9.0 Operating Instructions
9.1 Constant Operation Protocol
The Constant Voltage, Current (250V and 300V), or Power Mode (250V Only) 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 Labnet Enduro™
Power Supplies.
A basic Constant Voltage, Constant Current, or Constant Power operating procedure of the Labnet
Enduro Power Supplies is provided below. We recommend reading the guidelines provided in this
manual for best results before starting an operation. The figures in section 9.1 are examples from
the 300V display screen. Please note that the 250V model has the same functionality herein with the
addition of constant power as viewed within the NOTE section of 9.1.
1. Press the Power Switch on the rear side of the instrument to turn on the Labnet Enduro Power
Supply. Upon start-up, the Display Screen on the front of the instrument will illuminate. The factory
default settings (or last settings used) will be displayed.
300V
TIME:00:00
AMP:400mA
The chosen constant parameter (Voltage or Current) is displayed in bold on the left side of the
display.
The Timer is the first line on the top right, and the non-constant value is displayed in the second
line on the right side of the display screen.
2. Press Constant button to choose constant volt or amperage.
Choosing constant VOLT, the VOLT setting will be large. Amperage defaults to “maximum setting”
and TIME will be “0”.
300V
TIME:00:00
AMP:400mA
Choosing constant AMP, the AMP setting will be large. VOLT will be “maximum value” and TIME
will be “0”.
400mA
TIME:00:00
VOLT:300V
3. Press Mode to choose the large VOLT/AMP value on the left side of the display. VOLT/AMP is blinking,
press the Up or Down Arrow to increase or decrease value.
NOTE:
Parameters will blink for 5 seconds.
After 5 seconds, if you don’t press any button, the parameters will stop blinking and the value will be
entered.
400mA
TIME:00:00
VOLT:300V
4. Press Mode. TIME is blinking, press the Up or Down Arrow to increase or decrease value. Time set to
00:00 means “continuous”, and the timer will count up. Time can be set for 00:01 to 99:99. The timer
will count down until the time is up and then stop the power supply.
400mA
TIME:00:00
VOLT:300V
5. Press Mode. Smaller AMP/VOLT on the right side of the display is blinking, press the Up or Down
Arrow to increase or decrease the value.
400mA
TIME:00:00
VOLT:300V
6. Press Start/Pause to start the power supply. The parameters will stop blinking and the “run” LED will
illuminate. “CONSTANT VOLT/AMP” will show on the display.
