Application Examples of Laureate Stopwatch Meters or Transmitters

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.
