Current Sweep Output - Omega CA450 User Manual

3) Connect the lead cables to the positive (+) and negative (–) SIMULATE terminals.
(Connect the positive SIMULATE terminal to the positive terminal of the external DCV
power source. Make sure that the power source voltage is within  to 8 V.)
) Just as in SOURCE mode, use the output setting keys to set the sink current value.
(To enter span check mode, hold down %STEP▲ or %STEP▼ for one second or
longer.)
) Connect the lead cables to the circuit under test.
Press the SHIFT key again. "SIMULATE" disappears, and the CA450 returns to constant
current output (SOURCE) mode.
Tip
• If the set current is 0. mA or more and the terminals are open, "-----" appears in the
main display, and "----" appears in the subdisplay.

Current Sweep Output

You can make the output current (in SOURCE or SIMULATE mode) automatically fluctuate
between 0% and 100% of the current span setting.
) Turn the function switch to the "
After you turn the function switch, "OUTPUT" appears on the screen, and the output
starts rising from 0% of the current span setting.
(If you turn the function switch from the "
output value setting and SOURCE/SIMULATE setting are retained.)
2) Press the SHIFT key to select the current output mode (SOURCE or SIMULATE).
3) Press the SELECT key to select an output mode.
(When you change the output mode, the current starts rising from the value currently
being output according to the new mode.)
) After you connect the lead cables to the appropriate terminals for the output mode
(SOURCE or SIMULATE), connect them to the circuit under test.
Tip
• If you want to stop a current sweep that is being output, turn the function switch
