School of Electrical Engineering Calibration Laboratory
The School of Electrical Engineering Calibration Laboratory at Vellore Institute of Technology (VIT), Vellore Campus, is a premier facility dedicated to providing high-precision calibration services. The laboratory is formally accredited by the National Accreditation Board for Testing and Calibration Laboratories (NABL), ensuring that its operations meet rigorous international standards for technical competence. The laboratory operates in strict adherence to ISO/IEC 17025:2017, the global standard for the “General Requirements for the Competence of Testing & Calibration Laboratories”. The lab exemplifies precision, reliability, and excellence in calibration services. With certificate number CC-4371, our accreditation is valid until 04/12/2028, underscoring our commitment to maintaining global standards.
Calibration Scope and Capabilities
The facility provides comprehensive calibration services across two major disciplines: Electro-Technical and Thermal. All Calibration and Measurement Capabilities (CMC) represent expanded uncertainties at approximately a 95% confidence level.
- Electro-Technical Calibration (Source & Measure) The laboratory utilizes advanced equipment, including Fluke 8846A 6½ Digital Multimeter for measurement and Fluke 5502A Multiproduct Calibrator for sourcing.
- Direct Current (DC): Measurement and sourcing of DC Current (up to 20 A), DC Voltage (up to 1000 V), and Resistance (4-wire, up to 1090 MΩ).
- Alternating Current (AC): Calibration for AC Current and Voltage at frequencies of 45 Hz and 1 kHz, with ranges extending up to 20 A and 1000 V respectively.
- Resistances: Resistance – 4 wire, with ranges extending up to 1090 Mohm respectively.
- Frequency
- Capability: Measurement and sourcing of frequency parameters @ 3 V.
- Range: Covers a wide spectrum from 1 Hz to 100 kHz.
- Thermal Calibration
- Equipment Calibrated: RTDs, Thermocouples (with or without indicators/controllers), Digital Thermometers, Temperature Gauges, Switches, and Transmitters.
- Methodology: Uses Precision RTD Temperature Probes and a Dry Block Calibrator via the comparison method.
- Temperature Range: -25 °C to 150 °C.
