ANALOGUE OUTPUT COMMANDS

AMODE

Setting the analogue outputs

Disconnect the security lock jumper!

AMODE a bb.bbb cc.ccc d ee.eee ff.fff

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 milliamperes.

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

Ch1 : 0.000 ... 1.000 V

Ch2 : 2.000 ... 10.000 V

The current settings can be checked by giving the command without any parameters:

AMODE

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

xxx

=

channel 1's quantity

yyy

=

channel 2's quantity (RH, T, Td, Abs, Mix or Tw)

For example, relative humidity is selected to be output on channel 1 and temperature on
channel 2; the temperature range is scaled to 0...100
