BASIC OPERATING
INSTRUCTIONS
Operation in
Constant Voltage:
1.
The electrophoresis chamber
should first be set up, then filled
with buffer and sample, before
plugging the chamber’s leads
into the appropriate positive
and negative 4 mm sockets
(14) on the power supply.
2.
Switch on the power supply
using the Power On/Off
switch (22). The main power
switch is marked with a 1 to
indicate on and a 0 to indicate
off. Once on, the Green D.C.
Output Off light (21) and
Yellow Actual Display light (17)
will be illuminated. The Volts
display (3), Milliamps display
(5) and Watts display (7) will
all indicate zero. The Time dis-
play (10) will indicate zero as
well.
3.
Gently press the Set Display
key (19). The actual switch itself
is located in the grey area
located immediately below the
word “Set” in the Set Display
key. When pressed, there will
be a tactile sensation, the
power supply will beep and
the Yellow Set Display (18) light
will be illuminated. Each key on

NOTE:
An alterntive procedure favored by some users is as follows:
Sample is withheld from the chamber until the power supply has been properly
adjusted and successfully started. Once the user has confirmed that the chamber and
power supply are both functional, the power supply is turned off and sample is
loaded. The power supply will remember its settings, so it can be turned on and start-
ed without further adjustment.
