Function
Displays the grid bias voltage for the image
area in the three digit indicator.
(Grid bias voltage can be changed by using
"+ " & "–" ["up" & "down"] keys in 5V steps.)
Displays the grid bias voltage for the ID sensor
pattern in the three digit indicator.
(Grid bias voltage can be changed by using
"+ " & "–" ["up" & "down"] keys in 5V steps.)
Displays the PWM value for the high voltage
supply board [T] (transfer corona) in the three
digit indicator.
(The PWM value can be changed by using the
"+ " & "–" ["up" & "down"] keys in 1 step.)
Displays the PWM value for the high voltage
supply board [D-ac] (separation ac corona) in
the three digit indicator.
(The PWM value can be changed by using the
"+ " & "–" ["up" & "down"] keys.)
Displays the high voltage supply board [D- dc]
(separation dc corona) in the three digit
indicator.
(The PWM value can be changed by using
"+ " & "–" ["up" & "down"] keys.)
Displays the ID sensor output in the three digit
indicator.
(When entering this mode by pressing the "# "
key, the adjusted PWM value for the ID sensor
is displayed.
Hold down the start key to display the ID
sensor output voltage.
The PWM value can be changed by using the
"+ " & "–" ["up" & "down"] keys.)
Displays the V sensor output in the three digit
indicator.
(When entering this mode by pressing the "# "
key, the adjusted PWM value for the V sensor
is displayed.
Hold down the start key to display the V sensor
output voltage.
The PWM value can be changed by using the
"+ " & "–" ["up" & "down"] keys.)
