Configuration Status Query
This advanced command may be used to verify the results of sending the commands mentioned
previously. It may also be used to check for faults in the TCM system or to check the present setting of the
manual controls on the front panel.
The charge and discharge of inductive loads may be monitored to determine when valid readings are
available and to check the cable disconnect status indicators.
Upon receiving the code E the 4300C will place into its output buffer a "configuration status word". The
status word is made available for the next read by the controller. No measurement data is available until
this word is read.
The word is in the format:
Q?V?I?SND?C?UHF
Where:
Q? reflects the present value of the SRQ command
V? reflects the present voltage range setting
I? reflects the present test current setting
S is the letter "S" if hold mode has been selected, or "T" if tracking mode is
selected
N is the letter "N" if normal mode has been selected or "A" if TCM is enabled
D? reflects the present value of the output data terminator command
C? reflects the Test Current status
U is the letter "U" if the 4300C senses that it is UNSAFE to disconnects
cables; an ASCII space character indicates SAFE
H is the letter "H" if the 4300C's charging inductor mode has been
activated; an ASCII space character indicates no charging inductor
F is the letter "F" if a fault is detected in the TCM sensing mode; an ASCII
space character indicates no faults
