SECTION 1
OPERATION
1-1. OUTLINE
The BKM-20853 is a probe for automatic white balance
adjustment, designed to be used with Sony color
video monitors provided with Auto Set-up System.
Standard white stored at the factory
The color temperature of standard white, 6,500°K (for
North America and Europe) or 9,300°K (for Japan), is
stored at the factory.
Memory of three desired color temperatures
Memories 1 to 3 are available for storing color
temperature data extracted from a monitor. The
stored data can be used as reference white. (Memory
life: more than 100 years)
1-2. NOTES ON VERSIONS
The BKM-2053 comes in three versions which differ
with respect to factory stored color temperature and
the phosphor chromaticity used in the monitor CRT.
Confirm the version of your BKM-2053 described on
the nameplate.
Version

IC7 corresponds to D9300 (D6500) on menu and MEM-1 while
1C6 corresponds MEM-2 and MEM-3.
1C3 is decoder that provides the select signal selecting either R,
G or B.
The V.P signal is the vertical rate reference pulse in order to
generate the RESET pulse, that triggers one-shot IC8 and
generates
the

and
RESET
