EX Series Operating Manual
1-6. Check After Power On.
The power-on test includes an automatic self-test that checks the internal microprocessors
and allows the user visually to check the display. You will observe the following sequence
on the display after pressing the front panel power switch to on. And also keep the
ex-remote and voltage value is zero and current value is max value.OVP & OCP level are
g
set to maximum output value of instrument capacity and it is under the vigilance.

▌During displaying above procedure, the instrument is initialized by stored in non-
volatile memory.
▌Also the instrument runs automatic self-test below mentioned.
Connection test between front panel and connector.
Remote interface test
Check remote interface for PC communication.
Front panel test
Remote interface test
Check remote interface for PC communication.
Memory data confirm test
Check product information and related setting.
ADC H/W error test
Check error on ADC control condition.
Unregulated state test
Check output voltage floating state.
ADC/DAC calibration test
check ADC & DAC Calibration data state.
If the error occurs, alarm beeps and the error code is saved to volatile memory
automatically. You can read the error code by pressing error key.

Remote Interface default is RS232C and the rate is set to 9600 baud when the power supply is
shipped from the factory. TCP/IP Module is optional and bulit in type.When ordering, please request.
Note1
In case of "Last State", it is disable when the power supply is shipped from the factory. If you want to
use this function, it is able to use in "Factory Mode". Refer to "5-4. Last State"
If attached the option of remote analog controll board, output is set by setting value.
