Setup Shunt Bar B Test – Memory Pattern Location 6:
:ROUT:MEM:CHAN 6,
(@104,105,117,118,121)
Specify relays to close.
:ROUT:MEM:SOUR:LEV 6,0.05,(@127)
Set Isrc to 50mA for M6.
:ROUT:MEM:DEL 6,0
Set Memory Delay = 0.
:SENS:VOLT:NPLC 1,(@M6)
Set A/D integration time to 1 PLC.
:CALC1:FORM S1I,(@M6)
Select S1IOHMS math function; selecting this
function automatically selects DCV measurement
function and the 1V measurement range.
:CALC1:STAT ON,(@M6)
Enable the math function.
:ROUT:MEM:READ:STAT 6,ON
Enable measurement during scan; during a scan the
measurement is initiated automatically. This does
not apply when a memory pattern is recalled as
shown below. In the latter case, the reading must be
initiated explicitly as also shown below.
Setup Open Circuit Test Voltage Verification – Memory Pattern Location 7:
:ROUT:MEM:CHAN 7,
(@109,112,122,113,118,123,121)
Specify relays to close (109 and 112 are shunt bars).
:ROUT:MEM:SOUR:LEV 7,500,(@128)
Set Vsrc to 500V for M7. Since source level is the
same as in Initial Setup routine, this command can
be left out.
:ROUT:MEM:DEL 7,0.05
Set Total Memory Delay = 50ms, allow 50ms settling
time after changing load on V-source; if also change
source level, include an additional 250ms for total of
300ms.
:SENS:FUNC 'VOLT',(@M7)
Select DC volts measurement function.
:SENS:VOLT:RANG 1000,(@M7)
Select 1000V fixed measurement range.
:SENS:VOLT:NPLC 1,(@M7)
Set A/D integration time to 1 PLC.
:ROUT:MEM:READ:STAT 7,ON
Enable measurement during scan; during a scan the
measurement is initiated automatically. This does
not apply when a memory pattern is recalled as
shown below. In the latter case, the reading must be
initiated explicitly as also shown below.
