To Use The Constant Current Or Voltage Mode; To Adjust The Time - Fisher Scientific Midi300V/4 Instruction Manual

1. Place the power supply on a level, dry bench surface away from sources of
direct heat.
2. With the AC power switch in the OFF position, plug the power cord into a
grounded AC outlet of the appropriate voltage (i.e. 100V or 240V,
determined by the rating sticker near the AC cord on the back of the unit).
3. Switch on the power supply by pressing the ON/OFF button at the rear of
the power supply.
4. Connect the power supply cables from the electrophoresis unit by inserting
the red lead (+) into the red power supply output and the black lead (-) into
the black power supply output beneath the front fascia plate.
4.3 To use the constant voltage or current mode
* Press the
respectively.
5. Press the
1mA increments or decrements to the required output value.
6. After adjusting your constant mode output value (e.g. voltage), set the other
parameter to the maximum output (e.g. current).

7. After setting the desired current or voltage output value, press the
button, and then press
or buttons to set a constant voltage or current
or buttons to adjust the voltage or current in 1V or
