ST2515 Operation Manual
67
Where,
<Reference Resistance> = 0 to 110E+6 (NR3) the reference resistance of the
comparator function, unit: ” Ω”
For example: WrtCmd(“COMP:REF 20E+3”); Set the reference resistance of the instrument
comparator function as 20kΩ.
Query Syntax: COMParator: REFerence?
Return format: the format and unit of <Reference Resistance><NL^END> are the same as above.
The :COMParator:PERCent command sets the tolerance of the instrument comparator function.
The :COMParator:PERCent? query returns to the current tolerance.
Command syntax:
COMParator:PERCent<Tolerance(%)>
Where, <Tolerance(%)> = 0 to 99.999 (NR2) the tolerance of the comparator
function, unit: ”%”
For example: WrtCmd(“COMP:PERC 10”); Set the tolerance of the instrument comparator
function as 10%.
Query Syntax: COMParator: PERCent?
Return format: the format and unit of < Tolerance(%) ><NL^END> are the same as above.
The :COMParator:RESult command querys the last comparator result of the instrument.
Query Syntax: COMParator: RESult?
Return format: < HI, IN, LO, OFF or ERR> <NL^END>
Where,
HI: it indicates that the measurement result is greater than the upper boundary of the
comparator
IN: it indicates that the measurement result is between the upper and lower boundary of
the comparator
LO: it indicates that the measurement result is less than the lower boundary of the
instrument
OFF: it indicates that the comparator function is “OFF”
ERR: it indicates that the comparator function is “ON”, but there exists the measurement
error.
7.1.8
BIN Subsystem Commands
BIN subsystem commands sets the bin comparator function of the instrument, including bin
status switch, beeper mode, limit mode, enable mask and other bin parameters.
