EASYSENSE Q3+ and Q5+
used in an investigation e.g. the distance from A to B or the length of the interrupt
card.
For example:
Line 1 – What is
being calculated
Speed at A
Speed from A to B
Accel. at A
Accel from A to B
Timing options
Time at A
Timing starts when the signal at input A changes and
stops when the signal reverts back.
• With Light Gates it will be the time it takes for an object
to pass through the light beam.
• For a Push Switch it will be the length of time that the
switch is kept depressed.
• For Timing mats it will be the length of time someone
stands on the mat.
► Time at A
Time from A to B
Timing will start when a signal change is
detected at sensor A and stops when the
signal at B changes (so it measures the
time taken by an object to travel from
sensor A to sensor B).
