Application Examples of Stopwatch Meters
Stopwatch Mode
Stopwatch mode of Laureate digital stopwatch transmitter 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
Timing process dynamics by Laureate digital stopwatch transmitter 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
Replacing an oscilloscope by a Laureate digital stopwatch 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
Instrumenting a laser system using Laureate timers and stopwatches
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.
