1. ANALOGUE OUTPUT COMMANDS
AMODE Setting the analogue outputs
Disconnect the security lock jumper!
AMODE a bb.bbb cc.ccc d ee.eee ff.fff <cr>
a = 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.
Sets the analogue outputs on channels 1 and 2. An example of this is when the
voltage output on channel 1 is set to be 0...1 V and channel 2 set to 2...10 V:
>AMODE U 0 1 U 2 10 <cr>
Ch1 : 0.000 ... 1.000 V
Ch2 : 2.000 ... 10.000 V
The current settings can be checked by giving the command without any pa-
rameters:
>AMODE <cr>
Ch1 : 0.000 ... 20.000 mA
Ch2 : 0.000 ... 20.000 mA
ASEL Selecting the scaling the analogue output quantities
Disconnect the security lock jumper!
ASEL xxx yyy <cr>
xxx = channel 1's quantity
yyy = channel 2's quantity (RH, T, Td, dT, Abs, Mix or Tw)
