HMP260-U017en-1.5 Appendix 1: Serial commands

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 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 <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 parameters:

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, 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 °C:

1 2 ... 63 64 65 66 67 68 69 70 71 72 73 ... 117 118
