■ Flicker mode
• When the power is turned ON or the hold-reset signal is input, the display
shows "----" until the first measured value is determined.
• The internal timing signal is input once at every flicker time and the measured
value at the instant is displayed/output.
Average measurement function [b-2]
Calculates the average of the measured values during a specified period (sampling
period).
For the average 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 sampling period is between the UP edge of the 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 start the measurement again, short-circuit the hold-reset and GND
terminals.
