64 Programming the HP E1415 for PID Control
NOTE
The OUTPut:CURRent:AMPLitude command is only for programming
excitation current used in resistance measurement configurations. It is does
not program output DAC SCPs like the HP E1532.
The HP E1511 Strain Bridge Completion SCP has a programmable bridge
excitation voltage source. The command to control the excitation supply is
OUTPut:VOLTage:AMPLitude <amplitude>,(@<ch_list>)
•
The <amplitude> parameter can specify 0, 1, 2, 5, or 10 volts for the
HP E1511's excitation voltage.
•
The <ch_list> parameter specifies the SCP and bridge channel
excitation supply that will be programmed. There are four excitation
supplies in each HP E1511.
To set the excitation supplies for channels 0 through 3 to output 2 volts:
OUTP:VOLT:AMPL 2,(@100:103)
NOTE
The OUTPut:VOLTage:AMPLitude command is only for programming
excitation voltage used measurement configurations. It is does not program
output DAC SCPs like the HP E1531.
This step links each of the module's channels to a specific measurement
type. For analog input channels 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 vs. channel numbers.
The commands for linking EU conversion to channels are:
[SENSe:]FUNCtion:RESistance <excite_current>,[<range>,]
(@<ch_list>) for resistance measurements
[SENSe:]FUNCtion:STRain:
(@<ch_list>) for strain bridge measurements
[SENSe:]FUNCtion:TEMPerature <type>,<sub_type>,[<range>,]
(@<ch_list>) for temperature measurements with thermocouples,
thermistors, or RTDs
[SENSe:]FUNCtion:VOLTage <range>,(@<ch_list>) for voltage
measurements
[SENSe:]FUNCtion:CUSTom <range>,(@<ch_list>) for custom EU
conversions.
...
<excite_current>,[<range>,]
