LIA STATUS BYTE

The LIA Status bits stay set until cleared by reading or by the *CLS command.

usage
detected.
Set when a Time Constant filter overload is
detected.
Set when an Output overload is detected.
Set when a reference unlock is detected.
Set when the detection frequency switches
ranges (harmonic x ref. frequency decreases
below 199.21 Hz
203.12 Hz). Time constants above 30 s and
Synchronous filtering are turned off in the upper
frequency range.
Set when the time constant is changed
indirectly, either by changing frequency range,
dynamic reserve, filter slope or expand.
Set when data storage is triggered. Only if
samples or scans are in externally triggered
mode.
usage
Set at power up when the battery backup has
failed.
Set when the RAM Memory test finds an error.
Set when the ROM Memory test finds an error.
Set when GPIB fast data transfer mode aborted.
Set when the DSP test finds an error.
Set when an internal math error occurs.
