Operation

1. Place the unit on a sturdy and level surface in a safe, dry place,
away from laboratory traffic.

2. Ensure that the AC power switch is OFF, and then plug the three­pronged power cord one end into a grounded three-prong AC
outlet with appropriate voltage (100V to 240V as indicated on the
rating sticker near the AC cord on the back of the unit) and plug the
other end into the main power socket.

3. Connect the DC output jacks from the electrophoresis unit; insert the
red lead (+) into the red output jack, and the black lead (-) into the
black output jack.

4. Power on the unit by pressing the ON/OFF switch on the back.

5. The screen will show a loading screen for few seconds then enter to
the mode-selecting page.

Constant Mode

Use the Constant Voltage / Current / Power Operation for applications that
require only one specific voltage limit, current limit, and power limit
continuously during the entire operation of electrophoresis.

Note: When target constant mode is set, system automatically adjusts the other two
parameters to maximum to allow constant run. For example, if constant voltage is set,
system will adjust current and power to the maximum value.

Users could later lower the other two values by themselves. System will hold the value either
at target constant value or the one which has been reached first

1. Use the up and down arrow keys to select
constant mode, then press the enter key to
move to the next page.
