Step 2. Linking Channels to EU Conversion

To set channels 0 through 9 to output 30 µA and channels 10 through 19 to
output 488 µA:
OUTP:CURR:AMPL 30e-6,(@100:109)
OUTP:CURR:AMPL 488e-6,(@110:119)
or to combine into a single command message:
OUTP:CURR:AMPL 30e-6,(@100:109);CURR 488e-6,(@110:119)
This step links each of the module's channels to a specific measurement
type. This " tells" the on-board control processor which EU conversion to
apply to the value read on any channel. The processor is creating a list of
conversion types versus channel numbers.
The commands for linking EU conversion to channels are:
[SENSe:]FUNCtion:RESistance <
for resistance measurements
[SENSe:]FUNCtion:STRain:<
for strain bridge measurements.
[SENSe:]FUNCtion:TEMPerature <
for temperature measurements with thermocouples, thermistors, or RTDs.
[SENSe:]FUNCtion:VOLTage <
for voltage measurements.
[SENSe:]FUNCtion:CUSTom <
for custom EU conversions.
1. At power-on and after
voltage for all 64 channels.
2. While the A/D filter is on (

may not specify autorange. The filtered settling time would
be too great for autorange to function. Use SCP filtering (filtering at
each channel) to allow use of autorange at high speed.
