Chapter 4 Use of Data Processing Functions

■ Internal trigger mode (Example of internal trigger DOWN )

• The sampling operation starts when the sampling delay time elapses after the

measured value falls below the trigger level. When the sampling period elapses,

the internal timing signal is turned ON and the "limited bottom-dead-center

value" is displayed/output.

For the internal trigger down

operation, the trigger point is the instant when

the measured value exceeds the trigger level.

• If a comparator output disable input turns ON before the comparator operation,

the comparator output does not turn ON. Refer to page 50 for details.

• The instant when the sampling starts, the strobe output turns ON.

• Turning the strobe output from ON to OFF results in the off-delay of 2 ms for

updating the comparator output.

• The trigger level is factory-adjusted to the full scale.

Reference: To clear the measured value being held and to start the measurement

again, short-circuit the hold-reset and GND terminals.

signal is input, the display shows " " until
