4.1.3 Status Indicator Lights
Four LED status indicators are located directly above the mains circuit breaker. These LED’s
correspond to the following conditions:
REMOTE The REMOTE LED indicates that the unit is in remote control
mode. If the IEEE-488 interface is used, this indicator will be lit
whenever the REM line (REMOTE ENABLE) line is asserted by
the IEEE controller. If the RS232, USB or LAN interface is used,
the REMOTE state can be enabled by the controller using the
SYST:REM command. Any time the REMOTE LED is lit, the
front panel of the MX Series unit is disabled. There is no LOCAL
button that allows the user to regain control of the front panel.
This prevents accidental change of settings in ATE applications.
OVERLOAD The OVERLOAD LED indicates an output overload condition.
This condition can be controlled by setting the current limit value
in the PROGRAM menu. Removing the load using the OUTPUT
ON/OFF button will recover from an overload condition.
OVER TEMPERATURE The OVER TEMPERATURE LED indicates an overheating
problem inside the unit. This is an abnormal condition, which will
cause the unit to shut off. Check the air openings to make sure
they are not blocked.
HI RANGE The HI RANGE LED is on when the high voltage output range
has been selected.
