Questions
Bench Multimeter (Precision) calibration FAQ
How often should a bench multimeter (precision) be calibrated?
Precision bench multimeters are typically calibrated every 12 months. Units used as in-house reference standards may be calibrated every 6 months to tighten the uncertainty budget.
Is bench multimeter (precision) calibration accredited?
Yes. Bench Multimeter (Precision) calibration is covered under our SAC-SINGLAS scope of accreditation (LA-2023-0845-C, ISO/IEC 17025), covering DC/AC voltage to 1020 V, DC/AC current to 30 A, resistance to 1200 MΩ and frequency to 2 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 bench multimeter (precision) 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 bench multimeter (precision) do you calibrate?
Commonly submitted brands include Keysight. 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.
