Getting Started WARNING. Observe all safety precautions listed in this manual before using this product and any associated instruments. Although some instruments and accessories would be used with non-hazardous voltages, there are situations where hazardous conditions may be present. This product is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety precautions required to avoid possible injury.
Getting Started 3. Connect the power cord that was provided with the instrument to the power connector on the rear panel. Connect the power cord plug to a properly grounded electrical outlet. 4. Push the power button on the front panel. To power off the instrument, push the front panel power button. WARNING. To satisfy safety requirements, always use load wires heavy enough not to overheat when carrying the maximum short-circuit output current of the power supply.
Getting Started Check the Output The following procedures check that the power supply develops its rated outputs and properly responds to operation from the front panel. Voltage output check. To verify basic voltage functions without a load, follow these steps. 1. Remove all leads from the output connectors. 2. Turn on the power supply. 3. Push Menu to bring up the Reset All menu. This menu allows you to set the instrument to default settings. 4. Push Enter. 5. Push the up arrow button to select Yes.
Getting Started 10. Push I-set and use the numeric keys and Enter button to set the current value to the maximum allowable for your current supply. Check if the displayed current value is approximately the same value as the maximum allowable. 11. Turn off the power supply and remove the short wire from the (+) and (-) output terminals. Cleaning Inspect the power supply as often as operating conditions require. To clean the exterior surface, perform the following steps: 1.

Operating Basics 4. 110 V/220 V selector switch Front-panel Operation Within a few seconds after powering on, the power supply goes into Meter mode. It displays the actual voltage and current output value. To see the voltage or current limits, press the Enter button. Pressing the V-Set or I-Set button puts the meter into Set mode. Both voltage and current limit settings will show, but either the voltage or current setting will flash to indicate which parameter can be adjusted.
Operating Basics Configuring the Instrument for Your Application The menu system includes settings like Max Volt that determines the maximum voltage output of the power supply and settings, like Out Recall and Save Last, that determine how the instrument initializes itself on power-up. This power supply features a constant voltage/constant current automatic crossover. This feature permits continuous operation in the transition from constant-voltage mode to constant-current mode as the load changes.
Operating Basics Setting the Current Limit (I-Set) You may set the current limit from 0 A to the maximum current value of each model. The maximum current rating is shown on the instrument name plate. 1. Push I-Set. 2. Use the numeric keys and push Enter to set the current limit. You can also use the up, down, right, and left arrow keys. Setting the Voltage Limit (V-Set) You may set the voltage limit from 0 V to the maximum voltage rating shown on the instrument nameplate. 1. Push V-set. 2.
Operating Basics 8. Push Enter. 9. Push Esc to exit the menu system. NOTE. The default maximum voltage is the full voltage range of the particular power supply being used. Recall the Power Supply ON/OFF Output State at Power On (>OUT RECALL) This parameter determines the initial On or Off output state after the power supply is powered on. If you select On, the power supply will restore the state of the output to that which was in use before the power was last turned off.
Operating Basics Set the Key Beep (>KEY BEEP) This control can switch on or off the sound that occurs when you push any button or press any key. To enable or disable this feature, 1. Push Menu. 2. Use the down arrow key to select Key Beep. 3. Push Enter. 4. Use the arrow keys to select On or Off. 5. Push Enter. 6. Push Esc to exit the menu system. NOTE. The default selection is set to Off.
