Modes Of Operation; Constant Current Mode - Chroma 63200 Series Operation & Programming Manual

3.5

Modes of Operation

There are four modes of operation: Constant Current (CC), Constant Resistance (CR),
Constant Voltage (CV), and Constant Power (CP).
You can select the mode by pressing
The parameters in current, resistance, voltage or power mode can be programmed easily when
the mode is selected.
All data set in CC/CR/CV/CP mode will be rescaled to fit the resolution of current/voltage
levels or slew rate. In local mode any value can be set to the Load from the keypad. There
is no upper and lower limit that would cause an error. The Load automatically selects data,
which is rescaled from the programmed value, truncates and checks high, low boundary
before fitting it into the memory. When the programmed data is over the boundary, the Load
will set the maximum or minimum level for it. In remote mode the programmed value
cannot be over boundary. An error will occur when data is over the maximum or minimum
value.

Constant Current Mode

In CC mode, the Load will sink a current in accordance with the programmed value
regardless of the input voltage. The CC mode can be set by
Press key to select the current waveform in Static mode. Static function checks the
A/B
stability of output voltage from a power supply.
Press key to select the current waveform in Dynamic mode. This key is only valid
DYNA
under CC mode, and Dynamic function checks the transient response.
Press key to select the current range suitable for your application no matter in static
RANGE
or dynamic current mode. Low range can supply better current resolution
