period

• Triggered by the acknowledgment of timing input, the measured value will be deter-

mined with an elapse of the sampling period (i.e., reset time).

• The strobe output time can be changed.

Refer to Strobe Output Time on page 4-48 for detail.

• The sampling period (i.e., reset time) varies with the averaging number.

Refer to Reset Time and Refresh Cycle on page 6-13.

• If RESET input or ZERO input is ON during the sampling period, the sampling will be

interrupted and the LS-7000 Series will await the result of measurement.

• Triggered by the acknowledgment of the workpiece, the measured value will be

determined with an elapse of self-timing and sampling periods (i.e., reset time).

• The self-timing period is adjustable between 1 and 9,999 ms.

Refer to Self-timing Hold Setting on page 4-42 for detail.

• The strobe output time can be changed.

Refer to Strobe Output Time on page 4-48 for detail.

• The sampling period (i.e., reset time) varies with the averaging number.
