If the parameters need to be changed during the run you must stop electrophoresis by pressing
the Mode key. Enter the changes and then press Start/Stop once again to restart your opera-
tion.
Note: After stopping and restarting an operation, the timer resets to selected time and does not take into
account the time that electrophoresis was in progress before it was stopped.
Basic Programming Protocol
Instructions for operating the peqPOWER 250 Volt Power Supply in the Programming Mode are pro-
vided 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, depend-
ing upon your electrophoresis needs.
A basic Programmable Mode operating procedure of the peqPOWER 250 Volt Power Supply is pro-
vided below. We recommend reading the guidelines provided in this manual for best results before
