Referenced Single Ended 13
Differential Voltage 14
(same hardware settings as full bridge)
Setting
:
1:1:INPT= 12\r\n
(unit 1, channel 1 input mode set to Full Bridge)
Setting Response: 1:INPT:ok
Query
:
The INPT query returns the channels input mode selection
Query Format: Unit#:Ch#:CMD?
Response format: Unit#:Cmd:Ch#:= <inpt>;
Query: 1:1:INPT?
Response: 1:INPT:1= 12;
Global Query: 1:0:INPT?
Global Response: 1:INPT:1= 12.0;2= 2.0;3= 2.0;4= 2.0;
NOTE:
Programmatic setting of Input mode should be followed with queries of IEXC, VEXC and GAIN since the unit
will set IEXC to 0 if a Bridge input is selected and likewise will set VEXC to 0 if ICP or Voltage input is selected.
Additionally, Bridge gain can be as high as 2000 but the ICP/Voltage mode maximum is 200 so switching from Bridge
to ICP/Voltage will reset the Gain to the ICP maximum if the current Bridge setting is higher than the ICP maximum.
IEXC
The IEXC command sets the current excitation level for ICP mode. The current excitation value is sent as an integer
value from 0 (off) to 20mA.
Setting
:
1:1:IEXC= 2\r\n (unit 1, channel 1, set to 2mA)
Setting Response: 1:IEXC:ok
Query
:
The IEXC query returns the units excitation value.
Query Format: Unit#:Ch#:CMD?
Response format: Unit#:Cmd:Ch#:= <IEXC>;
Query: 1:1:IEXC?
Response: 1:IEXC:1=2;
Global Query: 1:0: IEXC?
Global Response: 1:IEXC:1=2;2=4;3=4;4=4;
VEXC
The VEXC command sets the voltage excitation level for bridge and differential mode inputs.
The voltage excitation value is sent as a floating point number from 0.00 (off) to ±12.00 Volts. If the value is sent as a
negative number then the minus (-) Bridge Excitation will track the plus (+) Bridge Excitation setting. If it is sent as a
Positive value then the minus (-) Bridge Excitation will be set to 0.
