Constant Current Output (SOURCE mode)

) Turn the function switch to the "
After you turn the function switch, "OUTPUT" appears on the screen, and the output is
set to 0% of the current span setting.
(If you turn the function switch from the "
position, the output value setting and SOURCE/SIMULATE setting are retained.)
2) If "SIMULATE" is displayed, press the SHIFT key.
("SIMULATE" disappears, the CA0 switches to SOURCE mode, and current output

Tip
• Because the CA0 outputs current in SOURCE mode, it consumes more
current than in other modes. You can keep the current consumption down in
SIMULATE mode.
• Hold down the %STEP, COARSE, or FINE key to increase or decrease
each digit consecutively.
Output Values for Each Step
You can press %STEP▲ or %STEP▼ to increase or decrease the output by one step (25%).
You can check the step value (as a percentage) in the subdisplay. (The output current
appears in the main display.)
