Application Examples of Stopwatch Meters
| Stopwatch Mode |
 |
The stopwatch mode is used to time single events between start and stop pulses on the same channel. Duration of a single wave shape 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 relays in a Laureate panel meter, counter, or transmitter. 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. |
| Replacing an Oscilloscope with a Laureate Meter or Transmitter |
 |
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 or transmitter 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 and transmitters: elapsed time, number of pulses, pulse width, pulse separation, duty cycle, and pulse rep rate. |
