| Stopwatch Mode |
 |
The stopwatch mode is used to time single events to one microsecond resolution between start and stop pulses on the same channel.
The width
of a single waveshape can be measured by tying the A and B channels together. |
| Timing Process Dynamics |
 |
The start and stop pulses used for timing can be generated by the dual relay board in a Laureate analog panel meter or digital counter. For instance, the start and stop pulse edges can be created as temperature passes two alarm setpoints, or as temperature cycles in a hysteresis control mode. |
| Rate Based on 1 / Time |
 |
The Extended stopwatch meter can be programmed to display highly accurate rate or speed based on time. For example photodetectors on Channels A and B can provide timing pulses as a fast-moving object breaks two light beams, and the meter can then display speed in engineering units such as ft/sec or m/sec. The display will be held until reset by an external control input. |
| Replacing an Oscilloscope with a Laureate Meter |
 |
An oscilloscope is great for viewing and timing pulses in a lab. However, in fixed installations where digital timing accuracy and control outputs are required, a low-cost Laureate time interval meter will be the instrument of choice. Resolution to 0.2 µs is feasible. |
| Instrumenting a Pulsed Laser System |
 |
| Some of the many possibilities in instrumenting a pulsed laser system with Laureate dual-channel counters: elapsed time, number of pulses, pulse width, pulse separation, duty cycle, and pulse rep rate. |
