６-４-２ FVR adjustment in tube current each point adjustment mode
Ⅰ
Setting of tube current each point adjustment mode
Set to ON the DIP switch SW2-5 ( Measured value display mode ) SW3-8 ( Adjustment mode ) on the NEXSC
PCB, and turn on the power.
Press the chest scan key in the APR to enter the tube current each point adjustment mode.
(The LEDs on the chest scan key and the standard body key flicker.)
Ⅱ
Setting of tube voltage
Set the tube voltage to 40, 60, 80, 100 and 125V in turn, and perform the steps III to VI for each tube voltage.
Ⅲ
Setting of tube current
Set the tube current to 50, 63, 80, 100, 125 and 160 mA in turn, and perform the steps IV to VI for each tube
current.
Ⅳ
Exposure
Press the hand switch to perform exposure. When the measured tube current is displayed in the tube current
display unit, compare it with the preset value.
Ⅴ
Adjustment of FVR value
Press the remote control selection key to display the FVR value in the preset tube voltage display unit. To
change the FVR value, press the tube voltage setting keys. If the measured tube current is higher than the
preset value, make the FVR value smaller. If the measured tube current is lower than the preset value, make
the FVR value larger. Repeat the steps IV and VI until the measured value becomes survey value ( -15 % to
+5 % ) .
Ⅵ
Registration of FVR value
Press the program registration key to register the FVR value in each position. When this key is pressed, “record”
is displayed in the display unit and the FVR value is stored.
