6.3 Constant Voltage / Constant Amperage
The myVolt Touch can be set to run with constant voltage or
constant amperage output, with the non-constant parameter set as a
limit.
Press the box “CONSTANT …” to switch between “CONSTANT
CURRENT” and “CONSTANT VOLTAGE” running modes.
In constant voltage mode, the power supply will output the set
voltage, and the mAmp current value will fluctuate (“float”) depending
on the resistance of the load, up to a maximum of the mAmp current
setting that has been chosen. The buffer concentration and size of
the electrophoresis gel box will dictate the resistance.
6.2 Setting Parameters
The myVolt Touch Power Supply has 3 main parameters that can
be adjusted: Run Time (TIME), Voltage (VOLTAGE), and Current
(mAMP).
(See section 7 for an overview of Voltage, Current, Resistance, and
Power)
Press the parameter box to adjust the value. The selected
parameter box will be highlighted. Press the UP/DOWN arrows to
change the value.
Adjust parameters (TIME, VOLTAGE, mAMP) as required for the
electrophoresis application.
