the OK button to go on. If the Break button is clicked on the sequence will be stopped
and no voltage will be applied.
During the measurement each 2 seconds a measurement will be stored into the table.
When the measurement is done after the set measuring time then the results can be
accessed in a sequence by the function
GetMeasData
.
To release the DC HV source for another simultaneous running sequence (see chapter
9.6.2 Run two sequences simultaneously ) use the
DC_HVOff
procedure. It is
recommended always to use the
DC_HVOff
procedure after a DC Resistivity
measurement.
Sample:
var
DCVoltage: double;
DCTime : integer;
RE: double;
SampleName: string;
…
begin
DCVoltage:=200
DCTime:=60
SampleName:=’Oil Sample XXX’;
DC_Measure(DCVoltage, DCTime, SampleName);
RE:=GetMeasData(id_DCRES);
DC_HVOff;
…
end.
DC_Shorting(ASec: Integer);
This procedure shorts the plugs
“U” and “a” for the time <ASec> (see chapter 9.5.1
Test
cell shorting ).
To release the shorting for another simultaneous running sequence (see chapter 9.6.2
Run two sequences simultaneously ) use the
DC_HVOff
procedure. It is recommended
always to use the
DC_HVOff
procedure after the shorting.
Sample:
var
DCShortingTime: integer;
…
begin
DCShortingTime:=300;
DC_Shorting(DCShortingTime);
DC_HVOff;
…
end.
DC_HVOff;
Release the DC HV Source and the shorting for another simultaneous running
sequence. It is recommended always to use this procedure after a
DC_Measurement
or
a
DC_Shorting
procedure.
