W Walking Threshold

W<CR> Read

Response Format: <N>

W<N><CR> Set

<N> is an integer from 0 to 999,999,999 that is the walking velocity value multiplied by 1000.

When valid velocity measurements are made below this value, the velocity output and pulse output will be forced to zero. When the velocity measurements are above this value, it has no effect. The LS8000-3 compares the absolute value of the measured velocity to this threshold. For example, say the W value is set to 1000, and the measurement units are feet/minute. If the LS8000-3 measures velocities between -1 and +1 feet/minute, it will output zero for the speed, and will not output pulses. If the velocity exceeds ±1 foot/minute, the LS8000-3 will output measurements normally.

Setting this value to 0 disables the threshold.

This setting is used to prevent the LS8000-3 from sending velocity measurements and pulses when the velocity is close to zero. If the product being measured is stopped, but vibrating, the LS8000-3 will measure small velocities, both positive and negative. This setting can be used to suppress those measurements.

Note: Changing this setting will cause a reset, will reset the indicated length, and will cause the pulse outputs to be momentarily interrupted. Do not change this setting during normal operation.

X Minimum Final Length

X<CR> Read

Response Format: <N>

X<N><CR> Set

<N> is an integer from 0 to 999,999,999 that is the minimum final length value multiplied by 1000.

When a final length measurement completes, and the measured length is less than this value, no final length will be transmitted over the serial port.
