Why calibrate?
Unitest calibrates multifunction electrical calibrators in Singapore — instruments that source and measure DC/AC voltage, DC/AC current, resistance and frequency — with SAC-SINGLAS accredited ISO/IEC 17025 certificates. Because these instruments are used as working standards, their calibration must be traceable.

Questions
Multifunction Calibrator calibration FAQ
How often should a multifunction calibrator be calibrated?
Multifunction calibrators are typically calibrated every 12 months. Heavily-used units may benefit from a 6-monthly interval.
Is multifunction calibrator calibration accredited?
Yes. Multifunction Calibrator calibration is covered under our SAC-SINGLAS scope of accreditation (LA-2023-0845-C, ISO/IEC 17025), covering voltage sourcing to 1000 V, current sourcing to 30 A, resistance sourcing 0.01 Ω to 10 GΩ and frequency sourcing to 100 MHz. Certificates state the measured values and measurement uncertainty, traceable to national and international standards. Where an instrument falls outside the accredited ranges, we can calibrate it as a traceable service instead.
How long does multifunction calibrator calibration take?
Standard turnaround is 5 to 7 working days; express service is 2 to 3 working days. Collection and delivery in Singapore are free for orders above $300.
Which brands of multifunction calibrator do you calibrate?
Commonly submitted brands include Druck, Fluke, IET, Martel Electronics, Mechanical Devices and Time Electronics. This list covers the models customers most often send in, not our full capability — send us your make and model and we'll confirm whether it falls within our accredited scope or can be calibrated as a traceable service.
