Setting the Current Limit (I-Set)

You m ay 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. Use the numeric keys and push Enter to set the voltage limit. You can also use the up, down, right, and left arrow keys.

Save and Recall Setups (SAVE and RECALL)

You can store up to 20 different setups in setup memory l ocations (1 to 20). Each setup includes the set voltage limit, the

set current limit, and the maximum output voltage value. When shipped from the factory, setup memories 1 through 20

are empty. Save and recall setups as follows:

Saving setups.

1. After you set up the power supply (voltage limit, current limit, and the maximum output voltage) push the Save button.

2. Use the number keys or the arrow keys to select the setup memory (1 to 20) that you want to store the values in.

3. Push Enter to conﬁrm the memory location.

Recalling setups.

1. Push Recall.

2. Use the number keys or the arrow keys to select the setup that you want to recall.

3. Push Enter.

Set the Maximum Voltage (>MAX VOLT)

This control determines the maximum voltage that you c an set using the V-set control. This can help keep accidental

over-voltage from being applied to sensitive loads. To set the maximum voltage, follow these steps:

1. Push Menu.

2. Use the down arrow key to select Max Volt.

3. Push Enter and use the number keys to enter the voltage value.

4. Push Enter to turn on the maximum voltage feature. Limit Done should appear brieﬂy and then Max Volt will appear.

5. Push Esc to exit the menu.

6. Push V-Set.

7. Use the numeric keys or the arrow keys to change the voltage value. The value must be less than the maximum

voltage output.
