Chapter 4 Use of Data Processing Functions

Normal measurement function [b-0]

Displays/outputs the measured value continuously.

Timing diagram

* When the timing input is turned ON, the display and comparator output is held.

Peak hold function [b-1]

Measures the "maximum value" during a specified period (sampling period).

For the 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.

➮

For the details of flicker delay, refer to pages 70 to 73.

• 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.
