Programmable DC Power Supply 62000L Series User's Manual

2.2.2 Current Output Check

Through the following steps, you may check the basic current functions with a short on the
power supply's output.
1. Turn on the power supply: The power-on/reset state is running, the output is disabled (the
OFF light is on), and the knob is selected for voltage control.
2. Connect a short across the (+) and (–) output terminals with an insulated test lead.
3. Enable the output: Some symbols, such as OVP, OCP are lit, as well as the CV or CC
according to the resistance of the test lead. The blinking cursor can be changed by turning
the knob. Please note that the display is in the meter mode which means that the display
shows the actual output voltage and current.
4. Verify that the front panel ammeter responds to knob control within the
0~7A(62010L-36-7)/0~6A(62015L-60-6) range: Rotate the knob clockwise or
counter-clockwise to check whether the ammeter tracks the knob control and shows
nearly zero.
5. Make sure that the current can be adjusted within the 0~7A/0~6A range: Rotate the knob
until the ammeter shows 7A/6A.

Input Power Check

This power supply can operate properly using a 115V or 230V single phase AC power source
at 50Hz to 60Hz. The rear panel shows the nominal input voltage set for the power supply at
the factory. If need be, the power-line voltage setting can be changed according to the
instructions as shown in "Power-Line Voltage Selection" below.

2.3.1 Power-Line Cord Check

A power-line cord, which has an appropriate plug for your location, is shipped with the power
supply. If a wrong power-line cord is included with your power supply, contact your local
distributor.
This power-line cord consists of a 3-wire grounding type power lead where the third conductor
is the ground. You should ground the power supply by plugging the power-line cord into a
proper outlet. Please do not operate this equipment without effective grounding facilities.

2.3.2 Power-Line Voltage Selection

To select the power-line voltage, you have to adjust two components, including the power-line
voltage selector and the power-line fuse. They are located on the power-line module on the
rear panel.
When you want to change the power-line voltage, please proceed as follows.
1. Remove the power cord: Use a flat-blade screwdriver to remove the fuse-holder assembly
from the rear panel.
2. Install the correct line fuse: Take out the power-line voltage selector from the power-line
module and install the correct fuse
