FAQs
A channel on my 123B is off — fixable? Yes. Isolated-input and trigger faults are repairable, then the channels are recalibrated so measurements are accurate, with a NIST-traceable certificate.
Are the inputs recalibrated? Yes — both channels are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
