ISO 17025 Accredited Instrument Calibration - Transcat Canada

A change is being implemented to the way accredited calibrations are being performed. These changes are a result of ILAC P14, ISO 17025:2017, and NIST’s Policy on Traceability all require that calibrations that do not include reported measurement uncertainties prevent the respective instrument from propagating traceability.Get price

Instruments Calibration Procedures | Calibration of Instruments

Linear InstrumentsNon-Linear InstrumentsDiscrete InstrumentsThe simplest calibration procedurefor an analog, linear instrument is the so-called zero-and-span method. The method is as follows: 1. Apply the lower-range value stimulus to the instrument, wait for it to stabilize 2. Move the “zero” adjustment until the instrument registers accurately at this point 3. Apply the upper-range value stimulus to the instrument, wait for it to stabilize 4. Move the “span” adjustment until the instrument registers accurately at this point 5. Repeat steps 1 through 4 as necessary to achieve good accuracy at both ends of the range An improvement over this crude procedure is to check the instrument’s response at several points between the lower- and upper-range values. A common example of this is the so-called five-point calibration where the instrument is checked at 0% (LRV), 25%, 50%, 75%, and 100% (URV) of range. A variation on this theme is to check at the five points of 10%, 25%, 50%, 75%, and 90%, while still making zero and span adjustments at 0% and...Get price

Circuit breaker - Wikipedia

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect low-current circuits or individual household applGet price
