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.
