6-10 External Triggering (Model 2306-VS Only)
TRIGger[1]:EXTernal:STEP:VOLTage <b> Applies to battery channel (#1)
TRIGger2:EXTernal:STEP:VOLTage <b> Applies to charger channel (#2)
These commands are used to change voltage stepping from ON or OFF. If ON, the voltage
will step when
the trigger in pulse is detected. If OFF, no voltage stepping is performed when
the trigger in pulse is detected. The default is OFF.
TRIGger[1]:EXTernal:STEP:VOLTage:END <NRf> Applies to battery channel (#1)
TRIGger2:EXTernal:STEP:VOLTage:END <NRf> Applies to charger channel (#2)
These commands set the voltage value when the trigger e
xternal enable setting is turned OFF
after being ON. The parameter has a minimum and default setting of 0 and maximum setting of
15. The END voltage becomes the voltage setting whenever external triggering is disabled,
which happens: (1) by commands to disable external triggering, (2) if the heat sink or power sup-
ply temperature is excessive, or (3) if the VPT
or current limit is tripped for either channel.
TRIGger[1]:EXTernal:STEP:READing <name> Applies to battery channel (#1)
TRIGger2:EXTernal:STEP:READing <name> Applies to charger channel (#2)
These commands set the reading/measurement mode. (The default is AUTO). With NONE
se
lected, no measurement is taken when the trigger in pulse is detected. Use NONE, if a channel
is going to be configured for voltage stepping only. If SYNC is selected, a synchronized pulse
current measurement will be triggered upon detecting the trigger in pulse. For SYNC, the only
measurement option is pulse current (see Section 3). To perform synchronized pulse current
measurements, a valid trigger level setting is needed to cause the detection of a rising or falling
pulse edge based on pulse current mode (HIGH/LOW or AVERage). With SYNC, a trigger pulse
is needed for trigger as well as one for detecting the pulse when taking measurements.
For AUTO, a measurement will be triggered automatically upon detecting the trigger in pulse.
W
ith AUTO, pulse current measurements no longer need a valid trigger level setting or need to
detect a rising or falling pulse edge before taking a measurement reading as they do for SYNC.
Besides pulse current measurements for AUTO, a voltage, current or DVM measurement may
be performed. Long integration measurements are not supported in SYNC or AUTO mode and
will generate settings conflict if selected. Error message: “+237, trigger external enable long
integration conflict”
TRIGger[1]:EXTernal:STEP:POINts <NRf> Applies to battery channel (#1)
TRIGger2:EXTernal:STEP:POINts <NRf> Applies to charger channel (#2)
These commands are used to change how many external measurements and/or voltage steps
to p
erform. The minimum and default setting is 1 while the maximum setting is 20.
TRIGger[1]:EXTernal:STEP:VPT <b> Applies to battery channel (#1)
TRIGger2:EXTernal:STEP:VPT <b> Applies to charger channel (#2)
These commands monitor for Voltage Protection Tripping (VPT) while using the
TRIGger:EXTernal features. (See Section 2 for VPT information). If not using trigger external
