■ 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.

■ 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
