OPEN 1. Connect external power supply PS1 to #68, external power supply PS2 to TP1, and set PS2 to 0 V.
2. Set dark area static Y γ gain [1C] to 0dB [17], and bright area static Y γ gain [1C] to 0dB [17].
3. Increase PS1 from V
4. Set light area static Y γ gain [1C] to MAX [04].
5. Increase PS1 from V
6. Measure VLGP using the following figure, and PLGP using the following equation.
