10. Change the PWM value displayed in the three digit indicator by using the
number keys as follows:
To increase the corona current (absolute value): increase the PWM value.
To decrease the corona current (absolute value): decrease the PWM
value.
NOTE: You may use the following rule as reference:
Changing the PWM value by 6 will change the separation ac
corona current by about 1µA.
11. Press the enter key.
12. Repeat steps 4 to 11 until the proper separation ac corona current is
obtained.
13. Select the dc 200µA range on the digital multimeter.
14. Enter "9" (output check) using the number key and then press the enter
key.
15. Enter "8" (high voltage supply - separation corona); "8" will blink in the
three digit indicator.
16. Press the start key and read the separation dc corona current on the
digital multimeter when it is stabilized.
17. Press the clear/stop key to turn off the separation corona current, then
the enter key.
18. If the separation dc corona current is out of the adjustment standard, do
the following steps.
19. Enter "164" (D-CH(DC) PWM) by using the number keys then press the
enter key.
20. Change the PWM value displayed in the three digit indicator by using the
number keys as follows:
To increase the corona current (absolute value): increase the PWM value.
To decrease the corona current (absolute value): decrease the PWM
value.
NOTE: You may use the following rule as reference:
Changing the PWM value by 100 will change the separation dc
corona current by about 1µA.
