B OPEN 1. Set black stretch point 1[18] to OFF (00).
2. Input signal of 0.7-V picture period amplitude to #68, and measure #12 picture period amplitude VB [V].
3. Set black level correction [18] to ON [04], determine DC change VBLC [V], and calculate BLC [V] using the
following equation
BLC = (VBLC/VB)] × 100 [(IRE)]
