Counter instruments in the Universal and Multi-Function Counters category can include a number of applications. These can include serial events, repetitive events and general frequency events. Since frequency is defined as the number of events of a particular sort occurring in a set period of time, it is generally straight forward to measure. Most frequency counters work by using a counter which accumulates the number of events occurring within a specific period of time. After a preset period the value in the counter is transferred to a display and the counter is reset to zero. The internal oscillator which enables the frequency counter to measure time is called the time base, and must be calibrated very accurately. Our universal and multi-functional frequency counters come with 365 days customer service when you have questions or need expert assistance.
