laboratory traffic.
2. Ensure that the AC power switch is OFF, and then plug the three-pronged 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.

selecting page.
4.3 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.

stages available for use; use to move down
for setting Stage 4-6, and to go back Stage
1-3.

17
ØPress Key to start electrophoresis. The LED
is lit, and the screen will show the real time
parameter values.
ØWhen parameters reach the assigned value, the
color would turn orange.
ØWhen the run is completed, operation stops with alarm and is
displayed on the screen. Press Key to terminate a timed run, and turn the AC
power OFF by the switch on the back.
Note: It would take a little time (about 5 seconds) for the unit to power off.

No AC power
ØCheck if PowerPro power supply is
plugged, or AC power source has
problem.
AC power cord is not
connected
ØCheck AC power cord connections at
both ends. Use the correct cords.
The fuse has blown ØReplace the fuse.
