GENERAL
This product is a Safety Class 1 instrument (provided with a protective earth terminal). The protective features of
this product may be impaired if it is used in a manner not specified in the operation instructions.
Any LEDs used in this product are Class 1 LEDs as per IEC 825-1.
ENVIRONMENTAL CONDITIONS
This instrument is intended for indoor use in an installation category II, pollution degree 2 environment. It is
designed to operate at a maximum relative humidity of 95% and at altitudes of up to 2000 meters. Refer to the
specifications tables for the ac mains voltage requirements and ambient operating temperature range.
BEFORE APPLYING POWER
Verify that the product is set to match the available line voltage, the correct fuse is installed, and all safety
precautions are taken. Note the instrument’s external markings described under "Safety Symbols".
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cover must be connected to an electrical ground. The
instrument must be connected to the ac power mains through a grounded power cable, with the ground wire firmly
connected to an electrical ground (safety ground) at the power outlet. Any interruption of the protective (grounding)
conductor or disconnection of the protective earth terminal will cause a potential shock hazard that could result in
personal injury.
ATTENTION: Un circuit de terre continu est essentiel en vue du fonctionnement sécuritaire de l’appareil.
Ne jamais mettre l'appareil en marche lorsque le conducteur de mise … la terre est d‚branch‚.
FUSES
Only fuses with the required rated current, voltage, and specified type (normal blow, time delay, etc.) should be
used. Do not use repaired fuses or short-circuited fuseholders. To do so could cause a shock or fire hazard.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes.
DO NOT REMOVE THE INSTRUMENT COVER
Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be
made only by qualified service personnel.
Instruments that appear damaged or defective should be made inoperative and secured against unintended
operation until they can be repaired by qualified service personnel.

Front Panel Number Entry
Enter numbers from the front panel using one the following methods:
Use the arrow keys and knob to change voltage or current settings
NOTE: The output must be ON to see the displayed values change in Meter mode. With the
output enabled, this method changes the output voltage or current immediately.
Use the Function keys and knob to change the displayed settings
Use the arrow keys to edit individual digits in the displayed setting
Increments the flashing digit
Decrements the flashing digit
Moves the flashing digit to the right
Moves the flashing digit to the left
Enters the value when editing is complete
Use the Function keys and Entry keys to enter a new value
NOTE: If you make a mistake, use the Backspace key to delete the number, or press the Meter
key to return to meter mode.

CV Output 1 or output 2 is operating in constant voltage mode.
CC Output 1 or output 2 is operating in constant current mode.
Unr Output 1 or output 2 is unregulated.
Dis The output is OFF. Press the Output On/Off key to turn the output on.
OCP The over-current protection state is ON. Press the OCP key to turn over-current
protection off.
Prot Indicates that the output has been disabled by one of the protection features.
Press the Prot Clear key to clear the protection condition.
Cal Calibration mode is ON. Scroll to the Cal Off command and press the Enter key
to exit the calibration mode.
Shift The Shift key has been pressed.
Rmt The remote programming interface (GPIB or RS-232) is active. Press the Local
key to return the unit to front panel control.
Addr The interface is addressed to talk or listen.
Err There is an error in the SCPI error queue. Press the Error key to view the error
code.
SRQ The interface is requesting service.
Immediate Action Keys
Toggles the output of the selected output between the ON and OFF states.
When coupled, turns both output channels ON or OFF.
Activates front panel control when the unit is in remote mode (unless a Lockout
command is in effect).
Resets the protection circuit and allows the unit to return to its last programmed
state.
A toggle switch that enables or disables overcurrent protection.
