Chapter 4 Use of Data Processing Functions

Intermittent measurement function [b-1]

Measures the value at a specified instant.

For the intermittent measurement function, you can select the method to specify

the timing by the combination of the trigger mode and delay time.

➮

For the details of the trigger mode and delay time, refer to pages 69 and 70.

Timing diagram

■ External trigger mode

• The value measured at the instant when the timing input turns ON is displayed/

output.

Reference: To clear the measured value being held, short-circuit the hold-reset

and GND terminals.

■ Internal trigger mode (Example of internal trigger up

)

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

measured value exceeds the trigger level. When the sampling period elapses,

the internal timing signal is turned ON and the value at the instant is displayed/

output.

• For the internal trigger down

operation, the trigger point is the instant when

the measured value falls below the trigger level.

• 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.

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

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