EX Series Operating Manual
2-3. Output Check
The following procedures check to ensure that the power supply develops its rated outputs
and properly responds to operation from the front panel. For complete performance and
verification tests, refer to belows procedure.
Voltage Output Check
▌The following steps verify basic output voltage functions with no load.
1. Turn on the power supply.
2. The output is disabled (the OUTPUT OFF is displayed on the LCD)
3. In other to measure the voltage, connect the DVM to output terminals properly.
4. Press the "OUTP ON/OFF" key in other to output the voltage.
5. Press the "V/I LMT " key and move the under bar cursor to voltage value.
6. Press the left cursor move key and select the voltage resolution what you want.
7. In other to increase or decrease, turn the encoder switch CW or CCW.
8. Compare between LCD display real voltage value and DVM annunciator.
Current Output Check
▌The following steps check basic current functions with a short across the power
supply’s output.
1. Turn on the power supply.
2 The output is disabled (the OUTPUT OFF is displayed on the LCD)
2. The output is disabled (the OUTPUT OFF is displayed on the LCD)
3. Press the "OUTP ON/OFF" key in other to output the voltage.
4. Press the "V/I LMT " key and move the under bar cursor to current value.
5. Press the left cursor move key and select the voltage resolution what you want.
6. In other to increase the voltage to 5V, turn the encoder switch CW or CCW.
7. Press the right cursor move key and select the current resolution what you want.
8. In other to increase or decrease, turn the encoder switch CW or CCW.
8. In other to increase or decrease, turn the encoder switch CW or CCW.
9. In other to change to "OUTPUT OFF" mode, press the "Output On/Off" Key.
10. In other to measure the current, connect the DAM to output terminals properly.
11. Press the "V/I LMT " key and move the under bar cursor to voltage value.
12. Compare between LCD display real current value and DAM annunciator.
