ST2515 Operation Manual
61
The [:IMP]? query returns ST2515’s last measurement result to its output buffer.
Query syntax: FETCh[:IMP]?
The data got from the commands can be divided into three types according to different functions
and display page.
1. On the measurement display page, compare display interface, bin display page and statistical
interface and the measurement function is one-parameter mode (functions are R, T, LPR):
Data format: <primary parameter>, <system status>;
<primary parameter>= the measured value of the current parameter and the format is NR3
(when the temperature conversion function is enabled and on the measurement display interface,
the primary parameter is the temperature incrementΔT), when existing outrange or
measurement error, the returned value is “+9.37”.
System status: -1
No data in the buffer zone.
0
Ordinary measurement data.
+1
Measurement status error.
2.
On the measurement display page, compare display interface, bin display page and statistical
interface and the measurement function is two-parameter mode (functions are R-T, LPR-T):
Data format: <primary parameter>, <secondary parameter>, <system status>;
<primary parameter>= the measurement of the current primary parameter and the format is NR3
(when the temperature conversion function is enabled and on the measurement display interface,
the primary parameter is the temperature incrementΔT), when existing outrange or
measurement error, the returned value is “+9.37”.
<secondary parameter>= the measurement of the current secondary parameter and the format is
NR3, when existing outrange or measurement error, the returned value is “+9.37”.
The system status is the same as above.
3.
There is no return value for other display page.
The FETCh:AUTO command sets the automatic mode switch to send each measurement result to
its output buffer.
Command syntax: FETCh:AUTO ON(1)
OFF(0)
For example: WrtCmd(“FETC:AUTO ON”); namely opening the automatic sending mode of each
