indicates when the output current has reached its selected limiting value, i.e., the power
supply is operating in the constant current mode.

CURRENT Knob.

A large, multi-turn knob allows you to set the point of inception of

the constant current mode.

FREQUENCY Knob.

A large, multi-turn knob allows you to set the operating

frequency.

FAULT LAMP

When lit, this lamp indicates that a fault condition has been detected, and that the system
output has been turned off automatically.

Some conditions that cause this to occur include: output over-voltage, output over-current,
high internal temperature, changing the output voltage range while the output is turned on,
starting the system with the output turned on and the unit in power up to zero volts mode,
or an internal system failure.

SLAVE LAMP

When lit, this lamp indicates that the unit is operating in the slave mode.

OUTPUT ON LAMP

When lit, this lamp indicates that the output switch has been set to the on position, and
power is on the output terminals.

OUTPUT ON/OFF/RESET SWITCH

Located on the right side of the front panel, this switch allows you to energize the output
terminals of the power supply. If the unit is operating in the fault mode, and if the fault
condition has cleared, then cycling this switch will restore normal operation.
