range of current and voltage outputs.
- Special Tests: Enables starting tests and creeping tests.
- Data Management: Test data can be managed on a computer via the
Rs232 interface.
- Dual - mode Operation: Can be operated either directly on the
device or controlled remotely via a PC.
- Automated Calibration: Automatically calibrates energy meters,
covering multiple items such as preheating, starting, creeping,
error, influence, and quantity tests.
