Operation Power Supply NGMO
4.00 / 07-2004 4-7
Example 1
line 1:
• "AS" means that currently the settings for channel A are displayed.
If you turn the output on by pressing the "OUTP. on/off" key the
display changes to "AM" indicating that this is now a measured
value taken from the output terminals of the selected power supply.
• x.xxx is the output voltage. If "AS" is displayed (output off) x.xxx is
the nominal voltage. If "AM" is displayed (output on) x.xxx is the
voltage measured on the sense lines of the output terminals.
• y.yyy is the current limit / output current. IF "AS" or "S" is display-
ed in front of y.yyy then y.yyy is the current limit setting. If "AM" is
displayed y.yyy is the actual current, measured on the force lines
of the output terminals.
line 2:
• A:OFF means that the output of power supply A is currently turned
off.
• A:ON means that the output of power supply A is currently turned
on.
• AB:OFF is displayed if function A/B24 "Common output on/off"
(see below Menu Items) is turned on and both outputs are off.
• AB:ON is displayed if function A/B24 "Common output on/off" (see
below Menu Items) is turned on and both outputs are on.
• PROT is displayed if the OCP key has been pressed so activating
the overcurrent protection function. In OCP active mode, the output
is switched off if the current on output lines exceeds the current li-
mit setting (y.yyy).
If OCP is turned off, the current is limited to the current limit setting.
If NGMO2 enters the current limit state "ILIM" is displayed at the
same location as "PROT".
"INH" is displayed at the "PROT" location when the output has
been turned off by a logical 1 applied to the INHIB_A pin on the
"CONTROL I/O" connector.
• RDY is displayed when the NGMO2 has finished sampling and
measurement data are ready to be transferred for analysis.
• REM is displayed when the NGMO2 has received remote com-
mands via the IEEE interface or serial interface. In remote mode
