Questions
Analog Multimeter calibration FAQ
How often should a analog multimeter be calibrated?
Analog multimeters should be calibrated at least every 12 months. Instruments used in critical applications may need 6-monthly checks.
Is analog multimeter calibration accredited?
Yes. Analog Multimeter 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 and resistance to 1200 MΩ. 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 analog multimeter 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.
Can you calibrate my brand of analog multimeter?
Almost certainly — the makes listed on this site are simply the ones customers most commonly send in. Send us the make and model and our engineers will confirm whether it falls within our accredited scope or can be calibrated as a traceable service.
