A. Auto Step/Ramp Mode
The LC100 has the ability to step the mA output
in 25% steps automatically in 5 second inter-
vals. It can also ramp the mA output from 4 mA
to 20 mA then back to 4 mA in a linear fashion
automatically.
To activate the Auto-Step/Ramp mode use the
following procedure:
1) The Auto Step/Ramp function can be used in
either the source mA or simulate mA mode.
Place the LC100 in one or the other mode.
2) Connect the LC100 to the device under test.
