Programming the IEF100
Main Screen
When turned ON, the main screen is displayed (Fig. 10). The main
screen contains the following fields.
Date and Time
The date and time are set up at Pacific Standard Time. Use the
OPTION button to set the date and time for your location. (See
options screen page 17).
List of 30 Protocols
The first nine protocols are shown on the display. One of the proto-
cols is always highlighted. Use the knob to scroll through the other
protocols.
The instrument is preloaded with 9 protocols for focusing 7, 18 or
24 cm IPG’s. These are general guidelines for focusing. IPG strip
manufacturers normally give recommended focusing times in total
volt-hours (volts multiplied by hours). Both under and over focusing
can be problematic. Optimum focusing times should be determined
by the end user considering the IPG strip, the sample type and sample
protein load. All protocols can be overwritten, if desired.
In addition to these 9 protocols, there are 21 additional unnamed
protocols without preprogrammed steps, allowing the user ample
space to create custom protocols.
