Why calibrate?
Unitest calibrates ground bond continuity testers in Singapore over a range of 30 mΩ to 1.7 kΩ, with SAC-SINGLAS accredited ISO/IEC 17025 certificates. Ground bond testers verify that protective earth conductors have sufficiently low resistance — an error here is a shock hazard.

How often
How often should a ground bond continuity tester be calibrated?
Ground bond testers should be calibrated at least every 12 months, or whenever used for acceptance testing of electrical equipment under IEC 60950 or IEC 62368.
Accredited ranges
Ground Bond Continuity 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
Ground Bond Continuity Tester calibration FAQ
How often should a ground bond continuity tester be calibrated?
Ground bond testers should be calibrated at least every 12 months, or whenever used for acceptance testing of electrical equipment under IEC 60950 or IEC 62368.
Is ground bond continuity tester calibration accredited?
Yes. Ground Bond Continuity Tester calibration is covered under our SAC-SINGLAS scope of accreditation (LA-2023-0845-C, ISO/IEC 17025), covering 30 mΩ to 1.7 kΩ. 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 ground bond continuity 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 ground bond continuity tester do you calibrate?
Commonly submitted brands include SCS. 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.
