[ 4 ] CONFIRMATION OF
KV and MA
1. Turn the main switch on and set the exposure time at 1 sec. and 60 kV, 3 mA.
2. Make an exposure and keep the exposure switch depressed continuosly after the exposure is over.
3. Keeping the exposure switch depressed, press kV selection switch twice. KV measured value
will be displayed on the LED window. This value should be 60
±
5 kV.
4. Keeping the exposure switch depressed, press mA selection switch twice. MA measured value
will be displayed on the LED window. This value should be 3
±
1 mA.
5. Release the exposure switch and change the setting to 70 kV, 6 mA.
6. Make an exposure and keep the exposure switch depressed continuosly after the exposure is over.
7. Keeping the exposure switch depressed, press kV selection switch twice. KV measured value
will be displayed on the LED window. This value should be 70
±
5 kV.
8. Keeping the exposure switch depressed, press mA selection switch twice. MA measured value
will be displayed on the LED window. This value should be 6
±
1 mA.
[ 5 ] CONFIRMATION OF EXPOSURE WARNING LIGHT & BUZZER
A. EXPOSURE WARNING BUZZER
1. Make an exposure and confirm that the exposure warning buzzer located within the sub controller
is activated during the entire exposure.
B. EXPOSURE WARNING LIGHT
Exposure warning light is located on the front panel of the sub controller,
1. Make an exposure and confirm that the warning light illuminates during the exposure.

] CONFIRMATION OF LINE VOLTAGE REGULATION
1. Make sure that main power switch is "OFF".
2. Set the range of digital multimeter at
3
00 VAC, connect probes of multimeter to L and N of the
3P terminal block in the main controller.
Do not touch the restriction plate (refer to Fig.3-3) with the probes of multimeter during
measurement, or a short circuit occurs.
3. Turn the main power switch on, and set the exposure time at 2.00 sec. with manual switch at
70kV,
6
mA.
4. Record the no-load line voltage (VN) indicated by the multimeter before exposure.
5. Make an exposure and record the load voltage (VL) indicated by the multimeter during exposure.
X-Radiation is generated for 2 seconds.
NOTE :
Read the multimeter when the value is stabilized (about one second after exposure started).
6. Calculate line voltage regulation R(%) in the formula below :
NOTE :
Line voltage regulation must not exceed the range of 0 ~ 5 % for 100, 110, 120V and 0 ~ 3
% for 220, 230, 240Vac. If it is greater than this range, the size of the power supply wires
must be increased. Refer to the power supply requirements outlined on page 5 to determine
the correct wire size necessary. If line voltage regulation is within the range, apparent
resistance of supply line can be considered to be in the range of value specified on page 2.
