VOLTAGE, CURRENT & RESISTANCE
Yenkay has got NABL accreditation (in accordance with the standard ISO/IEC 17025) in the Electro-technical field that covers all electrical parameters. We use Fluke, U.S.A. makes a Multi-Product calibrator that sources AC/DC Voltage up to 1020 V, AC/DC Current up to 20.5 A along with Current Coil up to 1000 A with multiple Waveforms as well as Resistance (up to 1 Giga ohm), Capacitance (up to 110 milli Farad), Frequency, AC/DC Power, Thermocouple & RTD simulation along with Oscilloscope calibration facility. It has got basic accuracy of 50 ppm.
Along with it, for measure parameters, we have 71/2 Digit Multimeter, which has got basic accuracy of 0.0018%. Additionally, the Current Transformer calibration is set up to 1200 A, 0.1 class accuracy. With this set up we can cover calibration of 6.5 digit Multimeters, Clamp meters, Oscilloscope, Function Generators, DC Load, Power Supply, Process calibrators, Handy calibrators, Portable calibrators, mV / mA sources, RTD simulators, LCR meters, Capacitance meters, Micro Ohm meters, Insulation Testers, Trimpots, Current Transformers etc.

ENERGY / POWER / HARMONICS
To give our client maximum satisfaction and reliable service, Yenkay always strive to add world class calibration set-ups. One of them is MTE-Switzerland make Portable Power Source, which sources out the three phase Voltage & Current with Phase Shifting of ±180°. The maximum Voltage output is 480 Volts between phase and neutral & Current output is from 100 mA to 120 A. All test values are generated absolutely synthetically with a high degree of accuracy & stability (0.03 %). The test can be performed @ 50 Hz & 60 Hz Frequency.
The values of Device under calibration are compared with the Reference Standard (make MTE-Switzerland) of accuracy class 0.05. The Scanner Head which comes along with Reference Meter is used to sense & count pulses & shows the Error measurement of meter under test.
