5.4 Running a program
Connect the leads from the electrophoresis unit (red to red, and black or blue to blue).
Red is positive and black or blue negative. Up to two electrophoresis units can run at the
same voltage at one time. Please remember to double the maximum current and power
conditions if two units are to be run. Voltage will be the same regardless of the number
of units. The current should also be doubled if two gels are run on the same unit.
Running a program is described schematically in Fig 7.
Choosing a program
Press SET ENTER and select the program you wish to run by pressing
/
until the
value is correct. (Omit this step if you have just programmed or edited a method as
described in sections 5.2 and 5.3.)
Running
Press RUN to start the electrophoresis. Information about the status of the start current
check will be displayed for a few seconds. The display will then show current values for
voltage, current and power and one of elapsed time, volthours or milliamperehours. You
can switch between showing the
elapsed time, volthours or milliamperehours by
/
.
The parameter controlling the electrophoresis is underlined.
A light emitting diode shows when voltage is applied (HV on).
If no current is displayed or if “HALT: Low start current” is shown, please check the
electrical connections to the electrophoresis equipment.
