Note: 1. Hysteresis denotes the difference in forward LED 3. The following illustrations show the definition of response current value, expressed in percentage, calculated delay time. The value in the parentheses applies to the EE- from the respective forward LED currents when the SX498. photo IC in turned from ON to OFF and when the photo IC in turned from OFF to ON. Input Input 2. The value of the response frequency is measured Output by rotating the disk as shown below.
