TimeOUT (other than the first): 2msec–200msec
First TimeOUT step: 10msec–60secs
0msec–100msec (in 10msec steps)
Define up to 19 delay sequence values using the
index and the time value (e.g. "1,1e-3" sets the first delay to
1ms). Ranges: 1-19 (parameter 1) and 0 to 100e-3
(parameter 2).
Define the delay sequence length (0 to 19). Specify

Specify whether (1) or not (0) to skip sequential
triggers.
1=Only requires 1 trigger
0 = Requires multiple triggers
Set trigger level for each TLEV step where x equals
1–20 (the maximum settings are based on the selected
current range. Therefore, the current range must be
selected before setting the step trigger level values)
Enable or disable pulse current fast readings.
Enable or disable pulse current search.
Enable or disable pulse current detection mode.
Specify length of timeout: 5ms - 32s incrementing in
1ms.
SENSe subsystem for charger channel (#2):
Select pulse current measurement function.
Pulse current configuration:
Specify average count:
1 to 100 (pulse current measurements), or
1 to 5000 (pulse current digitization).
Select measurement mode; HIGH, LOW or AVERage.
Set integration times:
Integration times set automatically.
Specify integration time (in sec) for high pulse
measurements; 33.33e-6 to 0.8333.
