A Stopwatch is a timepiece designed exclusively to indicate a time interval, with reference to measurement. It may be started and stopped at any given instant, and controlled by a start and stop mechanism. Excludes Timer as used to control, regulate, or register a fixed time interval which has been previously determined.

What is an Interval Timer?

An Interval Timer (TIMER,INTERVAL) is an instrument for signalling the expiration of a predetermined time. It may also have an automatic switch for control of electrical circuits See also TIMER, STOP.

What is a Stop Timer?

A Stop Timer (TIMER,STOP) is a precision instrument for measuring and indicating elapsed time periods. Not intended to be carried on the person. See also TIMER, INTERVAL.

What is a Wall Clock?

A Wall Clock (CLOCK,WALL) is a clock specifically designed for mounting on or in a wall. It may have chimes and/or strike features. It shall not have any mechanism for controlling and regulating secondary clocks or alarm signalling devices.

What is a Time Totalizing Meter?

A Time Totalizing Meter (METER,TIME TOTALIZING) is an instrument that automatically measured, and cumulatively registers the total operating or idle time of any circuit, machine or system, to which it is connected. See METER, FREQUENCY AND TIME TOTALIZING, ELECTRICAL.

What is a Panel Clock?

A Panel Clock (CLOCK,PANEL) is a clock specifically designed for mounting on or in a panel. It may have a strike mechanism. Excluded are mechanisms for controlling and regulating secondary clocks and alarm signalling devices.

What is a Sequential Timer?

A Sequential Timer (TIMER,SEQUENTIAL) is an item which actuates included electrical contacts and/or switches in an orderly succession, and at a predetermined interval(s) for the purpose of controlling the operation of another electrical device(s). May have provision for manually establishing an operational sequence or cycle. See also RELAY, MOTOR DRIVEN; TIMER, INTERVAL; KEYER (as modified); CHRONOMETER, MAKE-BREAK CIRCUIT and INTERVALOMETER (as modified).

What is a Time Code Generator?

A Time Code Generator (GENERATOR,TIME CODE) is a device specifically designed for use as a central timing device for the purpose of providing time-correlated signals for magnetic tape recorders, oscillographs, strip chart recorders, cameras, digital printers, remote digital displays or direct computer entry. The device may generate various time code formats, contain special features for time comparisons against broadcast time signals and provide visual display in BCD or decimal format.

NATO Supply Class 6645 refers to Time Measuring Instruments, which are categorized under NATO Supply Group 66 for Instruments and Laboratory Equipment.

Time Measuring Instruments in this class are used for measuring and indicating time intervals, durations, or specific points in time. These instruments are commonly used in various industries, including scientific research, manufacturing, aviation, and telecommunications.

Some examples of Time Measuring Instruments in this class include:

1. Clocks: These are devices that display the current time and are commonly used for general timekeeping purposes.

2. Timers: These instruments are used to measure and indicate specific time intervals or durations. They are often used in laboratory experiments, cooking, and sports events.

3. Stopwatches: These handheld devices are used to measure and record the time elapsed between the start and stop of an event. They are commonly used in sports, athletics, and scientific experiments.

4. Chronographs: These instruments combine the functions of a watch and a stopwatch. They can measure and record both the current time and elapsed time.

5. Time Recorders: These devices are used to record the time of events or actions, typically in a workplace setting. They are often used for attendance tracking and timekeeping purposes.

It is important to note that NATO Supply Class 6645 includes a wide range of time measuring instruments, each with its own specific features and applications. When selecting a time measuring instrument, it is essential to consider the intended use, accuracy requirements, and any specific features or functionalities needed for the task at hand.
