For the peak-to-peak hold function, the sampling period can be specified with the

combination of the trigger mode and delay time settings.

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

Timing diagram

■ External trigger mode

• The sampling period is between the UP edge of the timing input (hold-reset

input) and the UP edge of the next timing input.

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

output.

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

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