The keypads on the module can perform simple functions like short, load on/off, static/dynamic, and load A/B or display selection R/L. Details of local operation are given in Chapter 4 Local Operation. Fundamentals of remote programming are described in the High Speed DC Electronic Load 6330 Series Programming Manual. Modes of Operation There are three modes of operation: Constant Current (CC), Constant Resistance (CR), and Constant Voltage (CV). -
Page 30: Constant Current Mode
Programmable DC Electronic Load 6310 Series Operation & Programming Manual 3.5.1 Constant Current Mode Figure 3-3 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 the key in the front panel. - Page 31 Operation Overview STATic/DYNAmic Functions In CC mode two operation functions (STATic, DYNAmic) are available for selection. STATic function checks the stability of output voltage from a power supply. In some modules (single channel/module) there are two current levels (A or B) for static function. Both A and B states use the same range.

Page 33: Constant Resistance Mode
Operation Overview 3.5.2 Constant Resistance Mode Figure 3-6 Constant Resistance Mode In CR mode, the Load will sink a current linearly proportional to the input voltage in accordance with the programmed resistance. There is a double pole RC filter of input voltage, so the high frequency parts will be removed. -
Page 34: Constant Voltage Mode
The voltage and current range in CR mode is high range. Load Synchronization Chroma 6334/6332 multiple electronic load mainframes contain eight and four load channels respectively. The channel on/off and load timing change is important. You can set module change synchronously through the SYNC RUN in configuration setting. If a channel is set to SYNC RUN ON, it means the channel on/off or load level change is synchronized with other Load modules. -
Page 35: Measurements
Operation Overview Measurements Each module measures current and voltage of a UUT. The sampling rate is about 12 mS. Voltage and current measurements are performed with a 15-bit resolution of full scale ratings. Slew Rate & Minimum Transient Time Slew rate is defined by the change in current over time. A programmable slew rate allows a controlled transition from one load setting to another to minimize the induced voltage drops on inductive power wiring, or control the induced transients on a test device. -
