FETCh
6.1 FETCh[:IMP]?
Description Fetch the last measurement taken.
ery Syntax FETCh[:IMP]?
Returned Parameters The data got from the commands can be divided into three types accord-
ing to dierent 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: <pri-
mary 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 pa-
rameter is the temperature increment T), when existing outrange
or measurement error, the returned value is “+9.90000E+37”.
System status:
-1 No data in the buer 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: <pri-
mary parameter>, <secondary parameter>, <system status>; <pri-
mary parameter>= the measurement of the current primary param-
eter and the format is NR3 (when the temperature conversion func-
tion is enabled and on the measurement display interface, the pri-
mary parameter is the temperature incrementT), when existing
outrange or measurement error, the returned value is “+9.90000E+37”.
<secondary parameter>= the measurement of the current secondary
parameter and the format is NR3, when existing outrange or mea-
surement error, the returned value is “+9.90000E+37”. The system
status is the same as above.
3. There is no return value for other display page.
