sink current is 5A, and the instrument is working In CC mode. If Sink Res is
set to 20Ω, the sink current is 4A, which is within the limit of Is, so the instru-
ment works in CR mode at this time.
4.4.4 Set the Output-On/Output-Off Delay
You can set the output-on/output-off delay time within the range from 0 seconds
to 60 seconds.
• On Delay: Indicates from the time that a command to turn on the output is re-

1. Press the composite keys [Shift]+[V-set] (Config) on the front panel to enter
the configuration menu.
2. Rotate the knob to select On Delay or Off Delay, and press [Enter] to
