Basic Programming Protocol
Introduction
Instructions for operating the 300 Volt Hi Amperage Power Supply in the
Programming Mode are provided in this section. The Programmable Mode allows
you to vary levels in voltage (V), current (mA), and power (W) during specified periods
of time as discrete changes (STEP) for up to 10 steps, depending upon your
electrophoresis needs.
A basic Programmable Mode operating procedure of the 300 Volt Hi Amperage
Power Supply is provided below. We recommend reading the guidelines provided in
this manual for best results before starting an operation.
