TEST CONDITIONS (DEF V_CC = 9 V, Ta = 25 ± 3°C, BUS DATA = POWER-ON RESET)
MEASUREMENT METHOD
Set the subaddress (0E) data to (F8). Change the subaddress (10) D₇ ~ D₄ so that the #22
parabola waveform is symmetrical.
Set the subaddress (10) D₃~D₀ to (0) and measure the amplitude of the #22 waveform V_{CR (0)}.
Likewise, when the subaddress (10) data are set to (F), measure the #22 waveform amplitude
V_{CR (F)}.
A
V_CR = V_{CR (F)} − V_{CR (0)}

Correction
Set the subaddress (14) data to (7F).
Set the subaddress (10) data to (00) and measure the vertical NF center voltage of the #25
waveform V_{C (00)}.
