Current Ranges (Low, High)
Current can be programmed in either of the two ranges, low range and high range.
The low range provides better resolution at low current setting. If any value is over the
maximum of low range, you must select the high range. Press the MODE key first,
then use the UP or DOWN key to select the current range.
MODE SELECT
CCL
Select Static Constant Current low range
MODE SELECT
CCH
Select Static Constant Current high range
MODE SELECT
CCDL
Select Dynamic Constant Current low range
MODE SELECT
CCDH
Select Dynamic Constant Current high range
Select range by pressing the ENTER key.
Changing the mode or the range affects the module. Both cause the input to go
through an off state. If the CC mode of Load module is active, the new setting will
immediately change the input at a rate determined by the slew rate setting.
STATic/DYNAmic Functions
In CC mode two operation functions (STATic, DYNAmic) can be selected. 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
states A and B use the same range. You can select A (CCL1 or CCH1) or B (CCL2 or
CCH2) through the A/B key on the module’s keypad or Mainframe keypad when level1
(A) or level2 (B) changes. Slew rate determines the rate at which Load level changes
from one load level state to another. Figure 3-3 shows current level of load module
after pressing of A/B key.
