Constant Operation Protocol
Introduction
Instructions for operating the 300 Volt Hi Amperage Power Supply in the Constant
Operation are provided in this section. The Constant Voltage, Current, or Power
Mode allow you to specify a voltage limit, current limit and power limit to be used
during the entire duration of electrophoresis. Review the guidelines provided in this
manual before starting electrophoresis using the 300 Volt Power Supply.
A basic Constant Voltage, Current Mode, or Constant Power operating procedure
of the 300 Volt Power Supply is provided below. We recommend reading the
guidelines provided in this manual for best results before starting an operation.
1. Use the power switch on the rear side of the instrument to turn on the 300 Volt
Power Supply. On Display Screen Constant Mode and Program Mode will
appear.
2. With the Constant Mode highlighted press the Mode key
3. Use the Mode Key to navigate to needed parameter (Volt. Amp, or Wat)
4. Use the ▼▲ arrow keys to set either voltage (VOLT)) or current (AMP) or Power
(WAT) to the appropriate values.
5. Use the Mode key to select TIME and use ▼▲ arrow key to set the time
(hours/minutes) to specify the duration of the electrophoresis.
6. Press the CONSTANT key to select, Constant Voltage Operation, Constant
Current Operation or Constant Power Operation from the Display Screen.
7. Press START/PAUSE key to start electrophoresis.
8. Press the START/PAUSE key again to temporarily interrupt power to ongoing
electrophoresis without terminating the operation along with LED flashing.
9. Press the STOP key to stop electrophoresis.
