TWO YEAR WARRANTY

All Elenco

models are guaranteed for two full years on all parts and service. For

the first 3 months, your power supply is covered at absolutely no charge. For the

remaining 21 months, a nominal service charge is required to cover shipping and

handling.

brief letter of explanation of problem, and sufficient packing material.

Before returning any merchandise please call our service department at

(847) 541-3800 to obtain a return authorization number (RMA).

Setting Current Limit

1. Set the ammeter range switch to the HI position (XP-605 only).

2. Adjust the current and voltage control knobs fully counter-clockwise.

3. Short the positive to the negative output terminal.

Press the power ON/OFF switch to ON. The CC LED should be lit.

5. Turn the voltage coarse knob clockwise 1/4 turn.

6. Set the maximum output current by turning the current coarse knob

clockwise.

Note XP605: If needed, set the amp meter range switch to the Lo position.

This now limits the output current to your setting.

FUSE REPLACEMENT

1. Unplug the power supply line cord from the AC outlet.

2. Unscrew the fuse cap and replace blown fuse with a new 4A, 250V
