To program the compliance value and compliance/measurement range.
L(level),(range)
level- Specifies the compliance level (I or V):
!-measure (236/237)
(238)
V-measure (236/238)
(237)
-100.00 to +100.00mA
-1.0000 to +
l.OOOOA
-110.00 to +llO.OOV
-1100.0 to +llOO.OV
range- Selects the compliance/measurement range:
1-source
0= Auto
1 =
lnA
2= lOnA
3= lOOnA
4 = lJ.lA
5 = lOJ.lA
6 = lOOJ.lA
7= lmA
8= lOrnA
9= lOOmA
10= 1A(238)

11 V (236, 237); lSV (238)

*Dlegal V-source option.
Upon power-up, or after receiving a DCL or SOC command, the instrument defaults
to the last
programmed selections. A JOX command sets the instrument to a compli-
ance level of
10mA/10Von a range of 10mA/11Vor lSV.
The L command sets the compliance level for the
programmed source and selects the
measurement range.
If the unit is programmed to source current, then the L com-
mand sets a voltage compliance and selects a voltage measurement range. Con-
versely,
if the unit is programmed to source voltage, the L command sets a current
compliance
and seleCts a current measurement range.
1. When a fixed range is specified, compliance range and measurement range are
the same.
2. With autorange selected, the programmed compliance value will be adjusted to
the highest on-scale range
and the measure range will be adjusted to the highest
on-scale measurement.
3.
In sweep operation, a change in compliance occurs immediately; in de operation,
a change
must be triggered to go into effect.
4. The US compliance value word indicates the voltage or current compliance value
