3.4 Integral Time Delay Function

Set whether to use the integral time delay function or not. Explain how to set the integral time delay

function to usable state as follows.

The followings cases will result in measurement errors.

1. When measuring a light source with high duty ratio as well as high intensity

2. When periodically-changing light sources include very low intensity such as black

3. When cycles of a light source which are measured within the given integral time are not enough

Increasing the integral time is effective in decreasing the error. The integral time delay function

can be used to increase the integration time, to allow stable measurements.

☞

'2.5.4 Measuring a Frequency Light Source'

Use the following procedure to set the integral time delay:

1 Switch to the function mode to display [MEASURE]-

[Integ Delay ON/OFF].

☞

'3.1.2 Entering/Returning from the Function Mode'

2 Press the [CHANGE] switch.

3 To change the setting, press the [ROTATION] switch. ON/OFF is changed to each other.
