Section 1 Warning
Major Science Mini Pro 300V Power Supply has been tested and found to
comply with the limits for the CE regulation. Also, it is RoHS compliant to
deliver confident product which meets the environmental directive. These limits
are designed to provide reasonable protection against harmful interference
when the instrument series is operated in a commercial environment. This
instrument series used together with power supply unit generates, uses, and
can radiate radio frequency energy, and if not installed and used in
accordance with the instruction manual, may cause harmful interference to
radio communications. Operation of this instrument series in a residential area
is likely to cause harmful interference in which case the user will be required to
correct the interference at their expense. Changes or modifications not
expressly approved by the party responsible for compliance could void the
user’s authority to operate the equipment. It is strongly recommended for the
user to read the following points carefully before operating this equipment.
1. Read and follow the manual instructions carefully.
2. Do not alter the equipment. Failure to follow these directions could result
in personal and/or laboratory hazards, as well as invalidate equipment

*To set constant current, press , and LED indicator should light up.
6. Adjust the output value by pressing the or button.
7. After adjusting your constant mode output value, switch to the other
parameter and set it to maximum.
8. Timer Setting: After setting the current or voltage output value, press the
15
Timer button, and then press key or key to adjust timer
accordingly.
Note: When timer is set as “0”, it means continuous operation.
9. Press Key to start the run. Once the electrophoresis starts, the LED
