NOTE: The unit of the returned voltage is V.
The :FREQuency? query returns the current frequency result in the set frequency range. Refer to MEASure
subsystem commands for the frequency range settings.
Query syntax: FETCh:FREQuency
？
Return format: <NR3><NL^END>
NOTE: The unit of the returned frequency is Hz. If the start point is overlapped with the end cursor
completely, then 9.9E37 will be returned.
The TIME? query returns the current time result in the set time range. Refer to MEASure subsystem commands for
the time range settings.
Query syntax: FETCh:TIME
？
Return format: <NR3><NL^END>
NOTE: The unit of the returned time is s.
The :STATistic? query returns the current statistic result.
Query syntax: FETCh:STATistic?
Return format: <NR1>, <NR1>, <NR1>, <NR1>, <NR1>, <NR1>, <NR1>, <NR1>, <NR1>, <NR1>,
<NL^END>
The returned data are in turn as follows: total test times and times of PASS, total test times for Area Size
comparison and times of PASS, total test times for Diff Zone comparison and times of PASS, total test times for
Corona comparison and times of PASS, total times for Phase Diff comparison and times of PASS. PASS rate can be
automatically calculated according to the returned data.
8.4.11 MEASure subsystem commands
The MEASure subsystem commands sets the measurement range of voltage, frequency and time. Figure 8-12
shows the MEASure subsystem command tree.
MEASure :VOLTage
<upper>,<lower>
:FREQuency <start>,<end>
:TIME <start>,<end>
Figure 8-12 MEASure subsystem command tree
The :VOLTage command sets the measurement range of voltage. The :VOLTage? query returns the current voltage
range.
Command syntax: MEASure:VOLTage <upper>,<lower>
Where,
<upper> is the upper limit of voltage, NR1 format, ranging from 1 to 255 without unit.
<lower> is the lower limit of the voltage, NR1 format, ranging from 1 to 255 without unit.
For example: WrtCmd( “MEAS:VOLT 1,199” ); set the voltage to range from 1 to 199.
NOTE: The lower limit must be less than the upper one; otherwise an error message will be displayed on the
system message line.
Query sntax: MEASure:VOLTage
？
Return format: <upper>,<lower><NL^END>
Both upper limit and lower limit are NR1 format.
