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