TIME AND FREQUENCY
Calibration Specialists provides a time calibration service for stopwatches and timers.
Proper calibration of today’s sophisticated timing test and measurement equipment is essential for preserving measurement accuracy, complying with international standards and sustaining your competitive advantage.
Frequency calibrations measure the performance of frequency standards. The frequency standard being calibrated is called the unit under test (UUT). In most cases, the UUT is a quartz, rubidium, or cesium oscillator. In order to perform the calibration, the UUT must be compared to a standard or reference.
The word comes from Greek τάχος (táchos “speed”) and μέτρον (métron “measure”). Essentially the words tachometer and speedometer have identical meaning: a device that measures speed. It is by arbitrary convention that in the automotive world one is used for engine and the other for vehicle speed. In formal engineering nomenclature, more precise terms are used to distinguish the two.
These frequency counters and counter timers are widely used within a variety of areas of electronics test to measure the frequency of repetitive signals, and also for measuring the time between edges on digital signals.
