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 operation icon “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 depending on the
resistance of the load (buffer concentration in the attached
electrophoresis tanks) up to a maximum of the mAmp current setting
that has been chosen.
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 operation MODE icon on the touch screen to change
parameter mode. “TIME” will start to flash to indicate that this
parameter can be adjusted. Press the UP/DOWN arrows to
change the TIME value.
Pressing MODE again will toggle to the next parameter that can be
set: VOLTAGE.
Adjust parameters (TIME, VOLTAGE, mAMP) as required for the
electrophoresis application.
