5.1.9.

CC Indicator LED (Ref 9)

Indicates the unit is in CC (Constant Current) mode. The power supply regulates the output
current at the selected value, while the voltage varies with the load requirement. Display is
active in local and remote

5.1.10. Output Current Control (Ref 10)

The local current set control is a lockable analog 10-turn potentiometer with precision dial, for
setting the output current from 0.1% to 100% of rated. This control will only operate in local
mode, if the supply is operated in remote mode the local current set control has no effect.

5.1.11. Current Display (Ref 11)

The Current Display is a 4½ digit LED indicator showing the current measured at the power
supply output. This display flashes and displays the programmed output current after the Set
Value button is depressed. Display is active in local and remote

5.1.12. Power Switch (Ref 12)

AC Power Switch. Provides two pole isolation from mains network.

5.1.13. HV ON LED (Ref 13)

Indicates the HV output is turned ON and potentially hazardous voltage may be present.

5.1.14. HV ON/OFF Button (Ref 14)

Turns HV Output ON/OFF (does not disconnect the HV output when OFF).

5.1.15. NEG LED (Ref 15)

When illuminated indicates the main output terminal polarity is Negative with respect to the
HV return. Only active if the reversible polarity option is installed.

5.1.16. POS LED (Ref 16)

When illuminated indicates the main output terminal polarity is Positive with respect to the
HV return. Only active if the reversible polarity option is installed.

5.1.17. Polarity Button (Ref 17)

Controls the output polarity of the supply. If the polarity switch is activated when the HV
output is ON, the supply turns the HV off momentarily, and then automatically turns HV ON
after the polarity has been switched. Only active if the reversible polarity option is installed.

5.1.18. Local LED (Ref 18)

Indicates that a supply equipped with remote analog or digital interface is operating in Local
control mode.

5.1.19. Local Remote Switch (Ref 19)

Toggles control mode of a supply equipped with remote analog or digital interface supply
between Local or Remote.

DO NOT DEPRESS THE HV ON PUSH-BUTTON UNLESS A
SUITABLE LOAD IS CONNECTED TO THE POWER SUPPLY'S
OUTPUT CABLE, AND THE LOAD IS CORRECTLY GROUNDED.
