How often
How often should a insulation resistance tester be calibrated?
Insulation resistance testers are commonly calibrated every 12 months, or immediately after any overload or severe environmental exposure.
Accredited ranges
Insulation Resistance Tester calibration ranges & measurement uncertainty
The parameters, ranges and calibration & measurement capability (CMC) below are taken from our SAC-SINGLAS Schedule of Accreditation (LA-2023-0845-C, to ISO/IEC 17025). CMC is the smallest measurement uncertainty we can achieve under accredited conditions.

Questions
Insulation Resistance Tester calibration FAQ
How often should a insulation resistance tester be calibrated?
Insulation resistance testers are commonly calibrated every 12 months, or immediately after any overload or severe environmental exposure.
Is insulation resistance tester calibration accredited?
Yes. Insulation Resistance Tester calibration is covered under our SAC-SINGLAS scope of accreditation (LA-2023-0845-C, ISO/IEC 17025), covering 10 kΩ to 999.9 GΩ. 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 insulation resistance tester 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 insulation resistance tester do you calibrate?
Commonly submitted brands include Fluke, Hioki, Kyoritsu and Yokogawa. 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.
