Programming examples: long integration measurements
The following command sequence will trigger and return one long integration
measurement:
Battery channel (#1)
SENS:RANG 5
‘ Select 5 A range.
VOLT 15
‘ Set output voltage to 15 V.
CURR 0.75
‘ Set current limit to 750 mA.
OUTP ON
‘ Turn output on.
SENS:LINT:TEDG RISING
‘ Select rising trigger edge to initiate
measurement.
SENS:LINT:TLEV 0.1
‘ Set trigger level to 100mA for 5 A trigger
level range.
SENS:LINT:TIME:AUTO
‘ Set integration time automatically for
single pulse.
SENS:FUNC “LINT”
‘ Select long integration function.
NOTE
LONG INT TRIG NOT DETECTED message
:
This message may take a few seconds to appear. With the
trigger edge set to RISING or FALLING, this message may
appear if the level setting causes no rising or falling edge
detection. A valid trigger level is not required if the trigger edge
is set to NEITHER. For the battery channel (#1), this message
will only appear if the trigger level setting corresponds to the
selected current range. For the charger channel (#2), the trigger
level setting only applies to the 5 A current range.
If you select AUTO TIME to set the integration time, the pulse
timeout message LONG INT TRIG NOT DETECTED will display
if the output is OFF. This message indicates that the integration
time has not been updated. To update the integration time,
select AUTO TIME after the output is turned ON.
