If the Electronic Load Does Not Turn On
Use the following troubleshooting steps to help solve problems you might encounter when turning
on the instrument:
1)
Verify that there is AC power to the electronic load.
First, verify that the power cord is firmly plugged into the power receptacle on the rear
panel of the electronic load. You should also make sure the power source you plugged the
electronic load into is energized. Then check to see that the electronic load is turned on.
2)
Verify the power line voltage setting.
The line voltage is set to the proper value for your country (110VAC or 220VAC) when the
electronic load is shipped from factory. Change the line voltage setting if it is not correct.
3)
Verify that the correct power line fuse is installed.
If fuse is blown, please replace it according to the following specification.
Table 1 - Fuse Table
Product Fuse specification (110VAC) Fuse specification (220VAC)
MDL001 T5A, 250V T2.5A, 250V
MDL002 T5A, 250V T2.5A, 250V
4)
Replace fuse.
Use a flat-bladed screwdriver to open the small plastic cover under the AC input connector
on the rear panel of the load and then replace with matching fuse.
