Battery Voltage Drop Check Mode
This mode is to check the drop of battery voltage and the inverter operation
(VIN) when load is applied for exposure. Use this mode to check the battery
condition.
Procedures to display the battery voltage drop check mode
1.
Set on the battery voltage drop check mode.
Turn on the DIP switch SW3-8 on the NEXSC board first, and then turn on
the power of the unit. Then, press the Normal key and Waist Exposure key
on APR to start the battery voltage drop check mode. (LED of the Waist
Exposure key and Normal key blinks.)
Fig. 21 Example of the display of the battery voltage drop check mode
(exposure condition is displayed)
2.
Exposure
The exposure condition indicator displays inspection exposure condition
(80 kV, 160 mA, 100 msec).
Values are measured when 80 msec pasts after the exposure starts.
Perform exposure by pressing the hand switch. After the exposure,
measured tube voltage and tube current are displayed on the exposure
condition indicator.
(Measured tube voltage and tube current other than this mode are values
measured 20 msec after the exposure starts. Therefore, the values may not
match with the tube voltage and tube current measured in this mode.)
3.
Switching indicated values
By pressing the remote controller choosing key, exposure condition, battery
voltage on the plus side, battery voltage on the minus side, inverter
operation frequency voltage during exposure VIN, measured tube voltage,
and measured tube current are displayed in sequence.
(Battery voltage on the plus side and battery voltage on the minus side are
measured 80 msec after the exposure starts in this mode. They do not
match with the battery voltage measured by procedures described in B.5
Adjustment of the battery voltage detection circuit.)
