Shutter Speed Set the shutter speed to match the speed of movement of the measurement target and the lighting environment. The type of camera that is connected is automatically recognized, and only shutter speeds that can be set are displayed. List of Available Functions for Each Camera p. 151 MENU mode - [Setup] - [Cameras] - [Shutter Speed] Setting value 1/170 to 1/20000 s Description Fixes the shutter speed to the desired value. Only available candidate shutter speeds are displayed. The candidates differ with the camera that is connected and setup conditions. Note Guidelines for setting shutter speed Shutter speed characteristics are as follows. Select the appropriate shutter speed to suit your inspection requirements. Shutter Speed 1/170 s · 1/20000 s Speed of Movement of Measurement Target Slow · Fast Gain Setting The sensor's gain (sensitivity) can be adjusted if bright images cannot be obtained just by the Shutter Speed and Light Control settings. MENU mode - [Setup] - [Cameras] - [Gain] Setting value x 1. 0, x 1. 5, x 2. 0 Description Sets the gain factor. (default value) x 1. 5: The gain factor is set to 1. 5X. x 2. 0: The gain factor is set to 2. 0X. Note Guidelines for setting gain Increasing the gains results in a brighter image, however, the noise component contained in the image also becomes more conspicuous. Select the appropriate gain factor to suit your inspection requirements. Gain x 1. 0 · x 2. 0 Image Dark Bright Image Quality Good (little noise) Coarse (conspicuous noise) 84 Cameras/Lighting ZFX-C User's Manual Partial Function Settings Set the image capture area. Limiting the image capture area in this way speeds up processing. The items that can be selected by this function change according to the camera connected to the Controller and shutter speed conditions. List of Available Functions for Each Camera p. 151 Important When the partial function setting is changed, the size of the input image also changes. When the partial function setting has been changed, set the measurement conditions including the model conditions of measurement items and position shift compensation again. MENU mode - [Setup] - [Cameras] - [Partial Function] 3 Each selection of [Size] switches the image capture area in the following order: None (Full display) 1/2 display 1/4 display SETTING THE MEASUREMENT CONDITIONS Note Adjustment of Image Capture Area When 1/2 display or 1/4 display is displayed, the capture area can be adjusted up and down.
