=
channel 1:
U
=
voltage output
I
=
current output
bb.bbb =
lower limit of channel 1
cc.ccc
=
upper limit of channel 1
d
=
channel 2:
U
=
voltage output
I
=
current output
ee.eee
=
lower limit of channel 2
ff.fff
=
upper limit of channel 2
The bb.bbb, cc.ccc, ee.eee and ff.fff parameters are entered in volts or milli-
amperes.
Example: lower limit of channel 1 is 0 V and upper limit 1 V
(U 0 1)
lower limit of channel 2 is 2 V and upper limit 10 V
(U 2 10)
