三相電能表校驗儀

METES－電表測試系統
METES 系列為高精度電表測試系統，測量精度最高可達 0.05%，並具備寬廣的測量範圍，可用於單相與三相應用的精密量測。METES 系列電表測試系統主要用於感應式電表及電子式電能表在各種運轉條件下的精度測試。此外，在測試過程中，系統擾動因素例如諧波或閃變對電表量測結果的影響，也可以一併納入考量與分析。

METES - Meter testing
Meter test systems with high accuracies of up to 0.05% and a wide measuring range for precise measurements in single- and three-phase applications. The meter test systems of the METES series are used to test the accuracy of Ferraris meters and electronic electricity meters under any operating conditions. The impact of system perturbations such as harmonics or flicker on the meter can be taken into consideration during tests.
Three phase energy meter calibration verifier
Portable, three-phase energy meter calibration verifier. This unit is primarily intended for the verification of electronic and Ferraris energy meters, specifically aimed at the growing pre-payment energy meter industry in developing and first-world countries.
Energy Meter Verification
Full functionality for energy meter verification of calibration errors with direct percentage error read-out.
Instantaneous Measurements 
The unit measures and displays the system Voltage, Current, Angle and Power quantities. (W, var & VA) Per phase and total quantities.
Measurement Mode
The unit comes complete with three current clamp- on sensors for easy integration into the power network. The current clamp-on sensors have larger than usual installation maximum conductor diameter capability of 15 mm.
User interface
Easy menu driven interface for the entry of test parameters and display of test results using touch display.
Memory
This unit allows you to save all readings and test results in an on-board database for later downloading to the supplied PC software for report printing and archiving. Customer, Site and test results information is stored.
Printer (Optional)
This unit has an optional Bluetooth wireless printer for onsite printing of the test result. The printer is battery powered using rechargeable on-board batteries
