Quick Start

2. After the fuse box is opened, you can see the fuse in it. Please replace

with a fuse of the same specification..

2.6 Output Checkout

The following procedures check to ensure that the power supply develops its rated

outputs and properly responds to operation from the front panel.

2.6.1 Voltage Output Checkout

The following steps verify basic voltage functions without load.

1. Turn on the power supply.

2. Enable the outputs

Press key to let the CV announciator turn on to light.

3. Set the voltage value

Set some different voltage values, then wait till the Meter mode to check if the

VFD displayed voltage value is the same as the set voltage value, and to check if

the VFD displayed current value is nearly zero.

4. Ensure that the voltage can be adjusted from zero to the full rated value.

2.6.2 Current Output Checkout

The following steps check basic current functions with a short across the power

supply’s output.

1. Turn on the power supply.

2. Disable the output

Press

On/Off

key to ensure that the output is disabled.

3. Connect a short across (+) and (-) output terminals with an insulated test lead.

Use a wire size sufficient to handle the maximum current.

4. Enable the output

5. Adjust the voltage value to 1.0 volt

Adjust the voltage to 1.0 volt to ensure the power supply is in CC operation mode.

The CC announciator will turn on.

6. Adjust the current value

Set some different voltage values, then wait till the Meter mode to check if the

VFD displayed current value is the same as the set voltage value, and to check if

the VFD displayed voltage value is nearly zero

Out on/off
